Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to a method and system for suggesting settings of an alarm threshold, and a monitor. Background Art

[0002] Monitoring equipment is connected to patients and is used to monitor their physiological parameters. During use, if the monitored physiological parameters exceed a pre-set threshold range, the monitoring equipment will issue an alarm to inform the monitor of the patient's physiological condition. However, in some cases, such as due to different patient symptoms or due to the differences in normal physiological parameters of each patient, the monitoring parameters may frequently exceed the pre-set threshold, such as fluctuating above and below the threshold, even though the patient's condition remains normal or has not reached the level that requires an alarm to alert the monitor. Therefore, the monitor cannot distinguish between truly clinically significant alarms and non-clinical alarms from these frequent alarms. As a result, a large number of meaningless alarms lead to alarm fatigue. Currently, the problem of alarm fatigue has been listed as a medical injury for many years. The large number of meaningless alarms reduces the monitor's sensitivity, thereby posing clinical risks. Summary of the Invention

[0022] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0023] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0024] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0025] The present invention mainly involves analyzing the monitoring data generated by the monitor, analyzing whether the alarm threshold associated with the current monitoring parameters needs to be adjusted, and generating and displaying threshold setting suggestion information for user reference. Figure 1 As shown, the monitoring system provided by the present invention includes a processor 20, a display 40 and an input device 50.

[0026] The input device 50 is configured to receive input from a user (usually an operator), and may be, for example, one or more of a mouse, keyboard, trackball, and joystick to receive user input commands, etc. The user can perform input operations through the input device 50 .

[0027] The display 40 is configured to output information, such as visual information. The display 40 and the input device 50 are human-computer interaction devices of the monitoring system, which can also be a touch display that can both receive user input commands and display visual information.

[0028] Processor 20 is configured to obtain patient monitoring data, where the monitoring data includes at least one of condition information, monitoring parameter information, parameter alarm information, and user interaction information. The monitoring data can be obtained from the patient monitor. Based on the monitoring data, processor 20 determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted. The alarm threshold can be an upper threshold and / or a lower threshold. For example, a heart rate typically cannot be too high or too low, so it has an upper and lower threshold. The upper threshold indicates that a monitoring parameter value exceeding the upper threshold is considered abnormal and triggers an alarm. The lower threshold indicates that a monitoring parameter value falling below the lower threshold is considered abnormal and triggers an alarm. A monitoring parameter can be associated with only one alarm threshold, i.e., the alarm threshold is specific to that monitoring parameter and not to other monitoring parameters. The numerical units of this alarm threshold are typically the same as those of the monitoring parameter. Of course, clinical diseases are complex, and the values ​​of multiple monitoring parameters may fall within a specific range, indicating a worsening of the patient's condition and requiring an alarm. Therefore, monitoring parameters can be associated with multiple alarm thresholds, including one associated with only one monitoring parameter, as described above, and another associated with multiple monitoring parameters. The alarm threshold related to multiple monitoring parameters can be, for example, a value obtained by weighted calculation of the values ​​of the multiple monitoring parameters.

[0029] If the current alarm threshold associated with the monitoring parameter needs to be adjusted, the processor 20 generates threshold setting recommendation information based on the monitoring data and the current alarm threshold associated with the monitoring parameter; and controls the display 40 to output the threshold setting recommendation information, for example, controlling the display 40 to display the threshold setting recommendation information. This threshold setting recommendation information may include a recommended alarm threshold for adjustment for the user's reference. This not only prompts the user to adjust the alarm threshold, but also provides a recommended alarm threshold for the user's reference, which helps alleviate alarm fatigue.

[0030] The monitoring system provided by the present invention can be a monitor (e.g., a bedside monitor), a central station (e.g., a central monitoring system), etc. This embodiment uses a monitor as an example for description. In this embodiment, the monitor also includes a sensor 10, an alarm device 30, and a storage device (not shown).

[0031] The storage device is used to store monitoring data.

[0032] Sensor 10 is used to monitor a patient's physiological parameters and obtain monitoring parameter information. Monitoring parameter information includes at least one of the following: monitoring parameter type (e.g., one or more of electrocardiogram (ECG), respiration, non-invasive blood pressure (NIBP), blood oxygen saturation (O2), pulse, body temperature, invasive blood pressure, end-tidal CO2, respiratory mechanics, anesthetic gas, cardiac output, and bispectral index), monitoring parameter value, monitoring parameter value trend, and parameter alarm on / off status. This embodiment uses the aforementioned four types as an example for explanation. The monitoring parameter value trend can reflect whether the patient's condition is worsening or remaining relatively stable, and the parameter alarm on / off status can reflect the medical staff's level of attention to the monitoring parameter. Therefore, using this information as a basis for determining whether to adjust the alarm threshold and as a basis for generating a recommended alarm threshold can improve the accuracy of the judgment.

[0033] The alarm device 30 is used to issue a parameter alarm to notify the user that the monitored parameter value has deviated from the alarm threshold. The device may include a buzzer, a speaker, an indicator light, and / or a display. For example, a buzzer or speaker may emit an alarm sound, an indicator light may flash, and a display may display the parameter alarm in a prominent color, brightness, or font size, all of which can notify the user of abnormal monitored parameter values.

[0034] Correspondingly, the processor 20 is also configured to compare the monitoring parameter value in the monitoring parameter information with the current alarm threshold associated with the monitoring parameter. In the case where one alarm threshold is associated with one monitoring parameter, the values ​​can be directly compared; in the case where one alarm threshold is associated with multiple monitoring parameters, the values ​​of the associated multiple monitoring parameters are calculated according to a preset rule and then compared with the alarm threshold. The processor 20 controls the alarm device 30 to issue a parameter alarm based on the comparison result; in this process, the processor 20 can record the parameter alarm information. The parameter alarm information includes at least one of the number of monitoring parameter alarms, the duration of the monitoring parameter alarm, the alarm priority, and the sound and light settings of the monitoring parameter alarm. This embodiment is described by taking the above four as an example. The alarm priority is usually which alarm is output first when there are multiple alarms. The sound and light settings of the monitoring parameter alarm can be the volume of the alarm sound, the frequency, color or brightness of the flashing indicator light, etc., or the color, brightness or font size of the content displayed on the display.

[0035] In the daily monitoring process, the size of the alarm threshold directly determines the frequency of the alarm (frequency, frequency), that is, the number of alarms per unit time. The monitoring system of the present invention can provide setting suggestions for the monitoring parameter alarm threshold, and the process is as follows: Figure 2 As shown, the following steps are included:

[0036] Step 1: Processor 20 obtains patient monitoring data. For example, the monitoring data is stored in a storage device of a patient monitor, and processor 20 can obtain the monitoring data from the storage device. Sensor 10 generates monitoring parameter information by monitoring the patient's physiological parameters, and processor 20 can also obtain the monitoring parameter information from sensor 10. The monitoring data may include at least one of condition information, monitoring parameter information, and parameter alarm information. The monitoring data may also include user interaction information. This embodiment is described using the example of condition information, monitoring parameter information, parameter alarm information, and user interaction information.

[0037] The medical condition information includes at least one of personal characteristic information, disease diagnosis information, nursing medication records, treatment plans, and electronic medical records. This embodiment uses the above five types of information as an example for illustration. Personal characteristic information includes at least one of the patient's age, height, weight, and gender. This embodiment uses the above four types of information as an example for illustration. Medical condition information may be generated during the doctor's examination, diagnosis, and treatment of the patient. The processor 20 can obtain medical condition information from other medical systems and medical devices connected to the monitoring system network. Of course, medical condition information can also be manually entered into the system by doctors or nurses.

[0038] User interaction information includes at least one of the following: the alarm conditions of monitoring parameters set by the user during the monitoring period; the user's operation to turn on or off the monitoring parameter alarm switch; the number and / or frequency of monitoring parameter alarms handled by the user (number and frequency are essentially the same thing); and the user's response time to monitoring parameter alarms. This embodiment uses the above four types of information as an example for description. The processor 20 can obtain user interaction information based on the interactive interface displayed on the display 40 and the user's input received by the input device 50. The alarm condition can be an alarm threshold, or it can also be a condition such as which monitoring parameter values ​​reach which range to trigger an alarm.

[0039] In step 2, the processor 20 determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the monitoring data. If so, the processor 20 generates threshold setting recommendation information based on the monitoring data and the current alarm threshold associated with the monitoring parameter. Otherwise, the processor returns to step 1. For example, the processor 20 determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on at least one of the condition information, monitoring parameter information, parameter alarm information, and user interaction information. If so, the processor 20 generates threshold setting recommendation information based on the current alarm threshold associated with the monitoring parameter and at least one of the corresponding condition information, monitoring parameter information, parameter alarm information, and user interaction information to reduce the frequency of parameter alarms. For example, if certain conditions are inherently accompanied by abnormalities in certain monitoring parameters, the number of alarms for such monitoring parameters can be reduced.

[0040] Step 3: The processor 20 outputs threshold setting recommendation information, for example, by displaying the threshold setting recommendation information on the display 40 for the user's reference. The threshold setting recommendation information may include a recommended alarm threshold value for adjustment. Upon viewing the recommended alarm threshold value, the user will know that the current alarm threshold needs to be adjusted and can directly adopt the recommended alarm threshold value as the new alarm threshold value. Alternatively, the user may simply refer to the recommended alarm threshold value and ultimately adjust the current alarm threshold based on their own judgment. While displaying the threshold setting recommendation information, the current alarm threshold value associated with the monitoring parameter, the trend of change in the monitoring parameter value (e.g., increasing, decreasing, or essentially stable) may also be displayed for the user's reference. The threshold setting recommendation information and the current alarm threshold value may be displayed directly, or when the input device 50 receives a user request for threshold setting recommendation (e.g., when receiving a user instruction to adjust the current alarm threshold value associated with the monitoring parameter), the threshold setting recommendation information and the current alarm threshold value may be displayed, allowing the user to confirm the recommended alarm threshold value or modify the current alarm threshold value based on the recommended alarm threshold value. The threshold setting recommendation information may also include recommendations for increasing or decreasing the current alarm threshold value. The threshold setting recommendation information may also include information recommending lowering the alarm priority. Threshold setting suggestion information can also include information suggesting adjustments to the audio and visual settings of monitoring parameter alarms. For example, it can suggest reducing the alarm volume, reducing the flashing frequency of the indicator light, dimming the indicator light brightness, etc., to reduce alarm fatigue. This can also alleviate alarm fatigue to a certain extent.

[0041] Specifically, the processor 20 can display an alarm threshold adjustment area on the display interface of the display 40 for the user to perform input operations. The content displayed in the alarm threshold adjustment area includes at least one of the recommended alarm threshold associated with the monitoring parameter, the option to support the user to set the alarm threshold, or the option to confirm the recommended alarm threshold. This embodiment is described by taking the above three as an example. In this way, if the user feels that the alarm threshold recommended by the system is appropriate, the modification of the alarm threshold can be completed by confirming the recommended alarm threshold through the input device 50. That is, after the input device 50 receives the user's confirmation instruction, the processor 20 uses the recommended alarm threshold as the current alarm threshold associated with the corresponding monitoring parameter. If the user feels that the recommended alarm threshold recommended by the system needs to be slightly adjusted, the alarm threshold can be adjusted through the option to support the user to set the alarm threshold. That is, after the input device 50 receives the user's input operation, the processor 20 adjusts the current alarm threshold associated with the monitoring parameter according to the user's input operation.

[0042] Different monitoring data may have different ways of determining whether the current alarm threshold associated with the monitoring parameter needs to be adjusted. For example, the processor 20 retrieves a preset field in the condition information of the monitoring data. The preset field can be a field reflecting the disease, such as respiratory failure, hypertension, hyperlipidemia, etc. If the preset field is retrieved, it means that the patient has the corresponding disease, and the corresponding monitoring parameter value is too high or too low. The doctor usually already knows this situation, so the number of alarms needs to be reduced. That is, the processor 20 determines that the current alarm threshold of the monitoring parameter associated with the preset field needs to be adjusted. The preset field can be set as needed. For example, the preset field can be a preset field reflecting the patient's diagnostic information. The processor 20 retrieves the preset field reflecting the patient's diagnostic information from the condition information of the monitoring data, and determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the disease type corresponding to the retrieved preset field. If the preset field is retrieved, it is determined that the current alarm threshold needs to be adjusted. If the preset field is not retrieved, it is determined that no adjustment is required. Taking the preset field of "respiratory failure" as an example, the processor 20 obtains the patient's condition information and retrieves "respiratory failure" from the patient's condition information. If "respiratory failure" is retrieved, it is determined that the current alarm thresholds of monitoring parameters such as respiration and blood oxygen saturation need to be adjusted. If "respiratory failure" is not retrieved, it is confirmed that the current alarm thresholds of respiration, blood oxygen saturation, etc. do not need to be adjusted.

[0043] For another example, the processor 20 obtains the monitoring parameter value within a preset first time period from the monitoring parameter information of the monitoring data, obtains the cumulative time that the monitoring parameter is within the preset first range based on the monitoring parameter value within the first time period, and determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the cumulative time. The first range can be a range indicating that the monitoring parameter value is close to the alarm threshold. For example, if the cumulative time exceeds a preset time, it is considered that the monitoring parameter value is close to the current alarm threshold and needs to be adjusted; if the cumulative time does not exceed the preset time, it is considered that the monitoring parameter value is not close to the current alarm threshold and does not need to be adjusted. The specific values ​​or intervals of the first time period and the first range are set as needed. In one specific application, the processor 20 obtains monitoring parameter information, such as the patient's heart rate (HR) per second over the past hour, and determines whether the HR value is close to the alarm threshold. The determination method is as follows: the threshold proximity limit (i.e., the first range) is calculated, where the upper limit = the high HR alarm limit - 5 bpm and the lower limit = the low HR alarm limit + 2 bpm. If the HR value ≥ the upper limit, the current HR value is considered close to the upper alarm limit; if the HR value ≤ the lower limit, the current HR value is considered close to the lower alarm limit. The processor 20 then calculates the accumulated time t1 and t2 of the patient's heart rate close to the upper alarm limit over the past hour. If t1 ≥ 30 minutes, the heart rate is considered "close to the upper alarm limit"; otherwise, it is considered "close to the lower alarm limit." Of course, in addition to accumulated time, other methods can also be used to determine whether the monitoring parameter value is close to the alarm threshold. For example, the processor 20 obtains the monitoring parameter value within a preset first time period from the monitoring parameter information of the monitoring data, obtains the number of monitoring parameter values ​​within the preset first range based on the monitoring parameter value within the first time period, and judges whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the number. Specifically, if the number exceeds a preset number, it is determined that the monitoring parameter value is close to the alarm threshold and the current alarm threshold needs to be adjusted; otherwise, the current alarm threshold does not need to be adjusted.

[0044] For another example, the processor 20 obtains the number of monitoring parameter alarms within a preset second time period from the parameter alarm information of the monitoring data, and determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the number of monitoring parameter alarms within the second time period. The second time period can be the same as or different from the first time period and is set as needed. Specifically in one application, the processor 20 obtains the number of "high heart rate" alarms (the number of times the heart rate exceeds the alarm threshold) within the past hour from the parameter alarm information. If the high heart rate alarm has occurred 5 times in total within the past hour, and at least one high heart rate alarm has occurred in the last 15 minutes, it is considered that the current high heart rate is "frequently alarmed", and it is determined that the high heart rate alarm threshold needs to be adjusted.

[0045] For another example, the processor 20 obtains the number and / or frequency of user processing of monitoring parameter alarms within a preset third time period from user interaction information of the monitoring data, and determines whether the current alarm threshold associated with the corresponding monitoring parameter needs to be adjusted based on the number and / or frequency of user processing of monitoring parameter alarms within the third time period. In one application, the processor 20 obtains the number of times the monitor alarm mute button is clicked within a period of time, such as 20 minutes, from the user interaction information. If this number exceeds a preset number, it determines that the current alarm threshold associated with the corresponding monitoring parameter needs to be adjusted.

[0046] Of course, the parameter alarm information and user interaction information can also be combined to comprehensively determine whether the current alarm threshold needs to be adjusted. For example, if the processor 20 obtains that the user has a high heart rate alarm three times within a period of time, such as the past 20 minutes, and the user has clicked the alarm mute button three times, the high heart rate alarm is considered a "meaningless alarm" and determines that the high heart rate alarm threshold needs to be adjusted. The alarm mute button is a button that silences the alarm of the alarm device 30.

[0047] The processor 20 determines whether the current alarm threshold associated with the monitoring parameter needs to be adjusted based on the user interaction information. For example, when the user interaction information received by the input device 50 includes a user instruction to adjust the current alarm threshold associated with the monitoring parameter, the processor 20 determines that the current alarm threshold associated with the monitoring parameter needs to be adjusted. For example, the input device 50 may also include a camera, a microphone, etc. The camera may detect a caregiver (doctor, nurse, etc.) viewing the monitoring device through facial recognition, thereby determining that the current alarm threshold associated with the monitoring parameter needs to be adjusted. The microphone may also capture sound, and the processor 20 may process the sound captured by the microphone and recognize the caregiver's complaint about the alarm through the sound, thereby determining that the current alarm threshold associated with the monitoring parameter needs to be adjusted. If the processor 20 determines that the current alarm threshold associated with the monitoring parameter needs to be adjusted, it may obtain the expected change in the number of parameter alarms from the user interaction information. For example, if the user frequently handles monitoring parameter alarms, it may indicate that the user desires to reduce the number of alarms. Based on the expected change in the number of parameter alarms and the current alarm threshold associated with the monitoring parameter, the processor 20 generates a recommended alarm threshold associated with the monitoring parameter to meet the expected change in the number of parameter alarms. The user interaction information directly reflects the user's expectation, which may require reducing the number of alarms. That is, the expectation of changing the number of parameter alarms at least includes reducing the frequency of parameter alarms.

[0048] The processor 20 may generate a recommended alarm threshold associated with the monitoring parameter based on the monitoring data and the current alarm threshold of the monitoring parameter, which may include: if the alarm threshold is an upper threshold, calculating the mean of the monitoring parameter values ​​within a predetermined fourth time period, comparing the mean with the current alarm threshold, and increasing the larger of the two values, for example, by increasing the larger value by a predetermined value, and using the increased value as the recommended alarm threshold. The fourth time period and the predetermined value may be set as needed. For example, the processor 20 may obtain the upper alarm threshold corresponding to the target alarm, such as the upper heart rate alarm threshold for a high heart rate, which is generally 120 bpm. To calculate the recommended alarm threshold, the processor 20 may calculate the mean of the heart rate over the last 15 minutes and take the larger of (mean heart rate + 10 bpm) and (high heart rate alarm threshold + 10 bpm) as the recommended alarm threshold. Similarly, if the alarm threshold is a lower threshold, the processor 20 may calculate the mean of the monitoring parameter values ​​within the predetermined fourth time period, compare the mean with the current alarm threshold, and decrease the smaller of the two values, for example, by decreasing the smaller value by a predetermined value, and using the decreased value as the recommended alarm threshold.

[0049] In one specific application, for example, if a patient with respiratory failure on a ventilator frequently or continuously experiences low blood oxygen level alarms within a preset first time period, such as one hour, the blood oxygen level alarm threshold can be adjusted within a certain range (e.g., a preset value) based on the blood oxygen level during this period, and a threshold setting recommendation can be provided to prevent or significantly reduce low blood oxygen level alarms. For example, if a patient frequently or continuously experiences high heart rate alarms within a period, such as one hour, or if the heart rate consistently approaches the upper heart rate threshold within a certain range, the heart rate alarm threshold can be adjusted within a certain range based on the heart rate values ​​during this period, and a threshold setting recommendation can be provided to prevent or significantly reduce high heart rate alarms. For example, if a patient frequently or continuously experiences high PVCs (premature ventricular contractions) alarms within a period, such as one hour, the PVCs alarm threshold can be adjusted within a certain range based on the number of PVCs and their changing trend during this period, and a threshold setting recommendation can be provided to prevent or significantly reduce high PVCs alarms.

[0050] In summary, the monitoring system and method provided by the present invention determine whether the current alarm threshold associated with the monitoring parameter needs to be adjusted, and intelligently recommend threshold adjustment strategies to assist users in optimizing the alarm threshold and other operations, thereby reducing meaningless over-limit alarms, alleviating alarm fatigue problems, and reducing the harm caused by excessive alarms.
