In order to provide a thorough understanding of the present application, a detailed structure will be presented in the following description in order to explain the technical solutions presented in the present application. Alternative embodiments of the present application are described in detail below, however, the present application may have other implementations in addition to these detailed descriptions.
In the following, referring first to fig. 1, a monitoring method 100 according to an embodiment of the present application is described, the monitoring method 100 being used for a monitoring device, such as a monitor or a central monitoring management system. As shown in fig. 1, the monitoring method 100 may include the following steps:
in step S110, acquiring physiological sign data of a physiological characteristic parameter of a monitored subject; the physiological sign data may include numerical values, and may also include waveform information, trend information, and the like.
In step S120, analyzing the acquired physiological characteristic data to identify physiological characteristic data in an abnormal state;
in step S130, counting, in real time, a total duration of the physiological characteristic data in the abnormal state within a preset time period, where the total duration includes at least one duration of the physiological characteristic data in the abnormal state;
in step S140, displaying the acquired physiological characteristic data on a display interface of the monitoring device, and displaying the total duration counted in real time or the proportion of the total duration in the preset time period in a region adjacent to the displayed physiological characteristic data; or when the total duration time exceeds a first preset threshold value or the proportion of the total duration time in the preset time period exceeds a second preset threshold value, alarm information is output on a display interface of the monitoring equipment.
The monitoring method 100 of the embodiment of the invention counts the total duration of the physiological characteristic data in the abnormal state within the preset time period, displays the total duration or the proportion (namely load) of the total duration, or alarms according to the total duration or the proportion, and compared with the traditional monitoring method which determines whether to alarm or not according to the duration of a single-stage abnormal state, the monitoring method can highlight the abnormal degree of the physiological characteristic data within the preset time period, help medical staff to master the development and change of the illness state of the monitored object within the preset time period, so as to better formulate a treatment scheme.
For some monitored subjects with specific disease types or monitored subjects with disease conditions in a certain development period, the embodiment of the invention can help medical staff to pay attention to the total duration of abnormal physiological characteristic data of the monitored subjects in a period of time, for example, for an aortic dissection monitored subject, blood pressure needs to be paid attention all the time, not only transient blood pressure is too high or too low, but also medical intervention is needed, and the total duration of blood pressure too high or too low in a period of time is too long, and medical intervention can also be needed. Whether the medical intervention is needed or not can be reflected by counting the total duration time that the physiological characteristic data are in the abnormal state (for example, the blood pressure is too high or too low), the postoperative effect or the medical intervention effect at a certain moment of the monitored object can be reflected, subsequent treatment is carried out according to the medical intervention effect, and the improvement or the maintenance of the current treatment scheme is determined.
To better match user requirements, the anomaly statistics of the embodiment of the present invention may be implemented as a configurable process, and illustratively, the total duration of abnormal state of the physiological characteristic data within a preset time period may be counted in real time under at least one of the following conditions: starting real-time statistics when an instruction for starting the real-time statistics is detected; starting to carry out real-time statistics when physiological characteristic data are detected to be abnormal for the first time; and starting to carry out real-time statistics when the physiological characteristic data abnormality is detected in the preset time period.
The physiological characteristic data of the monitored object obtained in step S110 may include data of various physiological characteristic parameters such as a blood pressure parameter, a respiration parameter, an electrocardiographic parameter, a blood oxygen parameter, and a body temperature parameter. When the physiological characteristic parameter is an electrocardiographic parameter, the abnormal state of the physiological characteristic data identified in step S120 may include an atrial fibrillation arrhythmia event, and the atrial fibrillation load (atrial fibrillation load for short) is a ratio of the total duration counted according to the atrial fibrillation arrhythmia event to a preset time period. Further, since the embodiment of the present invention obtains the total duration by counting the durations of the plurality of individual segments of the physiological characteristic data, the length of each individual segment duration may be very short, and thus the identified atrial fibrillation arrhythmia events may be short-matrix atrial fibrillation arrhythmia events, that is, atrial fibrillation arrhythmia events having a duration of 30 seconds to 60 seconds. By counting the duration of the atrial fibrillation arrhythmia events occurring within the preset time period, medical care personnel can be helped to master the state of illness change of the monitored object, and the treatment method can be adjusted in time according to the state of illness change.
In step S130, for a single physiological characteristic parameter, the total duration of the physiological sign data is the sum of the durations of a plurality of single segments. Referring to fig. 2, for example, atrial fibrillation arrhythmia, atrial fibrillation load is the proportion of the total duration of atrial fibrillation within a preset time period, that is:
T1＝t1+t2+t3+…+tn
wherein,
1) t represents the duration of a preset time period;
2) t 1-tn represents the duration of each atrial fibrillation arrhythmia event;
3) t1 represents the overall duration of an atrial fibrillation arrhythmia event over a preset period of time;
4) p represents the atrial fibrillation burden, i.e. the proportion of the total duration that is within a preset time period.
For other types of physiological characteristic parameters, the overall duration and its load may also be counted in a similar manner to atrial fibrillation arrhythmia events.
If a plurality of physiological characteristic parameters are concerned, the physiological characteristic data acquired in step S110 may include physiological sign data of at least two physiological characteristic parameters, and the physiological sign data of each physiological characteristic parameter is analyzed in step S120 to identify an abnormal state thereof; when the total duration of the abnormal state of the physiological characteristic data in the preset time period is counted in real time in step S130, the following two implementation manners may be adopted: one is to separately count the overall duration of the physiological sign data of each physiological characteristic parameter, and the second is to sum the overall duration of the physiological sign data of at least two physiological characteristic parameters. When the overall duration of the physiological sign data of each physiological characteristic parameter is individually counted, the counting method is the same as the counting method of the physiological sign data of the single physiological characteristic parameter described above. When the total duration of the physiological sign data of at least two physiological characteristic parameters is subjected to summary statistics, the statistical method described below can be adopted.
If the at least two physiological characteristic parameters belong to the same class of physiological characteristics, the total duration of the physiological sign data of the at least two physiological characteristic parameters belonging to the same class of physiological characteristics can be summarized and counted. The physiological characteristic parameters belonging to the same class of physiological characteristics, such as systolic pressure, diastolic pressure and average pressure, all belong to blood pressure parameters, and the physiological characteristic parameters belonging to the same class of physiological characteristics have relevance, so that the abnormal conditions of the physiological sign data can be summarized and counted. When the physiological sign data of the physiological characteristic parameters belonging to the same class of physiological characteristics are collected and counted, the average value of the total duration time of the physiological sign data of at least two physiological characteristic parameters belonging to the same class of physiological characteristics can be counted, and the parameter load is calculated according to the proportion of the average value in a preset time period.
Referring to fig. 3, taking three blood pressure parameters of systolic pressure, diastolic pressure and mean pressure as an example, when summarizing the total duration:
Ts＝ts1+ts2+ts3+…+tsn1
Td＝td1+td2+td3+…+tdn2
Tm＝tm1+tm2+…+tmn3
wherein,
1) t represents the duration of a preset time period;
2) ts1 to tsn1, td1 to tdn2, and tm1 to tmn3 respectively indicate single-stage durations during which the systolic pressure, the diastolic pressure, and the average pressure are abnormal;
3) ts, Td, Tm respectively represent the total duration of abnormal systolic pressure, diastolic pressure, and mean pressure;
4) p represents the loading of the blood pressure parameter, i.e. the ratio of the mean of the systolic pressure, the diastolic pressure, the total duration of the abnormal state of the mean pressure, to a preset time period.
Furthermore, depending on the physiological characteristic parameter of interest, all physiological characteristic parameters belonging to the same class of physiological characteristics may be counted, or only a part of the physiological characteristic parameters belonging to the same class of physiological characteristics may be counted, for example, only the total duration of abnormal states in the data of the systolic pressure and the diastolic pressure, only the total duration of abnormal states in the data of the systolic pressure and the average pressure, or only the total duration of abnormal states in the data of the diastolic pressure and the average pressure.
In addition to the summary statistics of the physiological data of the physiological characteristic parameters belonging to the same class of physiological characteristics, in some embodiments, the summary statistics of the overall duration of the physiological data of the physiological characteristic parameters belonging to at least two classes of physiological characteristics can also be performed. Wherein the at least two types of physiological characteristic parameters may be homologous physiological characteristic parameters. For example, the heart beats to generate an electrocardio signal, the heart beats to pump blood to the whole body to generate a blood pressure signal, and the blood oxygen signal is obtained by picking up the blood pressure signal at the end of blood flow transmission, so that the electrocardio parameters, the blood pressure parameters and the blood oxygen parameters can be considered as homologous physiological characteristic parameters.
In addition, some physiological characteristic parameters are not direct homologous parameters but have correlation, so that the physiological sign data of at least two types of physiological characteristic parameters with correlation can be subjected to summary statistics. For example, electrocardio signals and respiratory signals, body temperature signals, wherein the respiratory signals are derived from respiration and can be picked up from the fluctuation of the thorax or the exhalation of the nasal cavity; the body temperature signal comes from the body surface or the oral cavity or the armpit and can be picked up through temperature detection; however, in a specific scene, there is a certain correlation between the electrocardiographic signal, the respiratory signal and the body temperature signal, and for example, in a cold condition, a plurality of physiological characteristic data of accelerated heartbeat, accelerated respiration and decreased body temperature are abnormal together.
Therefore, in order to improve the accuracy of the load of a single physiological characteristic parameter, and to highlight the relevance of the loads of two or more physiological characteristic parameters, and to assist medical personnel to better master the disease development of the monitored object, the embodiment of the invention also supports the summary statistics of the physiological sign data of the physiological characteristic parameters belonging to the same source or the physiological characteristic parameters with the relevance, and jointly prompts the current disease development of the monitored object, thereby increasing the monitoring reliability.
Optionally, when the overall duration of the physiological sign data of the homologous physiological characteristic parameters or the physiological characteristic parameters with correlation is summarized and counted, the overall duration of the physiological sign data of at least two types of physiological characteristic parameters in an abnormal state at the same time can be counted to reduce parameter load inaccuracy caused by the problem of monitoring quality. Specifically, as shown in fig. 4, wherein:
Tp＝Δt1+Δt2+…+Δtp
where Δ ti (i is 1 to P) represents a single duration in which data of three parameters are simultaneously in an abnormal state, Tp is an overall duration obtained by counting the single durations, and P is a parameter load.
Referring to fig. 5, a portion of the physiological characteristic parameter load that may be counted according to the above method is shown.
After the total duration and the proportion of the total duration in the preset time period are obtained through statistics, step S140 provides two schemes of displaying and alarming based on the total duration and the proportion of the total duration in the preset time period. The display scheme is to display the acquired physiological characteristic data on a display interface of the monitoring device, and display the total duration counted in real time or the proportion of the total duration in a preset time period in the vicinity of the displayed physiological characteristic data. The alarm scheme is that when the total duration exceeds a first preset threshold or the proportion of the total duration in a preset time period exceeds a second preset threshold, alarm information is output on a display interface of the monitoring equipment. The medical staff can know the disease development of the monitored object by displaying the total duration or the proportion of the total duration in the preset time period, and the medical staff can pay attention by outputting alarm information and provide medical access when necessary.
Fig. 6 illustrates a display interface of the monitoring device with blood pressure load as an example. In the example of fig. 6, the display interface of the monitoring device includes a waveform trend area 601 and a waveform value area 602, the waveform trend area 601 is used for displaying the waveform of the physiological characteristic parameter, and the waveform value area 602 is used for displaying the value of the physiological characteristic parameter. The total duration or the ratio of the total duration or the total duration counted in step S130 in the preset time period (i.e., "systolic/diastolic/average pressure load: 10%/25%/53%" in fig. 6) can be displayed in the waveform value region 602 of the corresponding physiological characteristic parameter as shown in fig. 6, or can be displayed in the waveform trend region 601.
Further, displaying the total duration or the proportion of the total duration in the preset time period includes: and displaying the overall duration in different forms according to whether the overall duration exceeds a first preset threshold, or displaying the proportion in different forms according to whether the proportion of the overall duration in a preset time period exceeds a second preset threshold. Different forms may be implemented as different colors, sizes, brightness, locations, etc. The first preset threshold and the second preset threshold may be the above threshold for determining whether to output the alarm information, that is, when the data abnormality degree of the physiological characteristic parameter is serious, the total duration or the proportion of the total duration in a preset time period is displayed in different forms to remind the medical staff of paying attention.
In another embodiment, the display interface of the monitoring device includes a waveform trend region, a waveform value region, and an alarm information region. Displaying the overall duration includes: and when the total duration time exceeds a first preset threshold value, displaying the total duration time in an alarm information area of the monitoring interface, a waveform trend area corresponding to the physiological characteristic parameter or a waveform numerical value area corresponding to the physiological characteristic parameter. Displaying the proportion of the total duration in the preset time period comprises: and when the proportion of the total duration in the preset time period exceeds a second threshold value, displaying the proportion of the total duration in the preset time period in an alarm information area, a waveform trend area corresponding to the physiological characteristic parameter or a waveform numerical value area corresponding to the physiological characteristic parameter. In this embodiment, the overall duration or the proportion of the overall duration within a preset time period is only displayed if it exceeds the corresponding alarm threshold. And meanwhile, the alarm information can be output.
When the total duration time exceeds a first preset threshold value or the proportion of the total duration time in a preset time period exceeds a second preset threshold value, namely the abnormal degree of the physiological characteristic data is serious, alarm information is output to remind medical staff of paying attention, and the monitored object possibly needs medical intervention at present. The alarm information may include sound information, vibration information, and the like.
In some embodiments, in order to monitor the change of the parameter load in real time and remind the medical staff in time when the load is high, alarm thresholds of a plurality of gears may be set, that is, the first preset threshold and/or the second preset threshold may include a plurality of thresholds. When the total duration exceeds different first preset thresholds and/or the proportion of the total duration in a preset time period exceeds different second preset thresholds, different alarm information can be output.
Alternatively, the alarm thresholds of a plurality of gears may be applied to the display scheme, that is, when the total duration exceeds a first preset threshold, and/or the proportion of the total duration in the preset time period exceeds a second preset threshold, the total duration or the proportion of the total duration in the preset time period is displayed in different forms. For example, a red display, a "beep" audible cue when the overall duration exceeds a high level threshold; a yellow display, beeping to sound when the overall duration exceeds a medium threshold; the overall duration exceeds the low level threshold and is displayed in green, and is audibly prompted by a "beep". Different thresholds can be determined according to medical care requirements and can be dynamically adjusted.
The embodiment of the invention also supports the review and check of the total duration or the parameter load, and displays the total duration or the parameter load in the review time by taking the preset time period as a unit according to the set review time length so as to facilitate the guardian to determine the development trend of the condition of the monitored object. Specifically, when a review instruction is received, the total duration or the proportion of the total duration in a plurality of preset time periods in the review time within the preset time period is displayed through characters or graphs.
The characters can be in a form of a table, and the graphics can be at least one of the following: histograms, curve trend plots, and K-line plots. When the total duration of each preset time period or the proportion of the total duration in the preset time period in the review time is displayed in a graph form, the first preset threshold or the second preset threshold can be marked on the graph, so that medical personnel can conveniently know the distribution condition of one or more physiological characteristic parameters of the monitored object in the review time and adjust the medical scheme in time.
Fig. 7 shows a histogram for reviewing blood pressure load, wherein the abscissa represents preset time periods in each of which the load of systolic, diastolic and average blood pressure is counted, respectively. The second preset thresholds shown in fig. 7 include three, which are respectively 10, 30 and 50 from bottom to top, and each of the second preset thresholds is marked by a horizontal line. Alternatively, when displaying the histogram, the horizontal lines corresponding to different preset thresholds may be displayed in different colors, for example, as green lines, yellow lines, and red lines, respectively.
Fig. 8 shows a curve trend of the blood pressure load corresponding to fig. 7, the three curves in the curve trend representing the parametric load of systolic, diastolic and mean pressures, respectively.
The histograms and graphs described above may support review of multiple physiological characteristic parameters, while the K-line plot supports primarily a data review of a single physiological characteristic parameter, and fig. 9 shows a K-line plot of systolic pressure loading. When the graph is a K-line graph, the K-line cells indicating increase and the K-line cells indicating decrease in the K-line graph may be displayed in different colors or patterns, for example, a red rectangle may indicate that the systolic pressure is increased for the current preset time period compared to the last preset time period, and a green rectangle may indicate that the systolic pressure load is decreased for the current preset time period compared to the last preset time period.
In addition, when the difference between the total duration in a certain preset time period and the total duration in the previous preset time period exceeds a third preset threshold, or the difference between the proportion in the certain preset time period and the proportion in the previous preset time period exceeds a fourth preset threshold, the K-line unit corresponding to the preset time period can be highlighted, so that medical staff can conveniently position the preset time period in which the parameter load is increased or decreased more quickly, evaluate whether the treatment scheme in the period is effective, and determine whether to adjust the treatment scheme.
In addition, the physiological characteristic data measured by the monitoring device is limited by the quality of the parameter accessory, the connection quality of the accessory, the position of the accessory sensor for acquiring the physiological signal and the like, all of which have an influence on the monitoring quality of the physiological parameter, and if a non-physiological signal (noise) is introduced because the monitoring quality is not good, for example, the accessory is not well worn, the measurement result of the physiological characteristic parameter is unreliable, and the parameter load obtained by statistics according to the unreliable measurement result is also unreliable.
Therefore, in one embodiment, the technical alarm occurring when the physiological characteristic data is in an abnormal state within a preset time period can be counted in real time; and simultaneously displaying the technical alarm in the review time on the text or the graph of the total duration or the proportion of the total duration of the displayed physiological characteristic data in the preset time period. The technical alarm is also called system error information, and refers to an alarm that a certain monitoring function cannot normally operate or a monitoring result is distorted due to improper operation or system failure. In contrast, the alarm information output according to the overall duration of the physiological characteristic data described above belongs to a physiological alarm. By displaying the technical alarm during the review, the method can help the user to eliminate the physiological characteristic parameter abnormity caused by the monitoring quality problem and improve the monitoring accuracy.
Based on the above description, the monitoring method 100 according to the embodiment of the present invention can help the medical staff to grasp the development and change of the physiological characteristic data of the monitored object in the preset time period by counting the total duration of the abnormality of the physiological characteristic data in the preset time period, so as to better perform the monitoring.
In the following, a monitoring method 1000 according to another embodiment of the present application is described with reference to fig. 10, the monitoring method 1000 being for a monitoring device.

As shown in fig. 10, the monitoring method 1000 includes the following steps:
in step S1010, acquiring physiological sign data of a physiological characteristic parameter of a monitored subject;
in step S1020, whether the acquired physiological characteristic data is in a normal state is analyzed;
in step S1030, counting, in real time, a total duration of the physiological characteristic data in the normal state within a preset time period, where the total duration includes at least one duration of the physiological characteristic data in the normal state;
in step S1030, displaying the total duration or a proportion of the total duration in the preset time period; or when the total duration is lower than a first preset threshold or the proportion of the total duration in the preset time period is lower than a second preset threshold, outputting alarm information.
The monitoring method 1000 of the present embodiment is different from the monitoring method 100 described above in that the monitoring method 1000 of the present embodiment counts the total duration of the physiological characteristic data in the normal state, and accordingly outputs the alarm information when the total duration is lower than the first preset threshold or the ratio of the total duration in the preset time period is lower than the second preset threshold. In addition, the steps of the monitoring method 1000 are substantially similar to the monitoring method 100, and reference is made to the above description for details, which are not repeated herein.
