[0032] Figure 3 is a graph showing experimental CO2 readings measured during CO2 insufflation. DETAILED DESCRIPTION
[0033] In the following description, various aspects of the present disclosure will be described. For the purpose of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the different aspects of the present disclosure. However, it is also apparent to those skilled in the art that the present disclosure may be practiced without the specific details presented herein. In addition, well-known features may be omitted or simplified in order to avoid confusing the present disclosure.
[0034] According to some embodiments, a carbon dioxide concentration monitoring system is provided, which includes a CO2 sensing module and a piping system. The CO2 sensing module includes a CO2 sensor configured to measure the CO2 concentration in the exhaled breath of a subject, a processing unit configured to derive one or more breathing-related parameters based on the measured CO2 concentration, a pump, and a communication unit. The piping system is configured to allow respiratory gas to flow therethrough, and includes a connector configured to connect the piping system to the CO2 sensing module, and a communication component configured to provide an indication of the type of the connected piping system to the communication unit. The communication unit is configured to transmit data to the processing unit based on the indication obtained from the communication component. The processing unit uses the transmitted data to change or suggest changing the operating mode of the CO2 sensing module based on the transmitted data.
[0035] Advantageously, the carbon dioxide concentration monitoring system disclosed herein enables communication in two directions, optionally between a tubing system and a CO2 sensing module connected thereto. This enables one to specify and / or customize the operating mode of the CO2 sensing module according to the connected tubing system and / or its medical application, by implementing sample line specific algorithms and / or features based on the type of consumable connected.
[0036] According to some embodiments, the communication component may be configured to store, receive and / or transmit data. Each possibility is an independent embodiment.
[0037] According to some embodiments, the communication component may be further configured to provide a second indication of a characteristic of the pipeline system, such as, but not limited to, the length of the sampling tube, the diameter of the pipeline system, the target population of the pipeline system, the expected duration of use of the pipeline system, or any combination thereof. Each possibility is an independent embodiment. According to some embodiments, the processing unit may be further configured to adjust or suggest adjusting the operating mode of the CO2 sensing module based on the second indication.
[0038] As a non-limiting example, in upper gastrointestinal surgeries requiring the use of a bite block, a common problem is that CO2 concentration measurements always spike due to the patient's insufflation with CO2. Communication between the bite block conduit and the CO2 sensing module can advantageously enable customization of the CO2 sensing module's operating mode to implement an algorithm that enables spikes to be ignored and / or identified as artifacts caused by insufflation, thereby preventing or reducing the triggering of nuisance alarms.
[0039] Similarly, in an emergency (EMS) where a patient is intubated, the presence of a CO2 reading is often used to verify that the intubation is correct. However, when using sidestream carbon dioxide concentration monitoring, the longer response time due to the passage of the breath sample through the sampling tube may delay the verification time, which may be critical in the case where reintubation is required. The communication between the intubation and the CO2 sensing module can advantageously enable the customization of the operating mode of the CO2 sensing module, thereby triggering an increase in the pumping speed until the first reading is obtained, thereby significantly reducing the response time, and therefore reducing the time required to verify the correct intubation. It should be noted that the increase in pumping speed may only apply to adult intubation. Therefore, the communication component (whether the same or different component) can additionally provide data on the characteristics of the connected pipeline, such as the intubation is used for adults or neonates, and only triggers the increase in pumping speed when the intubation for adults is connected.
[0040] As an additional example, in general care unit (GCF) and / or post-operative settings, patients experiencing pain and / or undergoing pain management may experience elevated respiratory rates that, while interpretable as unrelated to pathological breathing, often result in unnecessary triggering of alarms. Communication between the breath sampling tube and the CO2 sensing module may advantageously enable customization of the CO2 sensing module's operating mode to implement an algorithm that enables elevated respiratory rates to be ignored and / or identified as artifacts, thereby preventing / reducing triggering of nuisance alarms.
[0041] According to some embodiments, adjustments and / or changes to the operating mode of the CO2 sensing module may be automatically activated by connecting a specific conduit to the CO2 sensing module without any user intervention or changes to the host monitor design. Alternatively, sample line specific algorithms and / or features may take the form of recommendations (e.g., presented to the user on a display of the UI), and implementation of the algorithms and / or features may require user consent. By allowing user feedback, the user may discard / reject change recommendations or modify change recommendations based on the user's professional perception / judgment of the patient's needs.
[0042] According to some embodiments, the data may be encrypted. As a non-limiting example, data transmitted from the communication unit to the processing unit and / or the remote computing unit may be encrypted, and data transmitted from the processing unit and / or the remote computing unit to the communication unit may be encrypted to ensure that the data is not interfered with by the user.
[0043] According to some embodiments, the communication component may be further configured to provide a third indication of manufacturing details of the pipeline system to the communication unit. Non-limiting examples of suitable manufacturing details include production site, production date, production location, batch number, serial number, expiration date, or any combination thereof. Each possibility is an independent embodiment.
[0044] According to some embodiments, the communication unit may be further configured to transmit a third indication about manufacturing details to a remote computing unit for storage and / or further analysis. It should be understood that the remote computing unit may use the transmitted data for quality control analysis. As a non-limiting example, the remote computing unit may be programmed by software to analyze the manufacturing quality of the manufacturing site by correlating the performance of the pipeline system with a specific manufacturing site. As another non-limiting example, the remote computing unit may be programmed by software to identify the pipeline system belonging to a batch with manufacturing defects by correlating the performance of the pipeline system with the manufacturing site. As another non-limiting example, the remote computing unit may be programmed by software to manage production and / or storage parameters by monitoring the serial number, batch number and / or expiration date of the pipeline system used. According to some embodiments, the remote unit may transmit user instructions back to the user interface (user-interphase) based on the quality control analysis. For example, once a defective batch is identified, a blockage in the pipeline system belonging to the defective batch may cause a pop-up message on the host monitor to notify the user of the defect, optionally popping up together with a suggestion to abandon the pipeline system. Additionally or alternatively, the remote unit and / or user interface may transmit data back to the communication component of the pipeline system itself. As a non-limiting example, a blockage in an outdated pipeline system may result in automatic disposal / termination of the availability of the pipeline system, preventing misuse. As another non-limiting example, a blockage in an outdated pipeline system may result in deactivation of the CO2 sensing module. According to some embodiments, a blockage in an outdated pipeline system may result in the communication component of the pipeline system sending a notification to the CO2 sensing module and / or to a host monitor.
[0045] According to some embodiments, the communication component may be further configured to transmit usage data (also referred to herein as performance data) to the communication unit and / or processing unit of the CO2 sensing module. Non-limiting examples of suitable usage data include the number of blockages of the pipeline system, the duration of use, the number of uses / connections of the pipeline system to the CO2 sensing module, or any combination thereof. Each possibility is an independent embodiment. According to some embodiments, the communication unit may be further configured to transmit the usage data to a remote computing unit (and / or user interface) for storage and / or further analysis. According to some embodiments, the remote computing unit may use the performance data for quality control analysis. As a non-limiting example, the remote computing unit may be programmed by software to analyze the manufacturing quality of the manufacturing site by correlating the performance of the pipeline system with a specific manufacturing site.
[0046] According to some embodiments, the communication unit may control the use of the pipeline data based on the transmitted performance data during use. As a non-limiting example, the pipeline system or CO2 sensing module may include a pressure sensor configured to detect pressure changes in the pipeline system, the pressure changes caused by blockage / blockage in the pipeline system. According to some embodiments, once the pipeline is identified to be repeatedly blocked / blocked, the communication unit of the CO2 sensing module may be configured to transmit / trigger a message to pop up on the host monitor, notifying the user that the pipeline system has reached a saturated state, optionally together with a suggestion to abandon the pipeline system. In addition or alternatively, the communication unit may transmit data back to the communication component to cause it to be abolished and / or change its state to prevent misuse. As another non-limiting example, the communication component may be configured to transmit the duration of use to the communication unit. Then, once the upper limit of use is reached and / or approached, the communication unit may trigger a message to pop up on the host monitor, notifying the user that the pipeline system has reached a saturated state, optionally together with a suggestion to abandon the pipeline system. Additionally or alternatively, once the usage limit is reached, the communication unit may transmit data back to the communication component causing it to disable / terminate its availability and / or change its status, thereby preventing further use of the pipeline system in a potentially dangerous situation.
[0047] According to some embodiments, abandoning, disposing, abolishing and terminating the availability of the pipeline system may include damaging the communication components of the pipeline system, thereby preventing it from being recognized by the CO2 sensing module. According to some embodiments, abandoning, disposing, abolishing and terminating the availability of the pipeline system may include changing the state (e.g., the pipeline is blocked), and the change of state can be recognized by the CO2 sensing module. According to some embodiments, the change of state may cause / trigger the CO2 sensing module to notify the host monitor of the changed state. According to some embodiments, the change of state may deactivate the CO2 sensing module. According to some embodiments, the change of state may cause / trigger the CO2 sensing module to notify the host monitor of the changed state.
[0048] According to some embodiments, the communication link may include or may be a communication bus, such as a serial communication bus. According to some embodiments, the serial communication bus may be a single-wire bus. According to some embodiments, the serial communication bus may be an EEPROM, such as but not limited to a single-wire EEPROM. According to some embodiments, the serial communication bus may be an inter-integrated circuit (I2C) bus, a universal asynchronous receiver-transmitter (UART) bus, a serial peripheral interface (SPI) bus, etc. According to some embodiments, the communication link may include near field communication (NFC) or radio frequency identification (RFID).
[0049] According to some embodiments, the communication unit facilitates a bus communication protocol. According to some embodiments, the communication unit facilitates a master / slave communication protocol, wherein the communication component in the consumable is a slave communication component and the communication unit of the CO2 sensing module is a master communication controller. According to some embodiments, the communication unit is configured to manage communications over the communication component.
[0050] Reference now Figure 1 , which schematically illustrates a functional block diagram of a carbon dioxide concentration monitoring system 100 according to some embodiments. According to some embodiments, the carbon dioxide concentration monitoring system 100 includes a communication component 102 that communicates with a CO2 sensing module 104 (e.g., a CO2 sensing system).

According to some embodiments, the CO2 sensing module 104 is further configured to transmit data to the host monitor 106 and / or the remote computing unit 108 based on the received indication. According to some embodiments, the CO2 sensing module 104 is configured to trigger a user notification message 114 on the host monitor 106 based on the identified desired clinical application, notifying the user about the operating mode suggestion or the current operating mode or the change / adjustment of the operating mode.

[0053] According to some embodiments, the CO2 sensing module 104 is configured to be used for consumable authentication 116 based on the manufacturing details of the pipe system 118 connected thereto received from the communication component 102. For the purpose of authentication, the manufacturing details may include at least one of the production site, production date, production location, batch number, serial number, expiration date, any combination thereof, or any other identification mark. According to some embodiments, once the manufacturing details of the pipe are not authenticated / identified, the CO2 sensing module 104 may be configured to terminate or suggest terminating the availability of the pipe system. Alternatively, if authentication is not performed, the CO2 sensing module 104 may not be able to start. Additionally or alternatively, the CO2 sensing module 104 may transmit data back to the communication component 102, thereby revoking / terminating its availability and / or changing its state when the authentication is not confirmed, thereby preventing the use of incompatible pipe systems in potentially dangerous situations. According to some embodiments, the CO2 sensing module 104 is additionally configured to transmit data based on the consumable authentication 116 to host the monitor 106 and / or the remote computing unit 108. According to some embodiments, the CO2 sensing module 104 is configured to trigger the display of a user notification message 114 on the host monitor 106, notifying the user of the authentication result, and optionally, in the event of a problem with the authentication, together with a message to terminate the use or suggest the termination of the use. According to some embodiments, the user is allowed to implement, adjust or overrule the termination of the use suggestion.

[0068] Examples
[0069] Reference is now made to the following examples, which together with the above descriptions illustrate embodiments in a non-limiting fashion.
[0070] Example 1
[0071] A trial was conducted to evaluate the efficiency and / or effectiveness of using a communication component to indicate the use of a capnography system during a CO2 insufflation procedure, thereby customizing the operation of the capnography system to reduce nuisance EtCO2 alarms during insufflation. To this end, a CO2 sensing module was configured to include an algorithm capable of identifying and filtering out artifacts in CO2 concentrations resulting from insufflation of CO2 (rather than respiratory complications), specifically for upper gastrointestinal procedures utilizing a tube containing a bite block. Figure 3 As shown, the improved CO2 sensing module is able to identify the spike as an artifact, thus confirming its suitability for use in an operating mode tailored for upper gastrointestinal surgery, thereby reducing the triggering of nuisance alarms.
[0072] It should be noted that initial identification of the duct system may be critical and / or useful before applying the algorithm. For example, filtering artifacts during data processing may not provide ideal accuracy without prior identification of the duct system.
[0073] Example 2
[0074] Experiments were conducted to evaluate the efficiency and / or effectiveness of using a communication component to indicate the use of a carbon dioxide concentration monitoring system in an emergency (EMS) situation in order to reduce the time required to verify correct intubation. Customizing the operating mode of the carbon dioxide concentration monitoring system to include the communication component disclosed herein reduced the average time to verify correct intubation by approximately 25% and 12%, regardless of the length of the tubing. As in other electromechanical devices, the pump in the carbon dioxide concentration monitoring module is generally designed to operate at an optimal point / near an optimal point below its full load capacity. This can be the best efficiency point of the pump, or it can be set according to the need to reduce the size of the pump or minimize the acoustic noise generated by the pump. Because the pump cannot operate at full load capacity under normal conditions, it is possible to increase the output of the pump, thereby increasing the flow rate of the sampled air, thereby shortening the response time. It is allowed to increase the output of the pump to its maximum limit (e.g., upper limit) within a short time interval; however, continuously operating the pump at the maximum output limit of the pump may have an adverse effect on the operation of the system (e.g., safety, wear). In addition, increasing the flow rate of the sampled air may not be suitable for certain patient groups, such as newborns. Thus, the system's ability to identify a tubing system and activate a "maximum pump output" feature only when a tubing system intended for use with certain types of patients (eg, adult patients) is identified may provide various advantages.
