[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 371,981, filed on August 19, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates generally to systems and methods for determining a match, and more particularly, to systems and methods for determining a match based on sleep information. Background Art

[0004] Many individuals suffer from sleep-related and / or breathing-related disorders, such as, for example, sleep-disordered breathing (SDB), which may include obstructive sleep apnea (OSA), central sleep apnea (CSA), other types of apnea (such as mixed apnea and hypopnea), respiratory effort-related micro-arousal (RERA) and snoring. In some cases, these disorders may appear or appear more obviously when the individual is in a specific lying / sleeping posture. These individuals may also suffer from other health conditions (which may be referred to as comorbidities), such as insomnia (e.g., difficulty falling asleep, frequent or long awakenings after initially falling asleep, and / or early awakening and inability to fall asleep again), periodic limb movement disorder (PLMD), restless legs syndrome (RLS), Cheyne-Stokes respiration (CSR), respiratory insufficiency, obesity hyperventilation syndrome (OHS), chronic obstructive pulmonary disease (COPD), neuromuscular disease (NMD), rapid eye movement (REM) behavior disorder (also referred to as RBD), dream enactment behavior (DEB), hypertension, diabetes, stroke, chest wall disorder.

[0005] These disorders are often treated using respiratory therapy systems (e.g., continuous positive airway pressure (CPAP) systems), which deliver pressurized air to help prevent an individual's airway from narrowing or collapsing during sleep. However, some users find such systems uncomfortable, difficult to use, expensive, unsightly, and / or unable to perceive the benefits associated with using the systems. As a result, some users will choose not to use or cease using a respiratory therapy system without demonstrating the severity of their symptoms when not using respiratory therapy treatment, or without receiving encouragement or confirmation that the respiratory therapy system is improving their sleep quality and alleviating the symptoms of these disorders. The present disclosure is intended to address these and other issues. Summary of the invention

DETAILED DESCRIPTION

[0028] Many individuals suffer from sleep-related and / or breathing disorders, such as sleep-disordered breathing (SDB), such as obstructive sleep apnea (OSA), central sleep apnea (CSA) and other types of apnea, respiratory effort-related arousals (RERA), snoring, Cheyne-Stokes respiration (CSR), respiratory insufficiency, obesity hyperventilation syndrome (OHS), chronic obstructive pulmonary disease (COPD), periodic limb movement disorder (PLMD), restless legs syndrome (RLS), neuromuscular diseases (NMDs), and chest wall disorders.

[0029] Obstructive sleep apnea (OSA), a form of sleep-disordered breathing (SDB), is characterized by events that include occlusion or obstruction of the upper airway during sleep caused by a combination of an abnormally small upper airway and loss of normal muscle tone in the tongue, soft palate, and posterior oropharyngeal wall areas. More generally, apnea generally refers to breathing cessation caused by air obstruction (obstructive sleep apnea) or cessation of respiratory function (commonly known as central sleep apnea). CSA occurs when the brain temporarily stops sending signals to the muscles that control breathing. Typically, during an obstructive sleep apnea event, an individual will stop breathing for about 15 seconds to about 30 seconds.

[0030] Other types of apnea include hypopnea, hyperpnea, and hypercapnia. Hypopnea is usually characterized by slow or shallow breathing caused by narrow airways, rather than blocked airways. Hyperpnea is usually characterized by increased depth and / or rate of breathing. Hypercapnia is usually characterized by excess carbon dioxide in the bloodstream, usually caused by hypopnea.

[0031] Respiratory effort related arousal (RERA) events are typically characterized by increased respiratory effort lasting ten seconds or longer, resulting in arousal from sleep, and which do not meet the criteria for an apnea or hypopnea event. RERA is defined as a respiratory sequence characterized by increased respiratory effort resulting in arousal from sleep, but which does not meet the criteria for an apnea or hypopnea event. These events meet the following criteria: (1) a pattern of gradually more negative esophageal pressures, terminated by a sudden change in pressure to a lower negative level and a micro-arousal, and (2) the event lasts for 10 seconds or longer. In some embodiments, the nasal cannula / pressure transducer system is sufficient and reliable in the detection of RERA. The RERA detector can be based on an actual flow signal derived from a respiratory therapy device. For example, a flow limitation measure can be determined based on the flow signal. A wake-up measure can then be derived based on the flow limitation measure and the measure of the sudden increase in ventilation. One such method is described in WO 2008 / 138040 and U.S. Patent No. 9,358,353, assigned to ResMed Ltd., the disclosure of each of which is hereby incorporated by reference in its entirety.

[0032] Cheyne-Stokes respiration (CSR) is another form of sleep-disordered breathing. CSR is a disorder of the patient's respiratory controller in which there are rhythmic alternating cycles of waxing and waning ventilation called CSR cycles. CSR is characterized by repeated deoxygenation and reoxygenation of arterial blood.

[0033] Obesity hyperventilation syndrome (OHS) is defined as the combination of severe obesity and chronic hypercapnia during wakefulness in the absence of other known causes of hypoventilation. Symptoms include dyspnea, morning headache, and excessive daytime sleepiness.

[0034] Chronic obstructive pulmonary disease (COPD) encompasses any of a group of lower airway diseases that have certain common features, such as increased resistance to the movement of air, prolonged expiratory phase of breathing, and loss of normal elasticity of the lungs. COPD encompasses a group of lower airway diseases that have certain common features, such as increased resistance to the movement of air, prolonged expiratory phase of breathing, and loss of normal elasticity of the lungs.

[0035] Neuromuscular diseases (NMDs) encompass a wide range of diseases and ailments that impair muscle function either directly through intrinsic muscle pathology or indirectly through neuropathology.Chest wall disorders are a group of thoracic deformities that result in inefficient connections between the respiratory muscles and the thorax.

[0036] These and other disorders are characterized by specific events that occur while an individual is sleeping (e.g., snoring, apnea, hypopnea, restless legs, sleep disturbances, choking, increased heart rate, breathing difficulties, asthma attacks, seizures, epileptic seizures, or any combination thereof).

[0037] The Apnea-Hypopnea Index (AHI) is an index used to indicate the severity of sleep apnea during a sleep session. The AHI is calculated by dividing the number of apnea and / or hypopnea events experienced by the AHI user during a sleep session by the total number of hours slept in the sleep session. The event can be, for example, an apnea that lasts at least 10 seconds. An AHI of less than 5 is considered normal. An AHI greater than or equal to 5 but less than 15 is considered an indication of shallow sleep apnea. An AHI greater than or equal to 15 but less than 30 is considered an indication of moderate sleep apnea. An AHI greater than or equal to 30 is considered an indication of severe sleep apnea. In children, an AHI greater than 1 is considered abnormal. Sleep apnea can be considered "controlled" when the AHI is normal, or when the AHI is normal or mild. The AHI can also be used in conjunction with oxygen desaturation levels to indicate the severity of obstructive sleep apnea.

[0038] refer to Figure 1 , shows a system 10 according to some embodiments of the present disclosure. The system 10 includes a respiratory therapy system 100, a control system 200, one or more sensors 210, a user device 260, and an activity tracker 270.

[0039] The respiratory therapy system 100 includes a respiratory pressure therapy (RPT) device 110 (referred to herein as respiratory therapy device 110), a user interface 120 (also referred to as a mask or patient interface), a conduit 140 (also referred to as a tube or air circuit), a display device 150, and a humidifier 160. Respiratory pressure therapy refers to the application of an air supply to the entrance of a user's airway at a controlled target pressure that is nominally positive relative to atmosphere throughout the user's breathing cycle (e.g., in contrast to negative pressure therapy such as a canister ventilator or chest plate). The respiratory therapy system 100 is typically used to treat individuals suffering from one or more sleep-related breathing disorders (e.g., obstructive sleep apnea, central sleep apnea, or mixed sleep apnea).

[0040] The respiratory therapy system 100 can be used, for example, as a ventilator or a positive airway pressure (PAP) system, such as a continuous positive airway pressure (CPAP) system, an automatic positive airway pressure system (APAP), a bi-level or variable positive airway pressure system (BPAP or VPAP), or any combination thereof. The CPAP system delivers a predetermined air pressure (e.g., determined by a sleep physician) to the user. The APAP system automatically changes the air pressure delivered to the user based on, for example, respiratory data associated with the user. The BPAP or VPAP system is configured to deliver a first predetermined pressure (e.g., inspiratory positive airway pressure or IPAP) and a second predetermined pressure (e.g., expiratory positive airway pressure or EPAP) that is lower than the first predetermined pressure.

[0041] like Figure 2 As shown, respiratory therapy system 100 can be used to treat user 20. In this example, user 20 of respiratory therapy system 100 and bed partner 30 are located on bed 40 and lying on mattress 42. User interface 120 can be worn by user 20 during a sleep session. Respiratory therapy system 100 generally helps increase air pressure in the throat of user 20 to help prevent airway closure and / or narrowing during sleep. Respiratory therapy device 110 can be positioned in direct proximity to a user such as Figure 2 The bed 40 is shown on a nightstand 44 , or more generally, positioned on any surface or structure generally adjacent to the bed 40 and / or the user 20 .

[0042] The respiratory therapy device 110 is generally used to generate pressurized air delivered to the user (e.g., using one or more motors driving one or more compressors). In some embodiments, the respiratory therapy device 110 generates a continuous constant air pressure delivered to the user. In other embodiments, the respiratory therapy device 110 generates two or more predetermined pressures (e.g., a first predetermined air pressure and a second predetermined air pressure). In other embodiments, the respiratory therapy device 110 generates a variety of different air pressures within a predetermined range. For example, the respiratory therapy device 110 can deliver at least about 6 cmH 2 O, at least about 10cmH 2 O, at least about 20cmH 2 O, about 6cmH 2 O and about 10cmH 2 O, about 7cmH 2 O and about 12cmH 2 The breathing apparatus 110 may also deliver pressurized air at a predetermined flow rate, for example, between about -20 L / min and about 150 L / min, while maintaining a positive pressure (relative to ambient pressure).

[0043] Respiratory therapy device 110 includes housing 112, blower motor 114, air inlet 116, and air outlet 118 ( Figure 1 ). refer to Figure 3A and Figure 3B , the blower motor 114 is at least partially disposed or integrated within the housing 112. The blower motor 114 draws air from outside the housing 112 (e.g., the atmosphere) via the air inlet 116 and causes the pressurized air to flow through the humidifier 160 and through the air outlet 118. In some embodiments, the air inlet 116 and / or the air outlet 118 include a cover that is movable between a closed position and an open position (e.g., to prevent or inhibit air from flowing through the air inlet 116 or the air outlet 118). Figure 3A and Figure 3B As shown, housing 112 may include vent 113 to allow air to pass through housing 112 to air inlet 116. Conduit 140 is coupled to air outlet 118 of respiratory therapy device 110 as described below.

[0044] Return to reference Figure 1, user interface 120 engages a portion of the user's face and delivers pressurized air from respiratory therapy device 110 to the user's airway to help prevent the airway from narrowing and / or collapsing during sleep. This can also increase the user's oxygen intake during sleep. Generally, user interface 120 engages the user's face so that pressurized air is delivered to the user's airway via the user's mouth, the user's nose, or the user's mouth and nose. Respiratory therapy device 110, user interface 120, and conduit 140 together form an air passageway that is fluidly coupled to the user's airway. Pressurized air also increases the user's oxygen intake during a sleep session. Depending on the therapy to be applied, user interface 120 can, for example, form a seal with an area or portion of the user's face to facilitate a sufficient difference in pressure from ambient pressure (e.g., about 10 cmH relative to ambient pressure). 2 O) to achieve therapy. For other forms of therapy, such as delivery of oxygen, the user interface may not include a user interface sufficient to facilitate delivery of gas at about 10 cmH 2 A gas supply of O is delivered under positive pressure to the seal of the airway.

[0045] The user interface 120 may include, for example, a cushion 122, a frame 124, a head cover 126, a connector 128, and one or more vents 130. The cushion 122 and the frame 124 define a volume of space around the user's mouth and / or nose. When the respiratory therapy system 100 is in use, the volume space (e.g., from the respiratory therapy device 110 via the conduit 140) receives pressurized air to enter the user's airway. The head cover 126 is generally used to help position and / or stabilize the user interface 120 on a part of the user (e.g., face), and together with the cushion 122 (which may, for example, include silicone, plastic, foam, etc.), help provide a substantially airtight seal between the user interface 120 and the user 20. In some embodiments, the head cover 126 includes one or more bands (e.g., including hook-and-loop fasteners). The connector 128 is generally used to couple (e.g., connect and fluidly couple) the conduit 140 to the cushion 122 and / or frame 124. Alternatively, conduit 140 may be coupled directly to cushion 122 and / or frame 124 without connector 128. Vent 130 may be used to allow carbon dioxide and other gases exhaled by user 20 to escape. User interface 120 may generally include any suitable number of vents (e.g., one, two, five, ten, etc.).

[0046] like Figure 2As shown, in some embodiments, the user interface 120 is a mask (e.g., a full face mask) that covers at least a portion of the nose and mouth of the user 20. Alternatively, the user interface 120 may be a nasal mask that provides air to the user's nose or a nasal pillow mask that delivers air directly to the nostrils of the user 20. In other embodiments, the user interface 120 includes a mouthpiece (e.g., a night guard mouthpiece molded to conform to the user's teeth, a jaw repositioning device, etc.).

[0047] refer to Figure 4A and Figure 4B , illustrating a method for interacting with a user interface 120 ( Figure 1 ) The user interface 400 is the same or similar to the user interface 400. The user interface 400 generally includes a cushion 430 and a frame 450, which define the volume of the space around the user's mouth and / or nose. When in use, the volume of the space receives pressurized air to enter the user's airway. In some embodiments, the cushion 430 and the frame 450 of the user interface 400 form an integral part of the user interface. The user interface 400 may also include a head cover 410, which generally includes a belt assembly and optionally includes a connector 470. The head cover 410 is configured to be positioned approximately around at least a portion of the user's head when the user wears the user interface 400. The head cover 410 can be coupled to the frame 450 and positioned on the user's head so that the user's head is positioned between the head cover 410 and the frame 450. The cushion 430 is positioned between the user's face and the frame 450 to form a seal on the user's face. The connector 470 is configured to be coupled to the frame 450 and / or the cushion 430 at one end and to the conduit (not shown) of the respiratory therapy device. Pressurized air can flow directly from the conduit of the respiratory therapy system through connector 470 into the volume of the space defined by cushion 430 (or cushion 430 and frame 450) of user interface 400. Pressurized air passes from user interface 400 through the user's mouth, nose, or both to the user's airway. Alternatively, where user interface 400 does not include connector 470, the conduit of the respiratory therapy system can be directly connected to cushion 430 and / or frame 450.

[0048] In some embodiments, the connector 470 may include one or more vents 472 (e.g., multiple vents) on the body of the connector 470 itself and / or one or more vents 476 ("diffuser vents") proximate the frame 450 for allowing the user's exhaled carbon dioxide (CO 2) and other gases escape. In some embodiments, one or more vents (such as vents 472 and / or 476) can be located in the user interface 400 (such as in the frame 450) and / or in the conduit 140. In some embodiments, the frame 450 includes at least one anti-asphyxia valve (AAV) 474 that allows the user's exhaled CO to escape in the event that the vent (e.g., vent 472 or 476) fails when the respiratory therapy device is activated. 2 Typically, full face masks have an AAV (e.g., AAV 474) present (e.g., as a safety feature); however, diffuser vents and vents located on the mask or connector (typically an array of holes in the mask material itself or a mesh made of some fabric, which is replaceable in many cases) are not necessarily present at the same time (e.g., some masks may have only diffuser vents, such as vents 476, and other masks may have only vents 472 on the connector itself).

[0049] refer to Figure 5A and Figure 5B , illustrating a method for interacting with a user interface 120 ( Figure 1 ) is the same or similar user interface 500. The user interface 500 is the same as or similar to the user interface 400 ( Figure 4A and Figure 4B ) in that user interface 500 is an indirect user interface, whereas user interface 400 is a direct user interface. Interface 500 includes headgear 510 (e.g., as a belt assembly), cushion 530, frame 550, connector 570, and user interface conduit 590 (commonly referred to as a mini tube or flexible tube). User interface 500 is an indirectly connected user interface because pressurized air is delivered to cushion 530 and / or frame 550 from conduit 140 of the respiratory therapy system through user interface conduit 590 rather than directly from conduit 140 of the respiratory therapy system.

[0050] In some embodiments, the cushion 530 and the frame 550 form an integral part of the user interface 500. Generally, the user interface conduit 590 is larger than the conduit 140 ( Figure 1 ) is more flexible and / or has a smaller diameter than the diameter of the conduit 140. The user interface conduit 590 is typically shorter than the conduit 140. A headgear 310 (similar to the user interface 300) FIG. 3A to FIG. 3B), the headgear 510 of the user interface 500 is configured to be positioned generally around at least a portion of the user's head when the user wears the user interface 500. The headgear 510 can be coupled to the frame 550 and positioned on the user's head so that the user's head is positioned between the headgear 510 and the frame 550. The cushion 530 is positioned between the user's face and the frame 550 to form a seal on the user's face. The connector 570 is configured to be coupled to the frame 550 and / or the cushion 530 at one end and to the conduit 590 of the user interface 500 at the other end. In other embodiments, the conduit 590 can be directly connected to the frame 550 and / or the cushion 530. The conduit 590 is configured to be connected to the conduit 140 at the opposite end relative to the frame 550 and the cushion 530. Pressurized air may flow from the conduit 140 of the respiratory therapy system, through the user interface conduit 590 and connector 570, and into the volume of space defined by the cushion 530 (or cushion 530 and frame 550) of the user interface 500 against the user's face. From this volume of space, the pressurized air passes through the user's mouth, nose, or both to the user's airway.

[0051] In some embodiments, connector 570 includes a plurality of vents 572 for allowing carbon dioxide (CO2) exhaled by the user to be released when the respiratory therapy device is activated. 2 ) and other gases escape. In such embodiments, each of the plurality of vents 572 is an opening that can be angled relative to the thickness of the connector wall forming the opening. The angled opening can reduce CO 2 and other gases escaping into the atmosphere. Due to the reduced noise, the acoustic signal associated with the plurality of vents 572 may be more apparent to the internal microphone rather than the external microphone. Thus, the internal microphone may be located within or otherwise physically integrated with the respiratory therapy system and acoustically communicate with the air flow that, in operation, is generated by the flow generator of the respiratory therapy device and reaches the user interface 500 through the conduit.

[0052] In some embodiments, connector 570 optionally includes at least one valve 574 for allowing CO exhaled by the user to flow out when the respiratory therapy device is inactive. 2 In some embodiments, valve 574 (an example of an anti-asphyxia valve) includes a silicone (or other suitable material) flap that is a fail-safe component that allows the user to exhale CO in the event that vent 572 fails while the respiratory therapy device is activated. 2 In such embodiments, when the silicone valve flap is opened, the valve opening is much larger than each vent opening and is therefore less likely to be blocked by obstructive material.

[0053] refer to Fig. 6A and Figure 6B , illustrating a method for interacting with a user interface 120 ( Figure 1 ) is the same or similar user interface 600. User interface 600 is similar to user interface 500 in that it is an indirect user interface. Indirect headgear user interface 600 includes headgear 610, cushion 630, and connector 670. Headgear 610 includes strap 610a and headgear conduit 610b. Similar to user interface 400 ( FIG. 4A to FIG. 4B ) and user interface 500( FIG. 5A to FIG. 5B ), the headgear 610 is configured to be positioned generally around at least a portion of the user's head when the user wears the user interface 600. The headgear 610 includes a strap 610a that can be coupled to a headgear conduit 610b and positioned on the user's head so that the user's head is positioned between the strap 610a and the headgear conduit 610b. The cushion 630 is positioned between the user's face and the headgear conduit 610b to form a seal on the user's face.

[0054] The connector 670 is configured to couple to the headgear 610 at one end and to a conduit of a respiratory therapy system (e.g., conduit 140) at another end. In other embodiments, the connector 670 is not included and the headgear 610 may instead be directly connected to the conduit of the respiratory therapy system. The headgear conduit 610b may be configured to deliver pressurized air from the conduit of the respiratory therapy system to the cushion 630, or more specifically, to the volume of space surrounding the mouth and / or nose of the user and enclosed by the user cushion. The headgear conduit 610b is hollow to provide a passage for pressurized air. Both sides of the headgear conduit 610b may be hollow to provide two passages for pressurized air. Alternatively, only one side of the headgear conduit 610b may be hollow to provide a single passage. In Fig. 6A and Figure 6B In the illustrated embodiment, the headgear conduit 610b includes two channels that are positioned on either side of the user's head / face in use. Alternatively, only one channel of the headgear conduit 610b can be hollow to provide a single channel. Pressurized air can flow from the conduit of the respiratory therapy system through the connector 670 and the headgear conduit 610b and into the volume of space between the cushion 630 and the user's face. The pressurized air reaches the user's airway from the volume of space between the cushion 630 and the user's face through the user's mouth, nose, or both.

[0055] In some embodiments, the cushion 630 includes a plurality of vents 672 on the cushion 630 itself. Additionally or alternatively, in some embodiments, the connector 670 includes a plurality of vents 676 ("diffuser vents") proximate the headgear 610 for allowing the user's exhaled carbon dioxide (CO 2 ) and other gases can escape. In some embodiments, the headgear 610 may include at least one additional anti-asphyxia valve (AAV) 674 proximal to the cushion 630 to allow the user's exhaled CO to escape in the event that a vent (e.g., vent 672 or 676) fails when the respiratory therapy device is activated. 2 and other gases escape.

[0056] Return to reference Figure 1 , conduit 140 (also referred to as an air circuit or tube) allows air to flow between components of respiratory therapy system 100, such as between respiratory therapy device 110 and user interface 120. In some embodiments, there may be separate branches of the conduit for inhalation and exhalation. In other embodiments, a single branch conduit is used for inhalation and exhalation.

[0057] refer to Figure 3A , the conduit 140 includes a first end 142 that is coupled to the air outlet 118 of the respiratory therapy device 110. The first end 142 can be coupled to the air outlet 118 of the respiratory therapy device 110 using various techniques (e.g., a press fit connection, a snap fit connection, a threaded connection, etc.). In some embodiments, the conduit 140 includes one or more heating elements that heat the pressurized air flowing through the conduit 140 (e.g., heating the air to a predetermined temperature or within a predetermined temperature range).

In such embodiments, speaker 222 generates or transmits sound waves at predetermined intervals, and microphone 220 detects reflections of the transmitted sound waves from speaker 222. The sound waves generated or emitted by speaker 222 have a frequency that is inaudible to the human ear (e.g., below 20 Hz or above about 18 kHz) so as not to disturb the sleep of user 20 or bed partner 30 ( Figure 2 Based at least in part on the data from microphone 220 and / or speaker 222, control system 200 may determine that user 20 ( Figure 2 and / or one or more of the sleep-related parameters described herein, such as a respiratory signal, a respiratory rate, an inspiratory amplitude, an expiratory amplitude, an inspiratory-expiratory ratio, a number of events per hour, a pattern of events, a sleep state, a sleep stage, a pressure setting of the respiratory therapy device 110, or any combination thereof.

EMG sensor 248 outputs physiological data associated with electrical activity generated by one or more muscles. Oxygen sensor 250 outputs oxygen data indicating the oxygen concentration of a gas (e.g., in conduit 140 or at user interface 120). Oxygen sensor 250 can be, for example, an ultrasonic oxygen sensor, an electrical oxygen sensor, a chemical oxygen sensor, an optical oxygen sensor, a pulse oximeter (e.g., SpO 2 sensor) or any combination thereof.

[0087] The analyte sensor 252 can be used to detect the presence of an analyte in the exhaled breath of the user 20. The data output by the analyte sensor 252 can be stored in the memory device 204 and used by the control system 200 to determine the identity and concentration of any analyte in the user's breath. In some embodiments, the analyte sensor 174 is located near the user's mouth to detect analytes in the breath exhaled from the user's mouth. For example, when the user interface 120 is a mask covering the user's nose and mouth, the analyte sensor 252 can be located in the mask to monitor the user's mouth breathing. In other embodiments, such as when the user interface 120 is a nasal mask or a nasal pillow mask, the analyte sensor 252 can be positioned near the user's nose to detect analytes in the breath exhaled through the user's nose. In other embodiments, when the user interface 120 is a nasal mask or a nasal pillow mask, the analyte sensor 252 can be positioned near the user's mouth. In this embodiment, the analyte sensor 252 can be used to detect whether any air leaks unintentionally from the user's mouth and / or the user interface 120. In some embodiments, the analyte sensor 252 is a volatile organic compound (VOC) sensor that can be used to detect carbon-based chemicals or compounds. In some embodiments, the analyte sensor 174 can also be used to detect whether the user is breathing through their nose or mouth. For example, if data output by the analyte sensor 252 positioned near the user's mouth or positioned within the mask (e.g., in embodiments where the user interface 120 is a mask) detects the presence of an analyte, the control system 200 can use this data as an indication that the user is breathing through their mouth.

[0088] The humidity sensor 254 outputs data that can be stored in the memory device 204 and used by the control system 200. The humidity sensor 254 can be used to detect humidity in various areas surrounding the user (e.g., within the conduit 140 or the user interface 120, near the user's face, near the connection between the conduit 140 and the user interface 120, near the connection between the conduit 140 and the respiratory therapy device 110, etc.). Therefore, in some embodiments, the humidity sensor 254 can be connected to the user interface 120 or the conduit 140 or integrated in the user interface or in the conduit to monitor the humidity of the pressurized air from the respiratory therapy device 110. In other embodiments, the humidity sensor 254 is placed near any area where the humidity level needs to be monitored. The humidity sensor 254 can also be used to monitor the humidity of the surrounding environment surrounding the user, such as the air in a bedroom.

[0089] Light detection and ranging (LiDAR) sensor 256 can be used for depth sensing. This type of optical sensor (e.g., laser sensor) can be used to detect objects and build a three-dimensional (3D) map of the surrounding environment (e.g., living space). LiDAR can usually use pulsed lasers to measure time of flight. LiDAR is also called 3D laser scanning. In an example using such a sensor, a fixed or mobile device (such as a smart phone) with a LiDAR sensor 256 can measure and map an area extending 5 meters or more from the sensor. For example, LiDAR data can be fused with point cloud data estimated by an electromagnetic RADAR sensor. LiDAR sensor 256 can also use artificial intelligence (AI) to automatically enable the RADAR system to enter a geofence by detecting and classifying features in the space that may cause problems for the RADAR system, such as glass windows (which may be highly reflective to the RADAR). For example, LiDAR can also be used to provide an estimate of a person's height, as well as changes in height when a person sits down or falls. LiDAR can be used to form a 3D grid representation of the environment. In a further application, for solid surfaces through which radio waves pass (e.g., radio-transmissive materials), LiDAR can reflect off such surfaces, allowing classification of different types of obstacles.

[0090] In some embodiments, one or more sensors 210 also include a galvanic skin response (GSR) sensor, a blood flow sensor, a respiration sensor, a pulse sensor, a sphygmomanometer sensor, an oximeter sensor, a sonar sensor, a RADAR sensor, a blood glucose sensor, a color sensor, a pH sensor, an air quality sensor, a tilt sensor, a rain sensor, a soil moisture sensor, a water flow sensor, an alcohol sensor, or any combination thereof.

[0091] Although in Figure 110, but any combination of one or more sensors 210 may be integrated into and / or coupled to any one or more of the components of system 100, including respiratory therapy device 110, user interface 120, conduit 140, humidifier 160, control system 200, user device 260, activity tracker 270, or any combination thereof. For example, microphone 220 and speaker 222 may be integrated into and / or coupled to user device 260, and pressure sensor 212 and / or flow sensor 132 may be integrated into and / or coupled to respiratory therapy device 110. In some embodiments, at least one of the one or more sensors 210 is not coupled to respiratory therapy device 110, control system 200, or user device 260, and is generally positioned adjacent to user 20 during a sleep session (e.g., positioned on or in contact with a portion of user 20, worn by user 20, coupled to or positioned on a nightstand, coupled to a mattress, coupled to a ceiling, etc.).

[0092] One or more of respiratory therapy device 110, user interface 120, conduit 140, display device 150, and humidifier 160 may include one or more sensors (e.g., a pressure sensor, a flow sensor, a microphone, or more generally any of other sensors 210 described herein). These one or more sensors may be used, for example, to measure the air pressure and / or flow of pressurized air supplied by respiratory therapy device 110.

[0093] Data from one or more sensors 210 may be analyzed (e.g., by the control system 200) to determine one or more sleep-related parameters, which may include a respiratory signal, a respiratory rate, a respiratory pattern, an inspiratory amplitude, an expiratory amplitude, an inspiratory-expiratory ratio, the occurrence of one or more events, the number of events per hour, an event pattern, a sleep state, an apnea-hypopnea index (AHI), or any combination thereof. The one or more events may include snoring, apnea, central apnea, obstructive apnea, mixed apnea, hypopnea, mask leak, cough, restless legs, sleep disorders, choking, increased heart rate, dyspnea, asthma attack, epileptic seizure, increased blood pressure, or any combination thereof. Many of these sleep-related parameters are physiological parameters, although some of the sleep-related parameters may be considered non-physiological parameters. Other types of physiological parameters and non-physiological parameters may also be determined based on data from one or more sensors 210 or based on other types of data.

[0094] User equipment 260 ( Figure 1) includes a display device 262. User device 260 can be, for example, a mobile device such as a smart phone, a tablet, a game console, a smart watch, a laptop, etc. Alternatively, user device 260 can be an external sensing system, a television (e.g., a smart TV) or another smart home device (e.g., a smart speaker, such as Google Home, Amazon Echo, Alexa, etc.). In some embodiments, the user device is a wearable device (e.g., a smart watch). Display device 262 is generally used to display images including still images, video images, or both. In some embodiments, display device 262 acts as a human-machine interface (HMI), which includes a graphical user interface (GUI) configured to display images and an input interface. Display device 262 can be an LED display, an OLED display, an LCD display, etc. The input interface can be, for example, a touch screen or a touch-sensitive substrate, a mouse, a keyboard, or any sensor system configured to sense input made by a human user interacting with user device 260. In some embodiments, one or more user devices can be used by system 10 and / or included in system 10.

[0095] In some embodiments, the system 100 also includes an activity tracker 270. The activity tracker 270 is generally used to help generate physiological data associated with the user. The activity tracker 270 includes one or more of the sensors 210 described herein, such as, for example, a motion sensor 138 (e.g., one or more accelerometers and / or gyroscopes), a PPG sensor 154, and / or an ECG sensor 156. The physiological data from the activity tracker 270 can be used to determine, for example, the number of steps, the distance traveled, the number of steps climbed, the duration of physical activity, the type of physical activity, the intensity of physical activity, the time spent standing, the breathing rate, the average breathing rate, the resting breathing rate, the maximum HE breathing heart rate, the breathing rate variability, the heart rate, the average heart rate, the resting heart rate, the maximum heart rate, the heart rate variability, the number of calories burned, the blood oxygen saturation, the skin electrode activity (also known as skin conductance or skin electrode response) or any combination thereof. In some embodiments, the activity tracker 270 is connected to the user device 260 (e.g., electronically or physically).

[0096] In some embodiments, the activity tracker 270 is a wearable device that can be worn by a user, such as a smart watch, wristband, ring, or patch. Figure 2, activity tracker 270 is worn on the wrist of user 20. Activity tracker 270 may also be coupled to or integrated into a garment or clothing worn by the user. Still alternatively, activity tracker 270 may also be coupled to or integrated into user device 260 (e.g., within the same housing). More generally, activity tracker 270 may be communicatively coupled to or physically integrated into control system 200, memory 204, respiratory therapy system 100, and / or user device 260 (e.g., within a housing).

[0097] In some embodiments, the system 100 also includes a blood pressure device 280. The blood pressure device 280 is generally used to assist in generating cardiovascular data for determining one or more blood pressure measurements associated with the user 20. The blood pressure device 280 may include at least one of the one or more sensors 210 to measure, for example, a systolic blood pressure component and / or a diastolic blood pressure component.

[0098] In some embodiments, blood pressure device 280 is a sphygmomanometer that includes an inflatable cuff and a pressure sensor (e.g., pressure sensor 212 described herein) that can be worn by user 20. For example, in Figure 2 In the example of , the blood pressure device 280 can be worn on the upper arm of the user 20. In such embodiments where the blood pressure device 280 is a sphygmomanometer, the blood pressure device 280 also includes a pump (e.g., a manually operated bulb) for inflating the cuff. In some embodiments, the blood pressure device 280 is coupled to the respiratory therapy device 110 of the respiratory therapy system 100, which in turn delivers pressurized air to inflate the cuff. More generally, the blood pressure device 280 can be communicatively coupled to and / or physically integrated into (e.g., within a housing) the control system 200, the memory device 204, the respiratory therapy system 100, the external device 260, and / or the activity tracker 270.

[0099] In other embodiments, the blood pressure device 280 is a mobile blood pressure monitor communicatively coupled to the respiratory therapy system 100. The mobile blood pressure monitor includes a portable recording device attached to a band or belt worn by the user 20 and an inflatable cuff attached to the portable recording device and worn around the arm of the user 20. The dynamic blood pressure monitor is configured to measure blood pressure between about every 15 minutes to about 30 minutes over a 24-hour or 48-hour period. The dynamic blood pressure monitor can simultaneously measure the heart rate of the user 20. These multiple readings are averaged over a 24-hour period. The mobile blood pressure monitor determines any changes in the blood pressure and heart rate of the user 20 measured during the sleep period and the wake period of the user 20, as well as any distribution and / or trend patterns of the blood pressure and heart rate data. The measured data and statistical data can then be transmitted to the respiratory therapy system 100.

[0100] The blood pressure device 280 can be positioned external to the respiratory therapy system 100, coupled directly or indirectly to the user interface 120, coupled directly or indirectly to a headgear associated with the user interface 120, or inflatably coupled to a portion of or around the user 20. The blood pressure device 280 is generally used to help generate physiological data to determine one or more blood pressure measurements associated with the user, such as a systolic blood pressure component and / or a diastolic blood pressure component. In some embodiments, the blood pressure device 280 is a sphygmomanometer that includes an inflatable cuff that can be worn by the user and a pressure sensor (e.g., the pressure sensor 212 described herein).

[0101] In some embodiments, the blood pressure device 280 is an invasive device that can continuously monitor the arterial blood pressure of the user 20 and collect arterial blood samples as needed to analyze the gas of the arterial blood. In some other embodiments, the blood pressure device 280 is a continuous blood pressure monitor that uses a radio frequency sensor and can measure the blood pressure of the user 20 only once every few seconds (e.g., every 3 seconds, every 5 seconds, every 7 seconds, etc.). The radio frequency sensor can use continuous wave, frequency modulated continuous wave (FMCW with ramp linear frequency modulation, triangle, sine wave), other schemes such as PSK, FSK, etc., pulse continuous wave, and / or extension in ultra-wideband range (which can include extension, PRN code or pulse system).

[0102] Although the control system 200 and the memory device 204 are Figure 1 100, but in some embodiments, the control system 200 and / or the memory device 204 are integrated into the user device 260 and / or the respiratory therapy device 110. Alternatively, in some embodiments, the control system 200 or a portion thereof (e.g., the processor 202) can be located in the cloud (e.g., integrated in a server, integrated in an Internet of Things (IoT) device, connected to the cloud, subject to edge cloud processing, etc.), located in one or more servers (e.g., remote servers, local servers, etc., or any combination thereof).

[0103] Although system 100 is shown as including all of the above components, more or fewer components may be included in systems according to embodiments of the present disclosure. For example, a first alternative system includes control system 200, memory device 204, and at least one of one or more sensors 210, and does not include respiratory therapy system 100. As another example, a second alternative system includes control system 200, memory device 204, at least one of one or more sensors 210, and user device 260. As yet another example, a third alternative system includes control system 200, memory device 204, respiratory therapy system 100, at least one of one or more sensors 210, and user device 260. Thus, any portion or portions of the components shown and described herein and / or combined with one or more other components may be used to form various systems.

[0104] As used herein, a sleep session may be defined in a variety of ways. For example, a sleep session may be defined by an initial start time and an end time. In some embodiments, a sleep session is a duration of time that a user sleeps, i.e., a sleep session has a start time and an end time, and during the sleep session, the user does not wake up until the end time. That is, any period of time that the user is awake is not included in a sleep session. According to this first definition of a sleep session, if a user wakes up and falls asleep multiple times in the same night, each sleep interval separated by the wake-up interval is a sleep session.

[0105] Alternatively, in some embodiments, a sleep session has a start time and an end time, and during a sleep session, the user can be awake without the sleep session ending as long as the continuous duration of the user being awake is below an awake duration threshold. The wake duration threshold can be defined as a percentage of the sleep session. The wake duration threshold can be, for example, about 20 percent of the sleep session, about 15 percent of the sleep session duration, about 10 percent of the sleep session duration, about 5 percent of the sleep session duration, about 2 percent of the sleep session duration, etc., or any other threshold percentage. In some embodiments, the wake duration threshold is defined as a fixed amount of time, such as about one hour, about thirty minutes, about fifteen minutes, about ten minutes, about five minutes, about two minutes, etc., or any other amount of time.

[0106] In some embodiments, a sleep session is defined as the entire time between the time the user first goes to bed in the evening and the time the user last gets up the next morning. In other words, a sleep session can be defined as a period of time that starts on a first date (e.g., Monday, January 6, 2020) at a first time (e.g., 10:00 PM) when the user first goes to bed and wants to fall asleep (e.g., if the user does not plan to watch TV or use a smartphone before falling asleep, this is not the case), and ends on a second date (e.g., Tuesday, January 7, 2020) at a second time (e.g., 7:00 AM) when the user first gets out of bed and does not want to go to sleep the next morning.

[0107] In some embodiments, a user can manually define the start of a sleep session and / or manually terminate a sleep session. For example, a user can select (e.g., by clicking or tapping) a sleep session on user device 260 ( Figure 1 ) to manually initiate or terminate a sleep session by displaying one or more user-selectable elements displayed on display device 262 of the device.

[0108] Generally, a sleep session includes any point in time after the user 20 has been lying or sitting in the bed 40 (or another area or object where they intend to sleep), and has turned on the respiratory therapy device 110 and put on the user interface 120. A sleep session may therefore include the following time periods: (i) when the user 20 is using the respiratory therapy system 100, but before the user 20 attempts to fall asleep (e.g., when the user 20 is lying in the bed 40 reading a book); (ii) when the user 20 begins to try to fall asleep but is still awake; (iii) when the user 20 is in light sleep (also known as stage 1 and stage 2 of non-rapid eye movement (NREM) sleep); (iv) when the user 20 is in deep sleep (also known as slow wave sleep SWS or stage 3 of NREM sleep); (v) when the user 20 is in rapid eye movement (REM sleep); (vi) when the user 20 is awake periodically between light sleep, deep sleep, or REM sleep; or (vii) when the user 20 wakes up and does not fall back asleep.

[0109] A sleep session is generally defined as ending once user 20 removes user interface 120, turns off respiratory therapy device 110, and leaves bed 40. In some embodiments, a sleep session may include additional time periods, or may be limited to only some of the above time periods. For example, a sleep session may be defined as a time period that begins when respiratory therapy device 110 begins supplying pressurized air to the airway or user 20, ends when respiratory therapy device 110 stops supplying pressurized air to the airway of user 20, and includes some or all time points in between when user 20 falls asleep or wakes up.

[0110] refer to Figure 7 Timeline 700 in the figure, bed entry time t 床 The user initially enters the bed (e.g., before falling asleep) (e.g., when the user lies down or sits in bed) Figure 2 The bed time tbed may be identified based on the bed threshold duration to distinguish between the time when the user goes to bed to sleep and the time when the user goes to bed for other reasons (e.g., watching TV). For example, the bed threshold duration may be at least about 10 minutes, at least about 20 minutes, at least about 30 minutes, at least about 45 minutes, at least about 1 hour, at least about 2 hours, etc. Although the bed time tbed is described herein with reference to the bed, 床 , but more generally, the bed entry time tbed may refer to the time when a user initially enters any position to sleep (eg, a couch, chair, sleeping bag, etc.).

[0111] Going to sleep time (GTS) and the time it takes for the user to enter the bed (t 床 ) is associated with the time of an initial attempt to fall asleep after falling asleep. For example, after getting into bed, the user may engage in one or more activities to cool down before attempting sleep (e.g., reading, watching television, listening to music, using user device 260, etc.). The initial sleep time (t 睡眠 ) is the time when the user initially falls asleep. For example, the initial sleep time (t 睡眠 ) may be the time when the user initially enters the first non-REM sleep stage.

[0112] Wake-up time t 唤醒 The time associated with a user waking up without returning to sleep (e.g., as opposed to a user waking up and returning to sleep during the night). A user may experience multiple involuntary micro-awakenings (e.g., micro-awakening MAs) of short duration (e.g., 5 seconds, 10 seconds, 30 seconds, 1 minute, etc.) after initially falling asleep. 1 and MA 2 ) and the wake-up time t 唤醒 Instead, the user wakes up the MA in a micro 1 and MA 2 Similarly, the user may have one or more conscious awakenings (e.g., awakening A) after initially falling asleep (e.g., getting up to go to the bathroom, taking care of a child or pet, sleep walking, etc.). However, the user goes back to sleep after awakening A. Therefore, the awakening time t can be defined, for example, based on the awakening threshold duration (e.g., the user is awake for at least 15 minutes, at least 20 minutes, at least 30 minutes, at least 1 hour, etc.). 唤醒 .

[0113] Similarly, the wake-up time t 起身is associated with the time when the user wakes up and gets up to end a sleep session (e.g., as opposed to the user getting up during the night to go to the bathroom, take care of a child or pet, sleep walk, etc.). In other words, the wake-up time t 起身 is the time when the user last got up and did not return to bed until the next sleep session (e.g., the next night). Thus, the wake-up time t may be defined, for example, based on a rising threshold duration (e.g., the user has been up for at least 15 minutes, at least 20 minutes, at least 30 minutes, at least 1 hour, etc.). 起身 The bed time t of the second subsequent sleep session may also be defined based on a rising threshold duration (e.g., the user has been up for at least 4 hours, at least 6 hours, at least 8 hours, at least 12 hours, etc.). 床 time.

[0114] As mentioned above, at the initial t bed and the final t 起身 During the night between t and t, the user may wake up and get up more than once. In some embodiments, the final wake-up time t 唤醒 and / or final wake-up time t 起身 The threshold duration may be customized for the user. For a typical user who goes to bed at night and then wakes up and leaves the bed in the morning, any period between about 12 and about 18 hours (after the user wakes up (t 唤醒 ) or get up (t 起身 ) and when the user goes to bed (t 床 )、fall asleep(t GTS ) or fall asleep (t 睡眠 ). For users who spend longer periods of time in bed, a shorter threshold period (e.g., between about 8 hours and about 14 hours) may be used. The threshold period may be initially selected and / or later adjusted based on the system monitoring the user's sleep behavior.

[0115] Total time in bed (TIB) is the time to bed 床 and wake-up time 起身 Total sleep time (TST) is associated with the duration between the initial sleep time and the wake time, excluding any conscious or unconscious arousals and / or micro-awakenings in between. Typically, total sleep time (TST) will be shorter than total time in bed (TIB) (e.g., one minute shorter, ten minutes shorter, one hour shorter, etc.). For example, refer to Figure 7 The timeline 700 of the total sleep time (TST) spans the initial sleep time t 睡眠 and wake-up time t 唤醒 Between, but not including, the first micro wake-up MA 1 , the second micro wake-up MA 2and the duration of wake-up A. As shown, in this example, the total sleep time (TST) is shorter than the total time in bed (TIB).

[0116] In some embodiments, the total sleep time (TST) can be defined as the total sleep time (PTST) that is continuous. In these embodiments, the total sleep time that is continuous does not include a predetermined initial portion or period of the first non-REM stage (e.g., a light sleep stage). For example, the predetermined initial portion may be between about 30 seconds and about 20 minutes, between about 1 minute and about 10 minutes, between about 3 minutes and about 5 minutes, etc. The total sleep time that is continuous is a measure of continuous sleep and smoothes the sleep-wake sleep graph. For example, when a user initially falls asleep, the user may be in the first non-REM stage for a short time (e.g., about 30 seconds), then return to the wake stage for a short time (e.g., one minute), and then return to the first non-REM stage. In this example, the total sleep time that is continuous does not include a first example of the first non-REM stage (e.g., about 30 seconds).

[0117] In some embodiments, a sleep session is defined as a period of time between bedtime (t 床 ) and start at the wake-up time (t 起身 ) ends, that is, a sleep session is defined as total time in bed (TIB). In some embodiments, a sleep session is defined as the total time in bed (TIB) from the initial sleep time (t 睡眠 ) starts and starts at the wake-up time (t 唤醒 ) ends. In some embodiments, a sleep session is defined as total sleep time (TST). In some embodiments, a sleep session is defined as the time between sleep onset (t GTS ) starts and starts at the wake-up time (t 唤醒 ) ends. In some embodiments, a sleep session is defined as a sleep session at the time of falling asleep (t GTS ) and start at the wake-up time (t 起身 ) ends. In some embodiments, a sleep session is defined as a sleep period starting at bedtime (t 床 ) and ends at the wake time (twake). In some embodiments, a sleep session is defined as a sleep session that begins at the initial sleep time (t 睡眠 ) and start at the wake-up time (t 起身 )Finish.

[0118] refer to Figure 8 , illustrating a timeline 700 ( Figure 7). As shown, the hypnogram 800 includes a sleep-wake signal 801, a wake stage axis 810, a REM stage axis 820, a light sleep stage axis 830, and a deep sleep stage axis 840. The intersection between the sleep-wake signal 801 and one of the axes 810-840 indicates the sleep stage at a given time during a sleep session.

[0119] The sleep-wake signal 801 can be generated based on physiological data associated with the user (e.g., generated by one or more of the sensors 210 described herein). The sleep-wake signal can indicate one or more sleep states, including wakefulness, relaxed wakefulness, micro-awakening, REM stage, first non-REM stage, second non-REM stage, third non-REM stage, or any combination thereof. In some embodiments, one or more of the first non-REM stage, the second non-REM stage, and the third non-REM stage can be grouped together and classified as a light sleep stage or a deep sleep stage. For example, the light sleep stage may include the first non-REM stage, while the deep sleep stage may include the second non-REM stage and the third non-REM stage. Although the sleep graph 800 is Figure 8 800 as including a light sleep stage axis 830 and a deep sleep stage axis 840, but in some embodiments, the hypnogram 800 may include an axis for each of the first non-REM stage, the second non-REM stage, and the third non-REM stage. In other embodiments, the sleep-wake signal may also indicate a breathing signal, a breathing rate, an inspiratory amplitude, an expiratory amplitude, an inspiratory-expiratory ratio, a number of events per hour, a pattern of events, or any combination thereof. Information describing the sleep-wake signal may be stored in the memory device 204.

[0120] The hypnogram 800 may be used to determine one or more sleep-related parameters, such as, for example, sleep onset latency (SOL), wake after sleep onset (WASO), sleep efficiency (SE), sleep segmentation index, sleep blocks, or any combination thereof.

[0121] Sleep onset latency (SOL) is defined as the time to enter sleep (t GTS ) and initial sleep time (t 睡眠). In other words, the sleep start wait time represents the time it takes for the user to actually fall asleep after the initial attempt to fall asleep. In some embodiments, the sleep start wait time is defined as the continuous sleep start wait time (PSOL). The difference between the continuous sleep start wait time and the sleep start wait time is that the continuous sleep start wait time is defined as the duration between the time of entering sleep and the predetermined amount of continuous sleep. In some embodiments, the predetermined amount of continuous sleep may include, for example, sleeping for at least 10 minutes in the second non-REM stage, the third non-REM stage, and / or the REM stage, and waking up for no more than 2 minutes, the first non-REM stage, and / or the movement therebetween. In other words, the continuous sleep start wait time requires continuous sleep for up to, for example, 8 minutes in the second non-REM stage, the third non-REM stage, and / or the REM stage. In other embodiments, the predetermined amount of continuous sleep may include at least 10 minutes of sleep in the first non-REM stage, the second non-REM stage, the third non-REM stage, and / or the REM stage after the initial sleep time. In such embodiments, the predetermined amount of continuous sleep may exclude any micro-awakening (e.g., a ten-second micro-awakening does not restart a 10-minute period).

[0122] Wake after sleep onset (WASO) is associated with the total duration that the user was awake between the initial sleep time and the wake time. Thus, wake after sleep onset includes both brief awakenings and micro-awakenings during a sleep session (e.g., Figure 7 The micro wake-up MA shown 1 and MA 2 ), whether conscious or unconscious. In some embodiments, a post-sleep wake onset (WASO) is defined as a persistent post-sleep wake onset (PWASO) that includes only total durations of wakeups having a predetermined length (e.g., greater than 10 seconds, greater than 30 seconds, greater than 60 seconds, greater than about 5 minutes, greater than about 10 minutes, etc.).

[0123] Sleep efficiency (SE) is determined as the ratio of total time in bed (TIB) to total sleep time (TST). For example, if the total time in bed is 8 hours and the total sleep time is 7.5 hours, the sleep efficiency of the sleep session is 93.75%. Sleep efficiency indicates the sleep hygiene of the user. For example, if the user goes to bed before going to bed and spends time engaged in other activities (e.g., watching TV), the sleep efficiency will be reduced (e.g., the user is punished). In some embodiments, the sleep efficiency (SE) can be calculated based on the total time in bed (TIB) and the total time the user attempts to sleep. In such embodiments, the total time the user attempts to sleep is defined as the duration between the time to go to sleep (GTS) and the time to get up described herein. For example, if the total sleep time is 8 hours (e.g., 11 pm to 7 am), the time to go to sleep is 10:45 pm, and the time to get up is 7:15 am, then in such embodiments, the sleep efficiency parameter is calculated to be about 94%.

[0124] The segment index is determined based at least in part on the number of awakenings during the sleep session. For example, if a user has two micro-awakenings (e.g., Figure 7 The micro wake-up MA shown in 1 and micro wakeup MA 2 ), then the segment index can be expressed as 2. In some embodiments, the segment index is scaled between a predetermined range of integers (eg, between 0 and 10).

[0125] A sleep block is associated with a transition between any sleep stage (eg, first non-REM stage, second non-REM stage, third non-REM stage, and / or REM) and a wakeful stage. A sleep block may be calculated at a resolution of, for example, 30 seconds.

[0126] In some embodiments, the systems and methods described herein may include generating or analyzing a hypnogram including a sleep-wake signal to determine or identify a bed entry time (t 床 ), sleep time (t GTS )、initial sleep time (t 睡眠 ), one or more first micro wake-ups (eg, MA 1 and MA 2 )、Wake-up time(t 唤醒 ), wake-up time (t 起身 ) or any combination thereof.

[0127] In other embodiments, one or more of the sensors 210 may be used to determine or identify a bed entry time (t 床 ), sleep time (t GTS )、initial sleep time (t睡眠 ), one or more first micro wake-ups (e.g., MA 1 and MA 2 ), wake-up time (t 唤醒 ), getting up time (t 起身 ) or any combination thereof. For example, the bed entry time t may be determined based on data generated, for example, by the motion sensor 218, the microphone 220, the camera 232, or any combination thereof. 床 The time to go to sleep may be determined based on, for example, data from motion sensor 218 (e.g., data indicating that the user is not moving), data from camera 232 (e.g., data indicating that the user is not moving and / or the user has turned off the lights), data from microphone 220 (e.g., data indicating that the user has turned off the TV), data from user device 260 (e.g., data indicating that the user is no longer using user device 260), data from pressure sensor 212 and / or flow sensor 214 (e.g., data indicating that the user has turned on respiratory therapy device 110, data indicating that the user has put on user interface 120, etc.), or any combination thereof.

The application can recommend activities based on one or both of the sleep information of the second user 1214 and the third user 1240. The recommended activities can generally be based on the sleep information and / or the previous night's sleep of one or both of the second user 1214 and the third user 1240, as well as the effort required for the activity. For example, Fig.12 As shown, if the sleep information of one or both of the second user 1214 and the third user 1240 indicates that one or both of the second user 1214 and the third user 1240 are well rested, the recommended activity may be a physical activity (e.g., an activity requiring moderate or high exertion) such as walking, hiking, jogging, bicycle riding, etc. Fig.12, the user interface 1204 includes a recommended activity portion 1244 that includes recommended activities. Because both the second user 1214 and the third user 1240 are able to perform physical activities based on sleep information, the recommended activity portion 1244 includes a plurality of physical activities. It should be noted that in addition to sleep information, the recommended activities may also be based on personal information associated with the user.

[0139] Although Figures 9 to Fig.12 The discussion of describes determining matches for users based on sleep information, but Fig.13 The discussion of provides additional details regarding a system for determining matches for users based on sleep information.

[0140] Fig.13 1 is a block diagram of a system 1300 for determining a match based on sleep information of a user according to some embodiments of the present disclosure. System 1300 includes a control system 1302, a network 1308, and a user device 1310. In one embodiment, user device 1310 is communicatively coupled to control system 1302 via network 1308. Network 1308 can be of any suitable type (e.g., a local area network and / or a wide area network, such as the Internet). Thus, network 1308 can include wired links and / or wireless links. Although control system 1302 is depicted as a separate device, in some embodiments, the control system can reside on user device 1310. In such embodiments, user device 1310 may not need to connect to network 1308 or send data via the network.

[0141] The control system 1302 may include a fixed-purpose hardwired hardware platform (including, but not limited to, an application-specific integrated circuit (ASIC) (which is a custom integrated circuit designed for a specific purpose rather than intended for general use), a field programmable gate array (FPGA), etc.), or may include a partially or fully programmable hardware platform (including, but not limited to, a microcontroller, a microprocessor, etc.). These architectural choices for such structures are well known and understood in the art and do not require further description here. The control system 1302 is configured to perform one or more of the steps, actions, and / or functions described herein (e.g., by using corresponding programming well known to those skilled in the art).

[0142] By one optional approach, the control system 1302 is operably coupled to a memory. The memory may be integrated into the control system 1302, or may be physically separate (in whole or in part) from the control system 1302 as desired. The memory may also be local to the control system 1302 (where, for example, the two share a common circuit board, chassis, power supply, and / or housing), or may be partially or fully remote to the control system 1302 (where, for example, the memory is physically located in another facility, metropolitan area, or even country compared to the control system 1302).

[0143] The memory may be used, for example, to non-transitory store computer instructions that, when executed by the control system 1302, cause the control system 1302 to operate as described herein. As used herein, such references to "non-transitory" will be understood to refer to the non-transitory state of the stored contents (and thus excluding the case where the stored contents merely constitute a signal or wave), rather than the volatility of the storage medium itself, and thus include non-volatile memory (such as read-only memory (ROM)) as well as volatile memory (such as erasable programmable read-only memory (EPROM)).

[0144] The control system 1302 generally determines a match for a user based on sleep information. For example, the control system 1302 may receive sleep information for a user and determine a match based on the sleep information. The control system 1302 determines a match between users based on the sleep information and causes a notification to be sent based on the match.

[0145] The user device 1310 generally provides sleep information and presents the user interface of the application to the user. Therefore, the user device 1302 can be of any suitable type. For example, the user device can be a smart phone, a smart watch, a laptop or desktop computer, a personal digital assistant (PDA), a tablet computer, a car infotainment system, a smart mirror, a television, etc. In some embodiments, the user device 1310 includes an image capture device 1312, a display device 1314, a user input device 1316, and a communication radio device 1318. The image capture device 1312 can be of any suitable type (e.g., a digital camera) and is configured to capture still images and / or video images. The display device 1314 can be of any suitable type (e.g., an LED display, an LCD, etc.) and is configured to present information (e.g., instructions, a graphical user interface (GUI), images, etc.) to the user. The user input device 1316 can be of any suitable type (e.g., a keyboard, a mouse, a touch screen, a joystick, a touch pad, a microphone, etc.) and is configured to receive user input from the user. It should be noted that in some embodiments, the display device 1314 and the user input device 1316 can be combined into a single device, such as a touch screen. The communication radio device 1318 can be of any suitable type (e.g., a near field communication (NFC) radio device, a wireless wide area network (WWAN) radio device, a Wi-Fi radio device, etc.) and is configured to send data from the user device 1310 and receive data for the user device.

[0146] Although Fig.13 The discussion of provides additional details about a system for determining a match based on a user's sleep information, but Fig.14 The discussion of describes example operations of such a system.

[0147] Fig.14 is a flow chart depicting example operations for determining a match based on sleep information users according to some implementations. The process begins at block 1402 .

[0148] In block 1402, sleep information is stored. For example, a database may store sleep information. The sleep information may be associated with multiple users. The sleep information may include any suitable categories. For example, the sleep information may include sleep diagnosis (e.g., insomnia, restless legs syndrome, parasomnia, hypersomnia, circadian rhythm sleep-wake disorder), sleep schedule, sleep duration, restlessness, user device use, use of a type of sleep enhancement device, etc. In some embodiments, the sleep information may also include respiratory information. The respiratory information may include any suitable categories. For example, the respiratory information may include the use of a respiratory therapy system, the type of respiratory therapy device, the duration of respiratory therapy use (e.g., how many hours a user uses their respiratory therapy system each night), the length of time of respiratory therapy use (e.g., the time period that the user has used their respiratory therapy system, such as days, months, and / or years), sleep schedule, sleep duration, medical conditions, apnea hypopnea index, sleep score, etc. In some embodiments, the database also stores personal information of multiple users. Personal information may include any suitable categories. For example, personal information may include age, gender identity, gender, sexual orientation, location, interests, hobbies, likes, dislikes, preferences. Matching may be used for any desired relationship type. For example, the match may be based on a romantic relationship, a friendship relationship, a mentoring relationship, a mentored relationship, etc. Flow continues at block 1404 .

[0149] At block 1404, sleep information associated with the first user is received. For example, the control system may receive sleep information associated with the first user. The control system may receive the sleep information from any suitable source (e.g., a user device, a database, an external device, etc.). In some embodiments, the control system also receives personal information associated with the first user. The process continues at block 1046.

[0150] At block 1406, the sleep information is compared. For example, the control system may compare the sleep information associated with the plurality of users to the sleep information associated with the first user. Additionally, in some embodiments, the control system also compares the personal information associated with the plurality of users to the sleep information associated with the first user. In some embodiments, the control system compares the sleep information to the personal information to determine a match for the first user of the plurality of users. The process continues at block 1408.

[0151] At block 1408, a correspondence between sleep information associated with the first user and sleep information associated with multiple users is determined. For example, the control system may determine a correspondence between sleep information associated with the first user and sleep information associated with multiple users. The control system may determine the correspondence between sleep information associated with the first user and sleep information associated with multiple users based on any suitable algorithm. For example, the control system may determine the correspondence based on a match of sleep information items, a degree of sleep information match, a threshold, and the like. Additionally, in some embodiments, the correspondence may be based on weighting. For example, some categories of sleep information may be weighted more heavily than other categories. The weighting may be done automatically and / or based on user input indicating the desired importance of some or all categories. The process continues at block 1410.

[0152] At block 1410, a notification is generated. For example, the control system may generate a notification. The control system generates the notification based on a correspondence between sleep information associated with a first user and sleep information associated with one or more of a plurality of users. For example, if the control system determines a correspondence between sleep information associated with a first user and sleep information associated with a second user, the control system generates a notification based on the correspondence between sleep information associated with the first user and sleep information associated with the second user. The notification indicates that the application has found a match for the first user. The notification may include any suitable information (e.g., identification of one or more users, sleep information, breathing information, search criteria, personal information, etc.). The process continues at block 1412.

[0153] At block 1412, a notification is sent. For example, the control system may send the notification via a communication network. The control system may send the notification to one or both of the first user and the second user.

[0154] The matching application can be a standalone application of the user device. Alternatively, the matching application can be an "opt-in" addition to a pre-existing engagement application that accompanies the user device or an external device (e.g., a sleep enhancement device or respiratory therapy device, a sleep monitoring device, etc.).

[0155] One or more elements or aspects or steps from one or more of any one of the following claims 1 to 27, or any portion thereof, may be combined with one or more elements or aspects or steps from one or more of any one of the other claims 28 to 55, or any portion thereof, or a combination thereof to form one or more additional embodiments and / or claims of the present disclosure.

[0156] Although the present disclosure has been described with reference to one or more specific embodiments or implementations, those skilled in the art will recognize that many changes may be made thereto without departing from the spirit and scope of the present disclosure. Each of these embodiments and their obvious variations are contemplated to fall within the spirit and scope of the present disclosure. It is also contemplated that additional embodiments according to aspects of the present disclosure may combine any number of features from any of the embodiments described herein.
