The disclosure relates to a technical field for a medical device, and more particularly to a patient monitoring device and an alarm method for patient monitoring.
Patient monitoring device has a function of detecting various physiological parameter signals of a patient, and can also send an alarm when the physiological parameter signals are abnormal, so that medical staff can manage the patient more conveniently. Conventional patient monitoring device only has a single alarm function based on a single physiological parameter. For example, when the patient monitoring device is provided with an alarm for exceeding a threshold of an SpO2 (blood oxygen saturation) parameter, and its alarm level is preset to be medium level. When the patient monitoring device detects that an SpO2 parameter value is lower than a lower threshold of the SpO2 parameter, an alarm character string of “SpO2 too-low” automatically pops up in an alarm area of the device with a yellow background. At the same time, a medium-level alarm sound and light are used to remind medical staff to pay attention to this single alarm generated based on the signal of blood oxygen saturation parameter. Similarly, when the patient monitoring device is a multi-parameter monitoring device, the patient monitoring device is usually also provided with single alarms based on other physiological parameters, such as an alarm for exceeding a threshold of an RR parameter based on a respiratory parameter, and its alarm level is preset to be medium level. When an RR parameter value detected is lower than a lower threshold of the RR parameter, an alarm character string of “RR too-low” will automatically pop up in the alarm area of the device with a yellow background. At the same time, the medium-level alarm sound and light are used to remind medical staff to pay attention to this single alarm generated based on the respiratory parameter signal. If the patient monitoring device detects that an SpO2 parameter value is lower than the lower threshold of the SpO2 parameter and an RR parameter value is lower than the lower threshold of the RR parameter at the same time, alarm characters “SpO2 too-low” and “RR too-low” are displayed alternately in the same alarm area with a yellow background, and a medium-level alarm sound and light are used to remind. This alarm mode causes medical staff to focus mainly on single alarm information, and they are prone to ignore or simply fail to notice two or more related alarms occurring simultaneously among so many alarm characters displayed alternately. These related and simultaneous alarms often represent a more serious physiological condition of the patient, or represent that the physiological condition of the patient is or is about to deteriorate. Although particularly experienced medical staff can determine from experience that the simultaneous occurrence of different single alarms may increase a pathological risk of the patient, overall, ignoring or failing to notice the existence of two or more alarms that indicate a more serious, or currently deteriorating or soon-to-be-deteriorating, physiological condition of the patient still affects timeliness of intervention of medical staff to the patient.

As shown in
The signal acquiring apparatus 10 is configured to acquire a physiological parameter signal, for example, to acquire a physiological parameter signal which corresponds to at least one physiological parameter of a patient, wherein the physiological parameter may also be referred to as a vital sign parameter. When the acquired physiological parameter signal includes more than two physiological parameters, in order to distinguish the two or more physiological parameters, a first physiological parameter and a second physiological parameter can be used, respectively. Correspondingly, a first physiological parameter signal and a second physiological parameter signal can be used to represent the physiological parameter signals corresponding to the two different physiological parameters, respectively.
The patient monitoring device may be any one of a monitor, a local central station, a remote central station, a cloud service system, and a mobile terminal, and the corresponding signal acquiring apparatus 10 acquires the physiological parameter signal in different ways. For example, if the patient monitoring device is a monitor, the signal acquiring apparatus 10 may use a sensor to monitor a physiological parameter of the patient and obtain a physiological parameter signal which corresponds to the physiological parameter. The physiological parameter may include various vital sign parameters, such as electrocardiogram, respiration, non-invasive blood pressure, blood oxygen saturation, pulse, body temperature, invasive blood pressure, end-respiratory carbon dioxide, respiratory mechanics, anesthetic gas, cardiac output, bi-spectral index, etc. The physiological parameter signal may be an original acquired electrical signal, and the corresponding physiological parameter signal may be visualized on the display 30 by at least one of numerical value(s), waveform(s), and a trend of change for waveform(s). For another example, the patient monitoring device may be a local central station, a remote central station, a cloud service system, or a mobile terminal, then the signal acquiring apparatus 10 is a communication device or a communication interface for communicating with a monitor to acquire the above-mentioned physiological parameter signal from the monitor. Alternatively, the patient monitoring device can also be a local central station, a remote central station, a cloud service system or a mobile terminal, then the signal acquiring apparatus 10 is a communication device or a communication interface, which is configured to communicate with a monitor, so as to obtain from the monitor, an original signal which is acquired by a sensor of the monitor; perform calculation(s) on the original signal, so as to obtain a physiological parameter signal which corresponds to the physiological parameter; and transfer the obtained physiological parameter signal to the monitor.
The processor 20 can be configured to process a physiological parameter signal of at least one physiological parameter, and generate a first alarm when determining that the physiological parameter signal of the at least one physiological parameter satisfies a first alarm rule. The processor 20 can analyse the physiological parameter signal to determine whether it satisfies a preset first alarm rule. The first alarm rule can be stored in a memory that cooperates with the processor 20 and can be read or called by the processor 20.
Taking a blood oxygen saturation parameter as an example, the processor 20 calculates a current value of blood oxygen saturation according to an analysis on a blood oxygen saturation signal. The corresponding first alarm rule may be, for example, an alarm rule for extremely-low blood oxygen saturation. The alarm rule for extremely-low blood oxygen saturation may be specifically explained as that a blood oxygen saturation value is less than an extremely-low threshold of blood oxygen saturation (e.g., 80%). When the monitored blood oxygen saturation value is less than the extremely-low threshold of blood oxygen saturation, the processor 20 determines that the blood oxygen saturation signal satisfies the alarm rule for extremely-low blood oxygen saturation, and generates a first alarm, namely, an alarm for extremely-low blood oxygen saturation. Similarly, the first alarm rule may also be, for example, an alarm rule for too-low blood oxygen saturation, and the alarm rule for too-low blood oxygen saturation may be specifically explained as that a blood oxygen saturation value is less than a too-low threshold of blood oxygen saturation (e.g., 90%). When the monitored blood oxygen saturation value is less than the too-low threshold of blood oxygen saturation, the processor 20 determines that the blood oxygen saturation signal satisfies the alarm rule for too-low blood oxygen saturation, and generates a first alarm, namely, an alarm for too-low blood oxygen saturation.
Further taking the blood oxygen saturation parameter as an example, the processor 20 further calculates a current value of blood oxygen saturation according to an analysis on a blood oxygen saturation signal. The corresponding first alarm rule may be, for example, an alarm rule for extremely-low blood oxygen saturation. The alarm rule for extremely-low blood oxygen saturation may be specifically explained as that a blood oxygen saturation value is less than an extremely-low threshold of blood oxygen saturation (e.g., 80%). When the monitored blood oxygen saturation value is less than the extremely-low threshold of blood oxygen saturation, the processor 20 determines that the blood oxygen saturation signal satisfies the alarm rule for extremely-low blood oxygen saturation and generates a first alarm, namely, an alarm for extremely-low blood oxygen saturation. The first alarm can also be an alarm for too-low arterial pressure, an alarm for respiratory suffocation, an alarm for extreme tachycardia, an alarm for extreme bradycardia, etc. The corresponding first alarm rules can be an alarm rule for too-low arterial pressure, an alarm rule for respiratory suffocation, an alarm rule for extreme tachycardia, an alarm rule for extreme bradycardia, etc. For more examples, please refer to the multiple first alarms listed in the first column of Tables 1-3. The first alarm rules corresponding to the first alarms in the examples in the tables are not described one by one here.
When the processor 20 generates the first alarm, the display 30 presents first alarm information in a predetermined first alarm area, wherein the first alarm information represents the first alarm. The first alarm information may be an alarm character string. Taking the alarm for extremely-low blood oxygen saturation (alarm for extremely-low SpO2) as an example, when an alarm for extremely-low SpO2 is generated, the display 30 displays a character string such as “Extremely-low SpO2” in a predetermined first alarm area. In this disclosure, “representing first alarm” does not limit a specific physical location and area occupied by the first alarm area on the display. The first alarm information is presented in a first presentation mode. In a specific example, the first presentation mode includes displaying the first alarm information in the first alarm area with a first background color. For example, if the first alarm is a medium-level alarm, the first alarm information can be displayed in the first alarm area with a medium-level alarm color (such as yellow). Specifically, taking the alarm for extremely-low SpO2 as an example, the alarm character string of “Extremely-low SpO2” may be displayed in the first alarm area with a background color corresponding to a high-level alarm (e.g., red). When only the first alarm exists, the display 30 may present the first alarm in a presentation mode corresponding to a severity level to which the alarm belongs.
The processor 20 is further configured to control the display 30 to display the first alarm information in a second presentation mode, when determining that the physiological parameter signal of at least one physiological parameter simultaneously satisfies the first alarm rule and the second alarm rule, wherein the second alarm rule is different from the first alarm rule, and the second presentation mode is an upgrade based on the first presentation mode. Specifically, when the monitored physiological parameter signal continues to be in a state of satisfying the first alarm rule, the first alarm information continues to be presented in the first presentation mode. At this time, if the monitored physiological parameter signal also satisfies the second alarm rule, according to general practice, an independent second alarm is to be generated and presented separately based on the physiological parameter signal which satisfies the second alarm rule. This disclosure upgrades the presentation mode of the first alarm information to more intuitively remind medical staff that the first alarm indicates that the physiological state of the patient has become more serious due to an existence of the second alarm, thereby more intuitively and timely reminding medical staff that the pathological risk of the patient may increase, so that timely intervention can be made on the patient.
The first alarm rule or the second alarm rule may include an alarm rule for exceeding a threshold, that is, the physiological parameter exceeds an alarm threshold. Alternatively, the first alarm rule or the second alarm rule may also include an alarm rule for an event, that is, an alarm rule for an abnormal event, wherein the alarm rule for an abnormal event is configured to determine whether the patient is in an abnormal state, such as whether the patient is in any one or more of respiratory suffocation, possible shock, atrial fibrillation, arrhythmia, etc.
It is worth mentioning that in this disclosure, the second presentation mode is an upgrade based on the first presentation mode, that is, it refers to a display mode that is more noticeable to user than an alarm display mode of the first presentation mode, including but not limited to, occupying a larger area to display the alarm, displaying the alarm by continuously flashing the alarm on the screen, displaying the alarm with brighter or thicker background color, etc.
The second presentation mode may be any display mode that is more noticeable to the user than the first presentation mode. In one embodiment, the first presentation mode includes displaying the first alarm information in the first alarm area with a first background color, and the second presentation mode includes displaying the first alarm information in the first alarm area with a second background color, wherein the second background color has a stronger warning effect than the first background color. For example, please refer to
However, it is not limited to this. For example, as shown in
In another example, the first alarm information may also be displayed in the first alarm area 201 with a flashed first background color or a flashed second background color. Since being flashed itself has a stronger warning effect than not being flashed, the presentation mode of the first alarm information can be upgraded only by adding the flashing or increasing a flashing frequency. Therefore, the background color can be maintained as the first background color. Of course, the presentation mode of the first alarm information can also be upgraded by flashing a second background color to achieve a stronger warning effect. In other examples, the first alarm information may also be displayed in a second alarm area outside the first alarm area. For example, the first alarm information may be displayed in a pop-up window in a second alarm area outside the first alarm area on the main interface of the display. Alternatively, the second alarm area may also be a display area embedded in the main interface. The first alarm information of the first alarm area 201 may be displayed at the same time, or not displayed.
In another example, the second presentation mode may further include simultaneously displaying the second alarm information and the first alarm information in an associated combination mode, wherein the second alarm information represents that the physiological parameter signal of the at least one physiological parameter satisfies the second alarm rule. Upgrading the alarm presentation mode by adding the second alarm information on the basis of the first alarm information can also be regarded as presenting the first alarm and the second alarm in a combined alarm mode, so that it can be more intuitive to see that the second alarm accompanies with the first alarm.
Please refer to
While the first alarm information is being updated and presented, the accompanied second alarm may also be displayed separately, for example, the second alarm information may be displayed separately in the second alarm area 202.
The first alarm area 201 and the second alarm area 202 may be arranged side by side from up to down as shown in
In order to more clearly show an accompanied relationship between the first alarm and the second alarm, the first alarm information and the second alarm information may be associated with each other through an associated character string to form combined alarm information, wherein the associated character string represents that the second alarm information accompanies with the first alarm information. The associated character string can be one of word(s), symbol(s), and mark(s), or any combination thereof. Optionally, symbol(s) include(s) but is(are) not limited to one or more of a comma, “&” symbol, bracket, or semicolon, word(s) include(s) but is(are) not limited to conjunction(s), such as “and”, “with”, “accompanies with”, etc. For example, in
It should be understood that the associated character string is not limited to the examples disclosed in this disclosure, and may be any other character string as long as it can reflect the accompanied relationship between the first alarm and the second alarm.
Adding the accompanied second alarm information to the first alarm information, is also an upgraded presentation of the first alarm information. By combining two or more alarm information, two related alarms can be presented in a related combination mode (that is, in the combined alarm mode), which can more intuitively remind medical staff of the increased pathological risk of patient caused by the simultaneous occurrence of two or more related alarms.
It is worth mentioning that, in this disclosure, “a combined alarm” can be understood as presenting the first alarm information and the second alarm information in combination through an associated character string, such as hyphen(s) (such as commas, semicolons, etc.), conjunction(s) (such as “and”, “with”, “accompanied by” . . . , etc.), so as to form “combined alarm” information. The combined alarm information can present more specific alarm information to medical staff in multiple dimensions, so that medical staff can understand the condition of the patient more clearly. The first alarm information and the second alarm information associated with each other through the associated character string may be displayed on the display 30 only when duration(s) of the alarm(s) exceed(s) preset time length(s). In this way, the presentation of some alarm information in the case where the alarm rule is briefly satisfied but soon not satisfied on its own, can be ignored, so that medical staff can only focus on the alarm information, which requires more attention and is of long duration.
When the physiological parameter signal of at least one physiological parameter no longer satisfies the second alarm rule, the display 30 clears the second alarm information. If a third alarm that satisfies another alarm rule occurs at the same time, and the third alarm is also associated with the first alarm, the first alarm and the third alarm can continue to be presented in a combined alarm mode.
Please refer to
In order to enable the user to pay attention to more dangerous alarm(s), the first alarm area and the second alarm area can be distinguished by different background colors. For example, the background color of the first alarm area has a stronger warning effect than the background color of the second alarm area, and the accompanied alarm and the separate second alarm can be distinguished and warned, so as to more clearly remind medical staff of existence of the accompanied second alarm without affecting the medical staff to quickly and promptly check the separate second alarm information due to other clinical needs.
Please refer to
The foregoing mainly uses a situation where the alarm for too-low SpO2 is accompanied by the alarm for high RR to explain some embodiments of upgrading the presentation of the alarm for too-low SpO2, wherein the alarm for too-low SpO2 is an alarm associated with the blood oxygen saturation parameter, and the blood oxygen saturation signal can be analysed to determine whether it satisfies the alarm rule for too-low SpO2, while the alarm for high RR is an alarm associated with the respiratory parameter, and the respiratory signal can be analysed to determine whether it satisfies the alarm rule for high RR. That is to say, the first alarm rule and the second alarm rule in the foregoing example are respectively associated with different physiological parameters, and the corresponding first alarm and second alarm are also associated with different physiological parameters. However, the first alarm in this disclosure is not limited to the alarm for too-low SpO2, nor to the alarm associated with the blood oxygen saturation parameter. The first alarm and the second alarm may also be associated with the same physiological parameter, or the first alarm is associated with a first physiological parameter, and the second alarm is associated with one or more physiological parameters which is(are) different from the first physiological parameter.
Please refer to Table 1, which shows some conditions and modes for upgrading and presenting first alarm information in a list form.
The 2nd to 7th rows of the 1st column in the table respectively illustrate four first alarms: an alarm for respiratory suffocation, an alarm for extreme tachycardia, an alarm for extreme bradycardia, and an alarm for extremely-low SpO2. The 2nd to 7th rows of the 2nd column correspond to upgrade conditions for upgrading the first alarms in the same row, and the upgrade conditions are that a duration of a first alarm exceeds a preset threshold, that is, the second alarm rule is that a duration, in which the first alarm rule is satisfied, exceeds the preset threshold, and the 3rd column corresponds to the upgraded alarm level. Taking the first alarm as an alarm for respiratory suffocation as an example, the alarm for respiratory suffocation is generated based on the respiratory parameter signal, and the corresponding alarm rule for respiratory suffocation is also associated with the respiratory parameter. When the processor analyses the respiratory parameter signal and determines that the respiratory parameter signal satisfies the alarm rule for respiratory suffocation, the alarm for respiratory suffocation is generated. When the alarm for respiratory suffocation occurs and continues for less than 20 s, the display 30 presents the first alarm information “respiratory suffocation” at a medium level or low level. When a duration of the alarm for respiratory suffocation exceeds a preset value of 20 s, it is equivalent to that the second alarm rule has been satisfied. The second alarm rule and the first alarm rule here are both associated with the same physiological parameter, that is, the respiratory parameter, wherein the second alarm rule can be expressed as a time length, in which the respiratory parameter signal continuously satisfies the first alarm rule, exceeds the preset value, so the column of the upgrade condition can essentially be regarded as a second alarm rule. When the upgrade condition or the second alarm rule is satisfied, the display 30 presents the first alarm at a relatively higher alarm level to indicate that the respiratory suffocation poses a higher risk to the patient due to prolonged duration, thereby attracting the attention of medical staff more promptly so that timely intervention can be provided to the patient.
The multiple first alarms recorded in the first column of Table 1 may be alarms associated with a blood oxygen saturation parameter, an electrocardiogram parameter, a respiratory parameter, or a blood pressure parameter, and the corresponding first alarm rules may be that a signal of blood oxygen saturation parameter exceeds an alarm threshold for the blood oxygen saturation parameter, an electrocardiogram parameter signal exceeds an alarm threshold for the electrocardiogram parameter, a respiratory parameter signal exceeds an alarm threshold of the respiratory parameter, and a parameter signal of a blood pressure exceeds the alarm threshold of the blood pressure parameter.
It should also be noted that an upgraded presentation level of the first alarm information only needs to be converted from a relatively low level to a relatively high level. For example, the upgraded level in the table is higher than the level before the upgrade. For example, if the upgraded level is a high level, then the level before the upgrade may be a medium level. For another example, if the upgraded level is exclusive, then the level before the upgrade may be medium level or high level. The “Exclusive level” shown in Table 1-3 is a more prominent alarm presentation mode than the “high level”. For example, the alarm area for an alarm presentation mode of the “exclusive” level is larger than that for an alarm presentation mode of the “high level”; or a font in an alarm presentation mode of the “exclusive” level is enlarged, or other alarm presentation modes that can make the alarm more prominent are used in the alarm presentation mode of the “exclusive” level.
“Additional character string for alarm” in 4th column of Table 1 is displayed as “None”, which means that after the first alarm satisfies the upgrade condition, no additional character string for alarm is added on the basis of the displayed first alarm information, and the original first alarm information is still displayed, for example, “alarm for extremely-low SpO2” is still displayed. Of course, in other examples, the duration of the first alarm can also be used as an additional alarm character.
Please refer to Table 2, which lists more examples of combined alarm upgrades, wherein the second alarm rule (i.e., upgrade condition) is associated with a second physiological parameter, and the first alarm rule is associated with a first physiological parameter. It may be that when the first physiological parameter satisfies the first alarm rule, and the second physiological parameter satisfies the second alarm rule, the alarm is presented in an upgraded mode, for example, in the combined alarm mode. Alternatively, the processor 20 is further configured to control the display 30 to simultaneously present the first alarm information and the second alarm information in an associated combination mode (wherein the associated combination mode can be understood as the combined alarm mode), when determining that the first physiological parameter satisfies the first alarm rule, and the second physiological parameter satisfies the second alarm rule. The second alarm rule includes: the second physiological parameter satisfies an alarm rule for exceeding a threshold and/or an alarm rule for an event; and duration(s) exceed(s) preset time length(s), in which duration(s) the second physiological parameter satisfies the alarm rule for exceeding a threshold and/or the alarm rule for an event. The first alarm information represents that the first physiological parameter satisfies the first alarm rule, and the second alarm information represents that the second physiological parameter satisfies the second alarm rule.
Similar to the situation that the alarm for too-low SpO2 accompanies with the alarm for high RR, described in the previous article, take the combination in which an alarm for too-low SpO2 accompanies with an alarm for high RR in the table as an example, such alarm combination is still a combined alarm, which is generated based on the signal of blood oxygen saturation parameter and the respiratory parameter signal. The difference is that only when: the monitored physiological parameter signal satisfies the first alarm rule (alarm rule for extremely-low SpO2, alarm rule for too-low SpO2, alarm rule for extremely-low SpO2b or alarm rule for too-low SpO2b), and satisfies the second alarm rule (such as alarm rule for too-high RR, or alarm rule for too-low RR); and a duration, in which the monitored physiological parameter signal satisfies the first alarm rule and the second alarm rule, exceeds a preset threshold, such as 120 s; the first alarm information (such as alarm for extremely-low SpO2, alarm for too-low SpO2, alarm for extremely-low SpO2b or alarm for too-low SpO2b) is presented in an upgraded mode. In other words, the accompanied alarm for too-high RR, which alarm continues less than 120 s may have little impact on the risk level of the patient and does not need to warn medical staff in a more noticeable way.
Please refer to Table 3, which lists more combination alarms, wherein the first physiological parameter is a blood pressure parameter, the first alarm rule includes an alarm rule for too-low arterial pressure, the second physiological parameter is an electrocardiogram parameter, and the second alarm rule includes at least one of: an alarm rule for too-low HR, an alarm rule for bradycardia, an alarm rule for tachycardia, an alarm rule for atrial fibrillation, an alarm rule for ventricular rhythm, an alarm rule for bigeminy ventricular premature contraction, an alarm rule for trigeminy premature ventricular contraction, an alarm rule for too-high ST, an alarm rule for too-low ST, an alarm rule for a single ΔST that exceeds a threshold, and an alarm rule for multiple ΔSTs that exceed threshold(s).
Continuing to refer to
In one example, the combined alarm mode includes displaying the first alarm information and the second alarm information in combination through an associated character string, wherein the associated character string represents that the second alarm accompanies with the first alarm.
In addition, in the relatively fixed first alarm area 410 of the main interface, each single alarm can be displayed separately. For example, HR>100, Art-Sys<90, RR>22 can be scrolled and displayed in the first alarm area 410. Of course, the simultaneous occurrence of these single alarms can also be displayed in the combined alarm mode in the first alarm area 410.
On the basis of separate outputs of the single alarms, the first alarm information and the second alarm information are simultaneously presented in the combined alarm mode, which makes it easier for medical staff to pay attention to the occurrence of the combined alarm.
In order to facilitate the doctor to observe the patient state, the patient state window 420 shown in
After acquiring the patient data (including at least a physiological parameter signal of at least one physiological parameter of the patient, and may also including treatment device data, drug administration data, laboratory test data, imaging data, and diagnostic data, etc.), the processor 20 analyses the patient data according to a preset rule, so as to obtain the patient state. For example, the processor 20 analyses the patient data based on a state determination rule database stored in the memory. The state determination rule database stores rules for determining the patient state. These rules can be preset by the user, or can be automatically generated through big data learning. The automatically generated rules can be processed manually to eventually form recognized rules in the rule base.
Then, on the display 130, the patient state is presented in the form of a human body diagram, and at least one item of alarm information, which is associated with the patient state, is presented in the form of text or graphic in the combined alarm mode. For example, a dedicated patient state window 420 may be configured to display the patient state, and display, in the combined alarm mode, the at least one item of alarm information which is associated with the patient state. Here, the “dedicated patient state window” can be understood as a window that is different and independent from common areas or windows that display patient data, alarm data, etc., on a medical device, such as a monitor. Specifically, the patient state window 131 includes a unit for a human body diagram 4201 and a unit for details of a patient state 4202, wherein the unit for a human body diagram 4201 displays the patient state, such as one or more of an overall state of the patient, a physiological system state, an organ state, a physiological part state, and a tissue state. The unit for details of a patient state 4202 displays, in the combined alarm mode, at least one item of alarm information which is associated with the patient state, such as an alarm which is generated, when at least one physiological parameter, which parameter is associated with the patient state, satisfies a preset alarm condition, and a duration of the alarm, etc. In an embodiment of this disclosure, the patient data is analysed, so as to obtain the patient state and the at least one item of alarm information which is associated with the patient state and presented in the combined alarm mode; and the patient state is graphically presented to the medical staff in the form of the human body diagram, while the at least one item of alarm information, which is associated with the patient state, is further presented to the medical staff via text or graph in the combined alarm mode, so that the medical staff can intuitively and clearly know the patient state and related alarm condition, thereby facilitating the medical staff to quickly take treatment measure according to the patient state.
In an embodiment of this disclosure, the unit for a human body diagram 4201 can present a human body diagram, and present the patient state by marking the human body diagram. On the human body diagram, when the patient state includes the overall state of the patient, the entirety human body diagram is marked. When the patient state includes one or more of the physiological system state, the organ state, the physiological part state, and the tissue state, one or more of physiological system, organ, physiological part, and tissue, which corresponds/correspond to the patient state, are marked. Therefore, the human body diagram may be a complete human body diagram (including a complete human body) or at least a partial human body diagram (including at least a partial human body). By presenting the human body diagram and marking the human body diagram to present the patient state, medical staff can very intuitively view the overall state of the patient or the state of certain physiological system, organ, physiological part, tissue, etc., of the patient.
In an embodiment of this disclosure, the human body diagram can be marked via at least one of graph information, symbol information, color information, and text information, which is located on or adjacent to the human body diagram, thereby presenting the patient state. The patient state may include whether one or more of the overall state of the patient, physiological system state, organ state, physiological part state and tissue state is/are abnormal or not, and one or more of an abnormality level, a criticality level, and a nursing level. An exemplary description is given below in conjunction with
As shown in
In addition, state information A1 and B1 of the physiological parts A and B are displayed adjacent to the human body diagram (peripheral area). In the example shown in
In an embodiment of this disclosure, presenting in the combined alarm mode, by the unit for details of a patient state 4202, at least one item of alarm information which is associated with the patient state, may include combining an alarm for exceeding a threshold of and/or an alarm for an event, for the at least one physiological parameter signal, which parameter is associated with the patient state, with duration(s) of the alarm for exceeding a threshold and/or the alarm for an event; and presenting the alarm for exceeding a threshold and/or the alarm for an event and the duration(s) of the alarm for exceeding a threshold and/or the alarm for an event. In addition, a duration of an alarm can also be other time information of said alarm, such as interval time of said alarm, occurrence frequency within unit time, etc. Wherein it is also possible that, when the duration(s) of the alarm(s) exceed(s) preset time length(s), the alarm for exceeding a threshold of and/or the alarm for an event, for the at least one physiological parameter signal, which parameter is associated with the patient state, are/is combined with the preset time length(s), and then presented with the preset time length. Wherein the alarm for exceeding a threshold refers to an alarm which satisfies an alarm rule for exceeding a threshold. The alarm rule for exceeding a threshold may include that a certain parameter value exceeds its preset threshold. The alarm for an event refers to an alarm for an abnormal event. For example, an alarm for an abnormal event is outputted when a patient is determined to be in an abnormal state by analysing one or more physiological parameters. At least one item of alarm information, which is associated with the patient state and presented in the combined alarm mode, can be presented via text. The alarm and its time information can be presented in a combined manner, so as to jointly reflect one or more of the overall state of the patient, the same physiological system state, the same organ state, the same physiological part state, and the same tissue state. Herein, the alarm and time information can be presented in a combined manner, can be understood as using hyphen(s) (such as commas, semicolons, etc.), connecting word(s) (such as “and”, “also”, “with”, etc.) to combine and present the alarm and alarm-related time information, so as to form combined alarm information.
Compared with non-combined alarm information that does not include time information, the combined alarm information can present more detailed alarm information to medical staff in multiple dimensions. So that medical staff can have a clearer understanding of the patient condition. It should be understood that the associated character string is not limited to the examples disclosed in this disclosure, and may be any other character string as long as it can reflect that the presented information is one or more alarms and time information thereof. Wherein it is possible to display in the combined alarm mode, on the display 30, the at least one item of alarm information, which is associated with the patient state, when the duration of the alarm exceeds a preset time length. In this way, the presentation of some alarm information in the case where the alarm rule is briefly satisfied but soon not satisfied on its own, can be ignored, so that medical staff can only focus on the alarm information, which requires more attention and is of long duration.
In another embodiment, the physiological parameter signal of at least one physiological parameter signal of the patient includes a first physiological parameter signal and a second physiological parameter signal, and the processor 20 is further configured to control the display to simultaneously present the first alarm information and the second alarm information in an associated combination mode, when determining that the first physiological parameter satisfies the first alarm rule and the second physiological parameter satisfies the second alarm rule. For example, the second alarm rule includes: the second physiological parameter signal satisfies the alarm rule for exceeding a threshold and/or the alarm rule for an event; and duration(s) exceed(s) preset time length(s), in which duration(s) the second physiological parameter satisfies the alarm rule for exceeding a threshold and/or the alarm rule for an event. Alternatively, the second alarm rule includes: the second physiological parameter signal satisfies the alarm rule for exceeding a threshold and/or the alarm rule for an event. The first alarm information represents that the first physiological parameter satisfies the first alarm rule, and the second alarm information represents that the second physiological parameter satisfies the second alarm rule. At least one item of alarm information, which is associated with the patient state and presented in the combined alarm mode, can be presented via text. The first alarm rule may be an alarm rule for exceeding a threshold and/or an alarm rule for an abnormal event, which alarm rule(s) is(are) associated with the first physiological parameter; wherein a first alarm for exceeding a threshold and/or a first alarm for an abnormal event, occurs simultaneously with a second alarm for exceeding a threshold and/or a second alarm for an abnormal event. In this embodiment, the unit for details of a patient state 4202 presents two alarms which respectively correspond to two physiological parameter signals, wherein the two alarms are presented in a combined mode, and jointly reflect one or more of the overall state of the patient, the same physiological system state, the same organ state, the same physiological part state, and the same tissue state. Here, two alarms are presented as a group, which is also a kind of combined alarm information, and can present related alarm information to medical staff, so that medical staff can understand the patient condition more clearly.
Furthermore, the aforementioned presenting, via text, at least one item of alarm information, which is associated with the patient state and presented in the combined alarm mode, includes combing and presenting followings: a first alarm for exceeding a threshold and/or a first alarm for an abnormal event, for a first physiological parameter, which parameter is associated with the patient state; a second alarm for exceeding a threshold and/or a second alarm for an abnormal event, for a second physiological parameter, which parameter is associated with the patient state; and a duration in which: the first alarm for exceeding a threshold and/or the first alarm for an abnormal event, and the second alarm for exceeding a threshold and/or the second alarm for an abnormal event, simultaneously occur. In this embodiment, the unit for details of a patient state 4202 presents two alarms which respectively correspond to two physiological parameters and the durations of the two alarms, which jointly reflect one or more of the overall state of the patient, the same physiological system state, the same organ state, the same physiological part state, and the same tissue state. Here, two alarms and the durations thereof are presented as a group, which is also a kind of combined alarm information, and can present related alarm information to medical staff, so that medical staff can understand the patient condition more clearly.
As shown in
Furthermore, in other examples, at least one item of alarm information, which is associated with the patient state and presented in the combined alarm mode, can be presented via graph. For example, at least one item of alarm information, which is associated with the patient state and presented in the combined alarm mode, can be presented via a curve graph, a histogram, a bar graph, a box graph, a scatter graph, a broken line graph, or a combination thereof, so that medical staff can more intuitively understand changes in the physiological parameter itself and/or changes in the comparison result of the physiological parameter with the preset alarm condition.
In an embodiment of this disclosure, the processor 120 may also control the display 130 to present a trend graph of at least one physiological parameter signal in a preset time period, wherein the trend graph is configured to reflect an evolution situation of the at least one physiological parameter signal in the preset time period. For example, the patient state window 420 further includes a display unit for a change of physical sign that presents a trend graph in a preset time period for at least one physiological parameter signal (such as the physiological parameter signal presented in the unit for details of a patient state 4202 or other physiological parameter(s)). This trend graph is configured to reflect an evolution situation of the physiological parameter in the preset time period, which allows medical staff to have a more detailed understanding of the evolution situation of the physiological parameter, which is associated with the current patient state. The trend graph of the physiological parameter may include a trend graph of a parameter value of the physiological parameter (for example, a heart rate value), or may include trend graphs of some abnormal events, which correspond to the physiological parameter (for example, an arrhythmia event corresponding to the electrocardiogram parameter, such as atrial fibrillation, ventricular fibrillation, etc.). In the example shown in
In order to facilitate the setting of upgraded alarm which is presented in the combined alarm mode, so that the user can adjust as needed one or more of the combined alarms that need to be alarmed,
Optionally, the first alarm rule includes an alarm rule for exceeding a threshold and/or an alarm rule for an abnormal event, which alarm rule(s) is(are) associated with a first physiological parameter in the at least one physiological parameter signal; the second alarm rule includes an alarm rule for exceeding a threshold and/or an alarm rule for an abnormal event, which alarm rule(s) is(are) associated with a second physiological parameter, wherein the second physiological parameter is different from the first physiological parameter.
In order to facilitate the user to adaptively adjust the alarm rule for the combined alarm, when at least one of the first alarm rule and the second alarm rule includes an alarm rule for exceeding a threshold, the processor is further configured to adjust an alarm threshold of the alarm rule for exceeding a threshold, when receiving an instruction for adjusting the alarm threshold. For example, the instruction for adjusting the alarm threshold can be inputted by operating the control for an alarm threshold, so as to adjust the alarm threshold of the alarm rule for exceeding a threshold to a threshold which is instructed by said instruction.
