The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that the embodiments described herein may be practiced otherwise than as specifically illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The CVP2-5 principle is a commonly used judgment principle in clinical practice, namely: the rapid fluid infusion is carried out within 10 minutes by 100-200ml, if the CVP is increased by less than 2mmHg, the patient is indicated to have volume reactivity, and the fluid infusion can be continued. When CVP increased to between 2-5mmHg, fluid replacement was suspended and whether CVP could be restored was observed. When CVP increases by more than 5mmHg, this indicates that the patient is at risk of volume overload and fluid replacement should be terminated.
The following describes in detail the method for monitoring physiological signs of fluid infusion, and it should be noted that the monitoring device mentioned in the present invention is not limited to a monitor, but also includes an invasive/noninvasive ventilator, an anesthesia machine, a defibrillator, a nurse station, a central station, etc. with a monitoring function.
Referring to fig. 1, fig. 1 is a schematic flow chart of a physiological sign monitoring method for fluid infusion in the present embodiment, including:
In this embodiment, the monitoring device may acquire the collected signal of the central venous pressure of the monitored object under the condition of fluid infusion through a measurement device connected to a human body, convert the collected signal of the central venous pressure of the monitored object under the condition of fluid infusion into an electrical signal, perform preprocessing such as interference suppression, signal filtering and amplification, and finally acquire the monitoring data of the central venous pressure of the monitored object under the condition of fluid infusion.
The central venous pressure is the pressure of the superior and inferior vena cava entering the right atrium, is measured by the superior and inferior vena cava or right atrial indwelling catheter, reflects the right atrial pressure, and is one of the main indexes for clinical observation of hemodynamics. It is generally used as an index of fluid infusion speed and fluid infusion amount in clinical practice.
And 102, generating central venous pressure trend information according to the central venous pressure monitoring data.
In this embodiment, after the monitoring device obtains the central venous pressure data of the monitored object under the condition of fluid infusion through the measuring device connected to the human body, since the central venous pressure monitoring data of the monitored object under the condition of fluid infusion usually changes continuously along with the lapse of time, the monitoring device can store the central venous pressure monitoring data of the monitored object under the condition of fluid infusion, which is obtained within a preset time period, so as to obtain the central venous pressure trend information of the monitored object.
It should be noted that the central venous pressure trend information may display monitoring data of the central venous pressure within a preset time period (for example, 30 minutes), and may also be set according to actual situations, which is not limited specifically.
And 103, displaying a special tool interface for the liquid supplementing condition in the main monitoring interface.
In this embodiment, the monitoring device may provide a main monitoring interface, and generate a special tool interface for displaying the fluid infusion condition of the monitored object on the main monitoring interface.
Generally, a main monitoring interface of a conventional monitoring device displays various conventional physiological sign waveform information, and medical care personnel need to find CVP data needing to be concerned from complicated information, so that the medical care personnel cannot intuitively and efficiently obtain data information needing to be concerned when judging a fluid infusion condition. In this embodiment, when the medical care personnel need to pay attention to the data information of the CVP, a special tool interface for fluid infusion is displayed in the main monitoring interface, and the medical care personnel can intuitively acquire the desired CVP data information by observing the special tool interface. Specifically, the tool interface for fluid infusion can be popped up from the main monitoring interface after the user touches the CVP tool icon of the main monitoring interface.
For example, referring to fig. 2, fig. 2 is a schematic diagram of a hemodynamic monitoring interface of a monitoring device, and fig. 3 is a schematic diagram of a tool interface for fluid replacement according to an embodiment of the present invention, wherein an operation instruction of a user, i.e., an operation instruction for the CVP2-5 tool in the area 201, can be received at the hemodynamic monitoring interface, and the tool interface for fluid replacement shown in fig. 3 is generated and displayed.
It can be understood that the fluid replacement condition specific tool interface may be embedded in a display area of the main monitoring interface, or may be suspended on the main monitoring interface; the fluid replacement condition specific tool interface covers or does not cover other contents displayed on the main monitoring interface.
And 104, displaying central venous pressure trend information in the interface of the special tool for fluid infusion.
In this embodiment, after the main monitoring interface displays the interface of the special tool for fluid infusion, the monitoring device may display the central venous pressure trend information of the monitored object in the interface of the special tool for fluid infusion. The central venous pressure trend information may include at least one of a central venous pressure trend table and a central venous pressure trend graph, and it can be understood that, in this embodiment, the central venous pressure trend graph of the monitoring object displayed on the fluid infusion condition dedicated tool interface is mainly described as an example.
Continuing to refer to fig. 3, an interface 301 is the above-mentioned interface of the tool for fluid infusion, and 302 is a central venous pressure trend graph of the monitored subject during fluid infusion within a preset time period.
And 105, refreshing central venous pressure trend information displayed in the interface of the special tool for fluid infusion based on the acquired new central venous pressure monitoring data.
In this embodiment, since the central venous pressure monitoring data of the monitoring object under the condition of fluid infusion changes in real time, after the central venous pressure trend information is displayed on the interface of the fluid infusion condition-specific tool, the monitoring device continues to monitor the central venous pressure of the monitoring object in real time through the measuring device, generates central venous pressure trend information, and refreshes the central venous pressure trend information displayed on the interface of the fluid infusion condition-specific tool according to the newly generated central venous pressure trend information. That is, the central venous pressure trend information in the fluid replacement situation-specific tool interface always shows the central venous pressure trend information of the monitoring object acquired in the latest period of time (for example, within 30 minutes).
In order to assist the medical staff in judging the fluid infusion condition, a fluid infusion baseline corresponding to the monitored object may be generated and displayed on the central venous pressure trend graph, and a value corresponding to the fluid infusion baseline may also be set, for example, a measured value of the central venous pressure when the special tool interface for the fluid infusion condition is opened may be used as a value corresponding to the fluid infusion baseline, or a value corresponding to the fluid infusion baseline may be determined based on configuration information input by the user.
It can be understood that, after the fluid infusion baseline corresponding to the monitored object is generated and displayed on the central venous pressure trend graph, a first identification line and/or a second identification line may be generated and displayed in the central venous pressure trend graph, the first identification line and the second identification line have an association relationship with the fluid infusion baseline, and a numerical value corresponding to the first identification line is smaller than a numerical value corresponding to the second identification line, and a numerical value corresponding to the fluid infusion baseline is smaller than a numerical value corresponding to the first identification line. That is to say, the first identification line and the second identification line are two identification lines that are set on the basis of the fluid infusion baseline, and it can be understood that the numerical values corresponding to the first identification line and the second identification line can also be determined based on the configuration information input by the user. The following description is made with reference to fig. 3:
referring to fig. 3, 302 is a central venous pressure trend graph under the condition of fluid infusion of a monitored subject, 303 is a fluid infusion baseline corresponding to the monitored subject, 304 is a first identification line, 305 is a second identification line, wherein the first identification line and the second identification line have an association relationship with the setting of the fluid infusion baseline, for example, the value corresponding to the first identification line is +2mmHg corresponding to the fluid infusion baseline, that is, 2mmHg is added on the basis of the value corresponding to the fluid infusion baseline; the numerical value corresponding to the second identification line is +5mmHg of the numerical value corresponding to the fluid infusion baseline, namely 5mmHg is added on the basis of the numerical value corresponding to the fluid infusion baseline. It is understood that the values corresponding to the fluid replacement baseline, the first identification line and the second identification line may be set by a doctor or a nurse according to the actual situation of the monitored object, and the above description is only an example and does not represent a limitation on the values corresponding to the first identification line and the second identification line.
The following explains how to judge the fluid infusion condition of the monitoring object by the central venous pressure trend information of the monitoring object and based on the fluid infusion baseline and the first identification line and/or the second identification line.
The monitoring equipment can measure the measured value of the central venous pressure of the monitored object in real time through the measuring device, and generates first prompt information when the measured value of the central venous pressure of the monitored object exceeds a numerical value corresponding to the first identification line; and/or determining that second prompt information distinguished from the first prompt information is generated when the measured value of the central venous pressure of the monitored object exceeds the value corresponding to the second identification line. Wherein: the first prompt message comprises notification information indicating that fluid replacement of the monitored object needs to be suspended, and the second prompt message comprises notification information indicating that fluid replacement of the monitored object needs to be terminated.
With reference to fig. 3, in the process of fluid infusion of the monitored object, the monitoring device may obtain central venous pressure trend information of the monitored object in real time, and display the central venous pressure trend information in the form of a trend graph (see 302 in fig. 3) on the fluid infusion condition dedicated tool interface, and the first identification line (see 304 in fig. 3) and the second identification line (see 305 in fig. 3) are also displayed on the fluid infusion condition dedicated tool interface, and may send out a prompt message according to the intersection condition of the measured value of the central venous pressure of the monitored object and the first identification line or the second identification line, and the following description is given by taking the first identification line as a value +2mmHg corresponding to the fluid infusion baseline, and the second identification line as a value +5mmHg corresponding to the fluid infusion baseline:
if the measured value of the central venous pressure of the monitored object at the current moment exceeds the first identification line, namely the measured value of the central venous pressure of the monitored object at the current moment is higher than a value corresponding to the fluid infusion baseline by +2mmHg, sending first prompt information, and prompting to suspend fluid infusion on the monitored object by the first prompt information;
and if the measured value of the central venous pressure of the monitored object at the current moment exceeds the second identification line, namely the measured value of the central venous pressure of the monitored object at the current moment is higher than the value corresponding to the fluid infusion baseline by +5mmHg, sending second prompt information, wherein the second prompt information indicates that fluid infusion is stopped for the monitored object.
It should be noted that, in addition to acquiring the central venous pressure monitoring data of the monitored subject under the fluid infusion condition, the monitoring device may also acquire the physiological sign monitoring data associated with the fluid infusion condition of the monitored subject, where the physiological sign associated with the fluid infusion condition includes at least one of heart rate, arterial pressure (Art), non-invasive blood pressure (NIBP), blood oxygen, and blood flow perfusion index. Specifically, the displayed blood oxygen monitoring data may be a blood oxygen saturation trend graph, a blood oxygen saturation measurement value, and the like.
In addition, after monitoring the physiological sign monitoring data of the monitored object associated with the fluid replacement condition, the monitoring device may generate a waveform diagram and/or numerical information corresponding to the physiological sign associated with the fluid replacement condition based on the physiological sign monitoring data associated with the fluid replacement condition, display the waveform diagram and/or numerical information corresponding to the physiological sign associated with the fluid replacement condition on the fluid replacement condition dedicated tool interface, and refresh the waveform diagram and/or numerical information corresponding to the physiological sign associated with the fluid replacement condition displayed on the fluid replacement condition dedicated tool interface based on the obtained new physiological sign monitoring data associated with the fluid replacement condition.
Referring to fig. 3, the physiological signs related to the fluid replacement condition are, for example, a heart rate and an arterial pressure, please refer to fig. 3, where 306 is a heart rate trend graph in the fluid replacement condition of the monitored subject within a preset time period, 308 is real-time numerical information of the heart rate in the fluid replacement condition of the monitored subject (for example, "65" shown in fig. 3), 307 is an arterial pressure trend graph in the fluid replacement condition of the monitored subject within the preset time period, 309 is real-time numerical information of the arterial pressure in the fluid replacement condition of the monitored subject (for example, "130/80" shown in fig. 3), and of course, changes of monitoring data of other physiological signs related to the fluid replacement condition of the monitored subject (not shown in fig. 3) are also provided, and for convenience of description, the descriptions are omitted. It can be understood that the process of monitoring the physiological characteristics of the monitored object associated with the fluid replacement condition by the monitoring device is similar to the process of monitoring the central venous pressure monitoring data, which has been described above specifically, and is not described herein again specifically.
It should be further noted that, when the fluid replacement situation-specific tool interface displays at least the central venous pressure trend graph and/or the waveform graph corresponding to the physiological characteristic associated with the fluid replacement situation (the waveform graph includes the physiological sign simulation signal waveform graph and the physiological sign trend graph), a time line may be generated and displayed in the trend graph and/or the waveform graph, and the measured values of the central venous pressure and/or the physiological sign associated with the fluid replacement situation at the time point corresponding to the time line may be displayed in response to the operation of the user on the fluid replacement situation-specific tool interface. It is understood that the trend graph and the waveform graph are identified by the same coordinate system, and the time axes of the trend graph and the waveform graph are consistent. The following describes operation of the specialized tool interface in response to a user's fluid replenishment situation:
the monitoring device generates a corresponding operation instruction, generates and displays a time line in a trend graph and/or a waveform graph in response to the operation instruction, and displays the measured value of the central venous pressure and/or the physiological sign related to the fluid infusion condition at a time point corresponding to the time line.
It is understood that the operation of the user in the interface of the fluid replacement situation dedicated tool at least includes one of a gesture operation, a sliding operation, a clicking operation and a voice control operation, for example, when the user performs the clicking operation on the display, the monitoring device may receive the clicking operation, and at this time, the clicking operation generates an operation instruction, that is, the operation instruction may be defined in advance, for example, the measurement values of the time points corresponding to the display time line of the sliding operation (such as the left-sliding operation, the right-sliding operation, the up-sliding operation and the down-sliding operation, and the like) or the measurement values of the time points corresponding to the display time line of the clicking operation (such as the click trend graph and/or the waveform graph, the operation of the double click trend graph and/or the waveform graph, and the like) or the measurement values of the time points corresponding to the display time line of the gesture operation (such as swinging the wrist or the arm to, for example, the above is only an example and does not represent a limitation on the operation of the user in the interface of the tool dedicated for fluid infusion, such as a wrist or an arm is swung to the right, for example, a four-finger retracting operation or a three-finger sliding operation, etc.), or a voice control operation is defined as displaying a time line and a measured value of a time point corresponding to the time line (for example, a displayed sound is received, that is, the displayed time line and the measured value of the time point corresponding to the time line are displayed).
In summary, it can be seen that, in the embodiment of the present invention, the monitoring device can monitor the central venous pressure monitoring data of the monitored object in real time during the fluid infusion process of the monitored object, central venous pressure trend information is generated according to the central venous pressure monitoring data and is displayed on a special tool interface for fluid infusion, meanwhile, the fluid infusion baseline and the first identification line and/or the second identification line are displayed in the fluid infusion condition special tool interface, and sending prompt information according to the intersection relationship between the measured value of the central venous pressure of the monitored object at the current moment and the first identification line and/or the second identification line to assist doctors or nurses in supplementing liquid to the monitored object, the method is used for improving the problem that in the prior art, when a doctor carries out liquid treatment on a target object, the doctor needs to watch and record the parameter change of the central venous pressure of a patient and judge whether the liquid treatment needs to be stopped according to the parameter change.
