The present application claims the benefit of priority of Japanese Patent Application No. 2023-069941, filed on Apr. 21, 2023, the content of which is incorporated herein by reference.
The presently disclosed subject matter relates to an alarm control system, an alarm control method, and a non-transitory computer-readable storage medium storing an alarm control program.
In a patient monitor that displays the physiological information of a patient or the like, there has been a technique of outputting a physiological alarm (vital alarm) that notifies an abnormality detected in the physiological information or a device alarm (technical alarm) that notifies an abnormality related to the state of a medical device or a system that measures the physiological information.
When an alarm is notified, the medical staff or the like checks and deals with the contents of the alarm. For example, when a physiological alarm is notified, the state of the patient or the like is checked. When a sensor attached to the patient or the like is detached and a device alarm is notified, the sensor is attached to the patient or the like again.
However, as the number of sensors or medical devices attached to the patient or the like increases, the number of types and the number of times of the alarms to be notified increase, and the alarms may fatigue the medical staff or the like and may be ignored without being handled.
On the other hand, the notified alarms include a considerable number of alarms that do not need to be handled by the medical staff. For example, some alarms are caused by a noise due to a motion of the patient or the like being superimposed on a detection signal of a sensor. These alarms are naturally eliminated while the medical staff or the like is to take measures.
As a known technique for reducing such an alarm that does not need to be handled, there has been an alarm delay process of masking an alarm for a predetermined time from the occurrence of the alarm.
US2016/0093205A1 discloses the following prior art. Receive data related to a plurality of alarms generated in response to physiological parameters of each patient satisfying an alarm condition. Generate a plurality of validity indicators indicating the validity for a plurality of valid alarms based on information on the alarms input by the user. Analyze the data related to the plurality of alarms and the plurality of validity indicators. Then, correct at least one alarm condition based on the analysis.
However, in the alarm delay process described above, if relatively short-time alarms occur frequently, it may be actually necessary for the medical staff or the like to confirm the patient or the like or adjust the sensor, but no alarms are notified.
Similarly, if relatively short-time alarms occur frequently, the prior art disclosed in US2016/0093205A1 cannot appropriately issue alarm notification while reducing the number of alarms that do not need to be handled. Further, the prior art disclosed in US2016/0093205A1 is also complicated because it is necessary for the user to input information on the valid alarms to correct the alarm condition.
The presently disclosed subject matter has been made to solve the above problems. That is, an object of the presently disclosed subject matter is to provide an alarm control system, an alarm control method, and an alarm control program capable of appropriately notifying alarms while reducing alarms that do not need to be handled.
The above problems of the presently disclosed subject matter are solved by the following means.
(1) An alarm control system including:
(2) An alarm control method executed by an alarm control system, the alarm control method including:|
(3) A non-transitory computer-readable storage medium storing an alarm control program for causing a computer to execute:
The first alarm signal and the second alarm signal are output after generating the second alarm signal based on at least one of the first alarm signal generated based on the message signal related to the measurement of the physiological information or the period in which the measurement value of the physiological information is invalid calculated based on the output value of the physiological information. Accordingly, alarms can be appropriately notified while reducing the number of alarms that do not need to be handled.
Hereinafter, an alarm control system, an alarm control method, and an alarm control program according to an embodiment of the presently disclosed subject matter will be described in detail with reference to the drawings. In the drawings, the same elements are denoted by the same reference numerals, and the redundant description thereof is omitted.
The medical system 10 may include a centralized receiver communicably connected to the central monitor 100 and a plurality of transmitters wirelessly communicable with the centralized receiver. Some or all of the plurality of bed-side monitors 110 may be replaced by the centralized receiver and the plurality of transmitters.
The central monitor 100 and the bed-side monitors 110 are mutually and communicably connected via a wired or wireless network. Examples of the network include local area network (LAN) and wide area network (WAN). For example, Ethernet (registered trademark), Wi-Fi (registered trademark), Bluetooth (registered trademark), or 5G may be used as a communication standard of the network.
The controller 111 may include, for example, a central processing unit (CPU) and a random access memory (RAM), controls the components of the corresponding bed-side monitor 110, and performs various calculations.
The controller 111 causes the communication unit 113 to transmit the physiological information detected by the sensor 114 to the central monitor 100 as a detection signal of the physiological information. The controller 111 detects an abnormality in the physiological information based on the physiological information, and if an abnormality is detected, transmits a signal of a physiological alarm (vital alarm) for notifying the abnormality in the physiological information together with the physiological information to the central monitor 100 via the communication unit 113. The physiological information may include, for example, an electrocardiogram (ECG), the heart rate (HR), the arterial blood oxygen saturation (SpO2), the blood pressure, the respiration (RESP), and carbon dioxide (CO2) of expiration and inhalation. The abnormality of the physiological information can be detected by, for example, exceeding an upper limit value, a lower limit value, or upper and lower limit values set for the physiological information.
The controller 111 transmits a device alarm (technical alarm) generated and output by the electrode confirmation prevention processor 117 to the central monitor 100 through the communication unit 113. As described later, the device alarm signal may include an electrode confirmation alarm signal (see
The controller 111 may associate identification information for identifying the subject (patient or the like) of the physiological information with identification information for identifying the type of the alarm, and transmit the physiological information and the alarms to the central monitor 100 together with the identification information. The identification information for identifying the subject of the physiological information may include, for example, the bed number of the patient, the ID of the patient, and the IP address of the bed-side monitor 110. The identification information for identifying the type of alarm may include, for example, information indicating a device alarm of “electrode confirmation”, information indicating a physiological alarm of “heart rate”, and information indicating a physiological alarm of “irregular pulse”.
The memory 112 may include, for example, an SSD (solid state drive), and stores various data and various programs.
The communication unit 113 is an interface for communicably connecting the bed-side monitor 110 and the central monitor 100. The communication unit 113 may include, for example, an input terminal, an antenna, and a front-end circuit. The communication unit 113 may include an alarm output unit 113a. The alarm output unit 113a transmits (outputs) the alarms together with the identification information to the central monitor 100. Specifically, the alarm output unit 113a transmits, for example, an electrode confirmation alarm signal to the central monitor 100 in association with identification information indicating a device alarm of “electrode confirmation”.
The sensor 114 is a device or an element for detecting the physiological information. The sensor 114 may include, for example, ECG measurement electrodes, an SpO2 probe, a blood pressure sensor, a choroid sensor, a temperature sensor, a CO2 sensor, a gas sensor, a respiration sensor, a contact sensor, and other measurement sensors capable of detecting the physiological information. The sensor 114 may output the detection result of the physiological information as a detection signal of the physiological information.
The output unit 115 displays (outputs) the physiological information and the alarms in a visually recognizable manner. The output unit 115 may be configured with, for example, a liquid crystal display. The output unit 115 may include an amplifier and a speaker to output the alarms in an audibly recognizable manner. The output unit 115 may transmit (output) the physiological information and the alarms as data to another apparatus. The output unit 115 may be configured with a printer to output the physiological information and the alarms by forming an image on a sheet.
The ECG analysis processor 116 receives a detection signal of the physiological information detected by the sensor 114 and analyzes the received detection signal to calculate a message signal related to the measurement of the physiological information and an output value of the physiological information. The detection signal of the physiological information may include, for example, an electrocardiogram (detection signal of an electrocardiogram). The message signal related to the measurement of the physiological information is a message signal that is a digital signal indicating whether a device alarm has occurred. Specifically, a message signal related to the measurement of the physiological information may include, for example, an electrode confirmation message signal indicating whether “electrode confirmation” has occurred. The electrode confirmation message signal is an example of a sensor confirmation message signal related to the attachment of the sensor 114 to the subject. The sensor confirmation message signal may include an electrode confirmation message signal, a probe confirmation message, or the like. The output value of the physiological information is either a measurement value of the physiological information calculated from the detection signal detected by the sensor 114 or an invalid value of the physiological information (for example, a value indicating that the measurement (calculation) of the physiological information is impossible). Specifically, the output value of the physiological information may include, for example, an output value of the heart rate (hereinafter, referred to as an “HR output value”). The HR output value is either the measurement value of the heart rate or an invalid value of the heart rate. If the heart rate cannot be calculated from the electrocardiogram, the HR output value becomes an invalid value.
Hereinafter, in order to simplify the description, a case in which the detection signal of the physiological information is an electrocardiogram will be described as an example. In the described example, the message signal related to the measurement of the physiological information is an electrode confirmation message signal determined from the sensor signal of the electrocardiogram. In addition, in the described example, the output value of the physiological information is an HR output value calculated by analyzing an electrocardiogram.
The electrode confirmation in the electrode confirmation message signal is generated when the waveform is clipped in the electrocardiogram. The clipping may occur when the waveform of the electrocardiogram exceeds the input dynamic range of the electronic circuit of the ECG analysis processor 116. The measurement value of the heart rate in the HR output value is calculated by calculating the heart rate from the electrocardiogram. The method of calculating a heart rate from an electrocardiogram is publicly known, and thus the description thereof is omitted. The HR output value is set to an invalid value if the heart rate cannot be calculated due to the disturbance of the waveform of the electrocardiogram because, for example, a noise is superimposed on the waveform of the electrocardiogram, or if the heart rate cannot be calculated because no input signals of the electrocardiogram are output.
The processes in the ECG analysis processor 116 may be executed by a CPU (not illustrated) included in the ECG analysis processor 116. Some or all of the processes performed by the ECG analysis processor 116 may be executed by the controller 111.
The electrode confirmation prevention processor 117 generates and outputs an electrode confirmation alarm signal based on at least one of the electrode confirmation message signal or the HR output value. Hereinafter, the process of the electrode confirmation prevention processor 117 generating the electrode confirmation alarm signal based on at least one of the electrode confirmation message signal or the HR output value is referred to as “electrode confirmation prevention process”. Specifically, the electrode confirmation prevention processor 117 generates the first alarm signal by performing alarm delay process on the electrode confirmation message signal. The electrode confirmation prevention processor 117 calculates the frequency of electrode confirmation based on the electrode confirmation message signal. The electrode confirmation prevention processor 117 calculates a period in which the measurement value of the heart rate is an invalid value (a period in which the measurement value of the physiological information is invalid, hereinafter referred to as the “period in which the measurement value is invalid”) based on the HR output value. The period other than the period in which the measurement value is invalid is referred to as a period in which the measurement value is valid. The electrode confirmation prevention processor 117 generates the second alarm signal based on at least one of the frequency of electrode confirmation or the period in which the measurement value is invalid. Then, the electrode confirmation prevention processor 117 outputs the first alarm signal and the second alarm signal. The electrode confirmation prevention processor 117 may output an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal as the electrode confirmation alarm signal. That is, the electrode confirmation prevention processor 117 may output the logical sum (OR) of the first alarm signal and the second alarm signal as the electrode confirmation alarm signal. The electrode confirmation prevention processor 117 may output the first alarm signal and the second alarm signal as electrode confirmation alarm signals in a distinguishable manner, for example, by associating the electrode confirmation alarm signals with the identification information. Hereinafter, in order to simplify the description, a case where the electrode confirmation alarm signal is an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal will be described as an example.
Referring to
The alarm delay time may be determined by the following method based on the electrode confirmation alarm occurrence status and the response status thereof in the actually used environment or in a similar environment. For example, the alarm delay time may be determined such that the interruption of ECG monitoring due to electrode confirmation is the shortest as a result of: (1) data analysis; (2) machine learning including AI; (3) automatic learning; and (4) trial by an experimental method (trial and error, questionnaire, and the like).
The alarm delay time may be, for example, 5 seconds. Basically, relatively short-time electrode confirmation is highly probably device alarms that do not need to be handled. Therefore, the alarm delay process can prevent device alarms that do not need to be handled from being included in the electrode confirmation alarm signal.
Referring to
The first threshold may be determined by the following method based on the electrode confirmation alarm occurrence status and the response status thereof in the actually used environment or in a similar environment. For example, the first threshold may be determined such that the interruption of ECG monitoring due to electrode confirmation is the shortest as a result of: (1) data analysis; (2) machine learning including AI; (3) automatic learning; and (4) trial by an experimental method (trial and error, questionnaire, and the like).
The frequency of electrode confirmation may be the cumulative number of continuous electrode confirmation if electrode confirmation continues occurring within 30 seconds or less after the end of the previously occurring electrode confirmation. In this case, the first threshold may be three times. The first threshold may be, for example, three times per 30 seconds. As described above, since the electrode confirmation alarm signal is an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal, the result of the alarm delay process is reflected in the electrode confirmation alarm signal of
In the HR output value of
The second threshold may be determined by the following method based on the electrode confirmation alarm occurrence status and the response status thereof in the actually used environment or in a similar environment. For example, the second threshold may be determined such that the interruption of ECG monitoring due to electrode confirmation is the shortest as a result of: (1) data analysis; (2) machine learning including AI; (3) automatic learning; and (4) trial by an experimental method (trial and error, questionnaire, and the like).
The second threshold may be, for example, 30 seconds. As described above, since the electrode confirmation alarm signal is an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal, the result of the alarm delay process is reflected in the electrode confirmation alarm signal of
Referring to
The third threshold may be determined by the following method based on the electrode confirmation alarm occurrence status and the response status thereof in the actually used environment or in a similar environment. For example, the third threshold may be determined such that the interruption of ECG monitoring due to electrode confirmation is an appropriate time as a result of: (1) data analysis; (2) machine learning including AI; (3) automatic learning; and (4) trial by an experimental method (trial and error, questionnaire, and the like). The third threshold may be, for example, 5 seconds. As described above, since the electrode confirmation alarm signal is an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal, the result of the alarm delay process is reflected in the electrode confirmation alarm signal of
The electrode confirmation prevention process in the electrode confirmation prevention processor 117 may be executed by a CPU (not illustrated) included in the electrode confirmation prevention processor 117. A part or all of the electrode confirmation prevention process performed by the electrode confirmation prevention processor 117 may be performed by the controller 111. The electrode confirmation prevention processor 117 constitutes an obtaining unit, a first alarm signal generator, a calculation unit, a second alarm signal generator, and an output controller.
In the example of
In a comparative example in which the electrode confirmation prevention process is not performed, the electrode confirmation occurs in the electrode confirmation alarm signal at each timing when the waveform is clipped to the upper limit value in the electrocardiogram. Therefore, electrode confirmation is generated in response to frequent clipping, and the generated electrode confirmation highly probably include electrode confirmation that does not need to be handled.
In the embodiment in which the electrode confirmation prevention process is performed, the alarm delay process is performed, and the electrode confirmation is started in the electrode confirmation alarm signal when the frequency of the electrode confirmation in the electrode confirmation message signal becomes the first threshold or more or when the period in which the measurement value is invalid calculated based on the HR output value becomes the second threshold or more. Further, the electrode confirmation is ended in the electrode confirmation alarm signal when the period in which the measurement value is valid calculated based on the HR output value becomes the third threshold or more. Accordingly, the electrode confirmation can be appropriately notified while reducing electrode confirmation that does not need to be handled.
The controller 101 receives physiological alarm signals such as an electrocardiogram and an irregular pulse and electrode confirmation alarm signals, which are device alarm signals, from each bed-side monitor 110 by the communication unit 103.
The memory 102 stores the electrocardiogram, the physiological alarm signal, and the electrode confirmation alarm signal in association with the time. The electrocardiogram, the physiological alarm signal, and the electrode confirmation alarm signal may be stored in association with the identification information.
The output unit 104 displays (outputs) the electrocardiogram, the occurrence of the physiological alarm in the physiological alarm signal, and the occurrence of the electrode confirmation in the electrode confirmation alarm signal. The output unit 104 may include an amplifier and a speaker to output the alarms in an audibly recognizable manner. The output unit 104 may transmit (output) to another apparatus as data the electrocardiogram, the generation of the physiological alarm in the physiological alarm signal, and the occurrence of the electrode confirmation in the electrode confirmation alarm signal. The output unit 104 may be configured with a printer to output the electrocardiogram, the occurrence of the physiological alarm in the physiological alarm signal, and the occurrence of the electrode confirmation in the electrode confirmation alarm signal by forming an image on a sheet.
The alarm generator 105 notifies the generation of the physiological alarm included in the physiological alarm signal by outputting voice, light, image, or the like. The alarm generator 105 notifies the generation of the electrode confirmation included in the electrode confirmation alarm signal by outputting sound, light, image, vibration, indicator, or the like. The alarm generator 105 may output the alarms for each type of alarm in a manner recognizable by the difference in, for example, tone, color of light, images, or the like.
In the example of
In the present embodiment, the generation of the electrode confirmation alarm signal and the generation of the physiological alarm signal may be performed independently. However, the electrode confirmation alarm signal and the physiological alarm signal may be generated using the same input signal. Accordingly, the physiological alarm in the physiological alarm signal can be generated even during the period in which the electrode confirmation is generated in the electrode confirmation alarm signal. That is, for example, irregular pulse can be detected based on the electrocardiogram simultaneously when electrode confirmation is generated in the electrode confirmation alarm signal, and electrode confirmation in the electrode confirmation alarm signal and a physiological alarm of irregular pulse in the physiological alarm signal can be generated as follows when irregular pulse is detected. Examples include: (1) simultaneously generate electrode confirmation and a physiological alarm; (2) prioritizing a physiological alarm rather than electrode confirmation; and (3) prioritizing electrode confirmation rather than a physiological alarm.
The operation of the medical system 10 will be described.
The electrode confirmation prevention processor 117 obtains the electrode confirmation message signal and the HR output value from the ECG analysis processor 116 (S101).
The electrode confirmation prevention processor 117 performs the alarm delay process on the electrode confirmation message signal to generate a first alarm signal (S102). The first alarm signal is merged with the second alarm signal generated in the step described below in each period of time, and then transmitted (output) to the central monitor 100 as the electrode confirmation alarm signal.
The electrode confirmation prevention processor 117 calculates the frequency of electrode confirmation based on the electrode confirmation message signal (S103).
The electrode confirmation prevention processor 117 calculates the period in which the measurement value is invalid based on the HR output value (S104).
The electrode confirmation prevention processor 117 determines whether the frequency of electrode confirmation is the first threshold or more (S105). If it is determined that the frequency of electrode confirmation is the first threshold or more (S105: YES), the electrode confirmation prevention processor 117 starts electrode confirmation in the generated second alarm signal (S107).
If it is determined that the frequency of electrode confirmation is not the first threshold or more (S105: NO), the electrode confirmation prevention processor 117 determines whether the period in which the measurement value is invalid is the second threshold or more (S106). If it is determined that the period in which the measurement value is invalid is not the second threshold or more (S106: NO), the electrode confirmation prevention processor 117 returns to step S103 and continues the processing.
If the electrode confirmation prevention processor 117 determines that the period in which the measurement value is invalid is the second threshold or more (S106: YES), the electrode confirmation prevention processor 117 starts electrode confirmation in the second alarm signal (S107).
The electrode confirmation prevention processor 117 calculates the period in which the measurement value is valid based on the HR output value (S108).
The electrode confirmation prevention processor 117 determines whether the period in which the measurement value is valid is the third threshold or more (S109). If the electrode confirmation prevention processor 117 determines that the period in which the measurement value is valid is not the third threshold or more (S109: NO), the electrode confirmation prevention processor 117 returns to step S108 and continues the processing.
If the electrode confirmation prevention processor 117 determines that the period in which the measurement value is valid is the third threshold or more (S109: YES), the electrode confirmation prevention processor 117 ends the electrode confirmation in the second alarm signal (S110).
The embodiment described above has described an example in which the detection signal of the physiological information detected by the sensor 114 is an electrocardiogram.
However, the detection signal of the physiological information detected by the sensor 114 may be the arterial blood oxygen saturation, the blood pressure, the respiration, carbon dioxide (CO2) of expiration and inhalation, the ST value, the VPC rate, the pulse rate, the CCO value, a score (indicating the condition of the patient), and the like.
The ECG analysis processor 116 analyzes the detection signal of the physiological information to calculate the message signal related to the measurement of the physiological information and the output value of the physiological information. The ECG analysis processor 116 may calculate a plurality of message signals related to the measurement of physiological information. The ECG analysis processor 116 may calculate a plurality of output values of the physiological information. The message signal related to the measurement of the physiological information may include a signal of any message related to the measurement of the physiological information. The message signal related to the measurement of the physiological information may be a message signal indicating whether “radio wave interruption” has occurred or a message signal indicating whether “probe confirmation” has occurred. Alternatively, the message signal related to the measurement of the physiological information may be a message signal indicating whether electromagnetic interference has occurred, whether occlusion of a line or a flow has occurred, or whether device failure has occurred. The output value of the physiological information may be an output value of the QT time, an output value of the R-R time, an output value of the P-P time, an output value of the blood pressure, or the like.
The electrode confirmation prevention processor 117 generates and outputs a measurement-related alarm signal based on at least one of the message signal related to the measurement of the physiological information or the output value of the physiological information. The electrode confirmation prevention processor 117 may generate and output the measurement-related alarm signal based on a plurality of message signals related to the measurement of the physiological information and a plurality of output values of the physiological information. The measurement-related alarm signal may include all the alarm signals related to the measurement of the physiological information. The measurement-related alarm signal is not limited to the electrode confirmation alarm signal, and may be a signal for notifying an alarm of “radio wave interruption” or a signal for notifying an alarm of “probe confirmation”. Alternatively, the measurement-related alarm signal may be a signal for notifying an alarm of electromagnetic interference, a signal for notifying an alarm of occlusion of a line or a flow, or a signal for notifying an alarm of device failure.
The bed-side monitor 110 may further include a switching unit for switching between a first mode and a second mode. The first mode is for outputting a message signal related to the measurement of the physiological information in place of the electrode confirmation alarm signal. The second mode is for outputting an electrode confirmation alarm signal (that is, an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal). The switching unit may be configured with the controller 111. For example, the controller 111 may receive a switching control signal based on a switching input by the user to a user terminal (not illustrated) from the user terminal by the communication unit 113, and switch between the first mode and the second mode based on the switching control signal.
In the present modification, the ECG analysis processor 116 and the electrode confirmation prevention processor 117 is not included in the transmitter 210 by included in the central monitor 100. Accordingly, a detection signal of physiological information is transmitted from each transmitter 210 to the central monitor 100 by the communication unit 113 through wireless communication. The ECG analysis processor 116 included in the central monitor 100 analyzes the received detection signal to calculate the message signal related to the measurement of the physiological information and the output value of the physiological information. The electrode confirmation prevention processor 117 included in the central monitor 100 generates and outputs a device alarm signal based on at least one of the message signal related to the measurement of the physiological information or the output value of the physiological information. The device alarm signal may include an electrode confirmation alarm signal (see
The embodiment has the following effects.
The first alarm signal and the second alarm signal are output after generating the second alarm signal based on at least one of the first alarm signal generated based on the message signal related to the measurement of the physiological information or the period in which the measurement value of the physiological information is invalid calculated based on the output value of the physiological information. Accordingly, alarms can be appropriately notified while reducing the number of alarms that do not need to be handled.
The second alarm signal generator starts an alarm in the second alarm signal if at least one of a first condition or a second condition is satisfied, and does not start the alarm in the second alarm signal if neither the first condition nor the second condition is satisfied, the first condition being an occurrence frequency of the message signal related to the measurement being a predetermined first threshold or more, and the second condition being the period in which the measurement value is invalid being a predetermined second threshold or more. Accordingly, it is possible to easily and appropriately notify alarms that highly probably need to be handled while reducing the alarms that do not need to be handled.
When an alarm is started in the second alarm signal, the alarm in the second alarm signal is continued until a period in which the measurement value is valid continues for a predetermined third threshold or more. Accordingly, it is possible to call attention to an alarm if the alarm continues for a relatively long time and thus needs to be handled, while appropriately reducing the occurrence of alarms.
After the alarm is started in the second alarm signal, the alarm in the second alarm signal is ended if the period in which the measurement value is valid continues for the third threshold or more. Accordingly, it is possible to call attention to an alarm by the alarm continuing for an appropriate time, while appropriately reducing the occurrence of alarms.
The message signal related to the measurement is a message signal of sensor confirmation related to attachment of a sensor for measuring the physiological information to a measurement subject. As a result, it is possible to simply and more appropriately notify a message of sensor confirmation that highly probably needs to be handled, while reducing messages of sensor confirmation that do not need to be handled.
With respect to the message signal of the sensor confirmation, the first alarm signal is generated by masking the sensor confirmation for a predetermined time from occurrence of the sensor confirmation. Accordingly, it is possible to appropriately reduce electrode confirmation that does not need to be performed.
Control is performed to output the first alarm signal and the second alarm signal as an integrated alarm signal obtained by merging the first alarm signal and the second alarm signal. Accordingly, it is possible to perform appropriate alarm notification such that the number of types of alarms to be notified is reduced while reducing the number of alarms that do not need to be handled.
A switching unit, which is configured to switch between a first mode for outputting a message signal related to the measurement and a second mode for outputting the integrated alarm signal, performs control to output the message signal related to the measurement when the switching unit switches to the first mode, and performs control to output the integrated alarm signal when the switching unit switches to the second mode. Accordingly, it is possible to perform appropriate alarm notification flexibly according to the intention of the user, while reducing the alarms that do not need to be handled.
The physiological information is a heart rate, an electrocardiogram, an SpO2, a respiratory rate, an ST value, a VPC rate, a pulse rate, a CCO value, or a score indicating a condition of a measurement subject. Accordingly, in the measurement of the physiological information, it is possible to expand the range of the physiological information in which the alarm notification can be performed appropriately, while reducing the alarms that do not need to be handled.
The first alarm signal and the second alarm signal are alarm signals of electrode confirmation. Accordingly, it is possible to more easily and appropriately notify electrode confirmation that highly probably needs to be handled, while reducing electrode confirmation that does not need to be handled.
The message signal related to the measurement is a message signal of electrode confirmation, and the output value of the physiological information is an output value of a heart rate. Accordingly, it is possible to more easily and appropriately notify electrode confirmation that highly probably needs to be handled, while reducing electrode confirmation that does not need to be handled.
