[0049] In order to fully understand the present application, a detailed structure will be provided in the following description to illustrate the technical solution proposed by the present application. The optional embodiments of the present application are described in detail below. However, in addition to these detailed descriptions, the present application may also have other implementation methods.

[0050] Below, a method for displaying blood circulation status according to an embodiment of the present application will be described with reference to the accompanying drawings. First, reference is made to FIG1 , which is a schematic flow chart of a method 100 for displaying blood circulation status according to an embodiment of the present application. As shown in FIG1 , the method 100 for displaying blood circulation status according to an embodiment of the present application includes the following steps:

[0051] In step S110, at least two blood circulation status assessment indicators related to the monitored subject are determined, wherein the at least two blood circulation status assessment indicators include at least two of a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator, wherein the volume responsiveness assessment indicator is used to reflect the response of the volume status to circulatory therapy, the blood pressure responsiveness assessment indicator is used to reflect the response of the blood pressure status to circulatory therapy, and the perfusion responsiveness assessment indicator is used to reflect the response of the tissue perfusion status to circulatory therapy;

[0052] In step S120, a correspondence between each of the blood circulation status assessment indicators and cardiovascular parameters is obtained, wherein the volume responsiveness assessment indicator corresponds to at least one first cardiovascular parameter, the blood pressure responsiveness assessment indicator corresponds to at least one second cardiovascular parameter, and the perfusion responsiveness assessment indicator corresponds to at least one third cardiovascular parameter;

[0053] In step S130, based on the corresponding relationship, monitoring data of cardiovascular parameters corresponding to the at least two blood circulation status evaluation indicators are acquired;

[0054] In step S140, a blood circulation status diagram is generated based on the monitoring data of the cardiovascular parameters corresponding to the at least two blood circulation status assessment indicators, wherein the blood circulation status diagram includes at least two display units, each of the display units being used to represent one of the blood circulation status assessment indicators and the monitoring data of the cardiovascular parameters corresponding to the blood circulation status assessment indicator;

[0055] In step S150, the blood circulation status icon is displayed in the blood circulation status display area of ​​the display interface.

[0056] The method 100 for displaying blood circulation status in an embodiment of the present application displays at least two blood circulation status assessment indicators of the volume responsiveness assessment indicator, the blood pressure responsiveness assessment indicator, and the perfusion responsiveness assessment indicator and their corresponding monitoring data of cardiovascular parameters through a blood circulation status diagram, which can more comprehensively reflect the blood circulation status and guide medical staff in performing circulatory treatment.

[0057] For example, the method 100 for displaying blood circulation status according to an embodiment of the present application can be implemented in a monitoring device, such as a blood monitor. The blood circulation status display area can be displayed on the monitor's display. Besides monitors, the method 100 for displaying blood circulation status according to an embodiment of the present application can also be implemented in a central station, a cloud service system, or other monitoring devices.

[0058] In step S110, at least two blood circulation status assessment indicators related to the monitored subject are determined. The at least two blood circulation status assessment indicators include at least two of a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator. For example, the at least two blood circulation status assessment indicators may include a volume responsiveness assessment indicator and a blood pressure responsiveness assessment indicator, a blood pressure responsiveness assessment indicator and a perfusion responsiveness assessment indicator, or a volume responsiveness assessment indicator and a perfusion responsiveness assessment indicator; or the at least two blood circulation status assessment indicators may include a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator, thereby more comprehensively assessing the monitored subject's blood circulation status.

[0059] Among them, the volume responsiveness assessment index reflects the response of volume status to circulatory therapy, namely, whether the patient's volume status improves when circulatory therapy is implemented. Circulatory therapy primarily includes fluid therapy and drug therapy. Fluid therapy includes fluid administration and diuretics, while drug therapy includes the administration of vasoactive and cardiotonic drugs. Improved volume status ensures adequate circulating blood volume, which is essential for maintaining stable circulatory status. The blood pressure responsiveness assessment index reflects the response of blood pressure status to circulatory therapy, namely, whether the patient's blood pressure improves when circulatory therapy is implemented. Even with adequate circulating blood volume, the heart still needs sufficient pumping capacity to supply blood to various tissues and organs. Without good blood pressure responsiveness, blindly providing fluid resuscitation will only increase the cardiac burden. The perfusion responsiveness assessment index reflects the response of tissue perfusion status to circulatory therapy, namely, whether the patient's perfusion status improves when circulatory therapy is implemented. Perfusion status refers to whether the tissue or trachea is receiving an adequate blood supply to maintain tissue or organ function. Insufficient tissue perfusion can lead to a series of ischemic or hypoxic lesions, and in severe cases, can cause organ dysfunction or failure. If perfusion status cannot be improved, even if volume and blood pressure status are restored, hypoperfusion may occur, and even long-term hypoperfusion can lead to serious consequences such as multiple organ dysfunction syndrome.

[0060] Therefore, the embodiment of the present application adopts at least two of the volume responsiveness evaluation index, the blood pressure responsiveness evaluation index and the perfusion responsiveness evaluation index as the evaluation index of the blood circulation state. Compared with most of the current monitoring devices that only evaluate volume responsiveness, it can more comprehensively present the blood circulation state of the monitored object and guide clinical circulatory treatment. The selection of the blood circulation state evaluation index can be fixed, or automatically performed by the monitoring device according to the state of the monitored object or the state of the device itself, or manually performed by the user. For example, when manual selection is adopted, a setting interface for the blood circulation state evaluation index can be provided to the user, and a selection operation for the blood circulation state evaluation index can be obtained through the setting interface. According to the obtained selection operation, at least two blood circulation state evaluation indicators are selected from the volume responsiveness evaluation index, the blood pressure responsiveness evaluation index and the perfusion responsiveness evaluation index.

[0061] The volume responsiveness assessment index, blood pressure responsiveness assessment index, and perfusion responsiveness assessment index can be predictive indices, i.e., before administering circulatory therapy to the monitored subject, they can predict whether the monitored subject's volume status, blood pressure status, and perfusion status can be improved under circulatory therapy. The volume responsiveness assessment index, blood pressure responsiveness assessment index, and perfusion responsiveness assessment index can also be evaluative indices, i.e., during the administration of circulatory therapy to the monitored subject, they can evaluate whether the monitored subject's volume status, blood pressure status, and perfusion status have improved under circulatory therapy.

[0062] In step S120, a correspondence between each blood circulation status assessment indicator and a cardiovascular parameter is obtained. The volume responsiveness assessment indicator corresponds to at least one first cardiovascular parameter, the blood pressure responsiveness assessment indicator corresponds to at least one second cardiovascular parameter, and the perfusion responsiveness assessment indicator corresponds to at least one third cardiovascular parameter. The first, second, and third cardiovascular parameters can be cardiovascular parameters monitored by the monitoring device itself, or they can be cardiovascular parameters monitored by other medical devices (e.g., a ventilator, etc.) that have established a communication connection with the monitoring device.

[0063] Exemplarily, the first cardiovascular parameter includes at least one of stroke volume variability (SVV) and pulse pressure variability (PPV). Stroke volume variability is a natural phenomenon that occurs all the time, and stroke volume variability represents the ratio of the difference between the highest stroke volume and the lowest stroke volume to the average stroke volume. Pulse pressure variability is the ratio of the difference between the maximum and minimum arterial blood pressure to the average of these two values. Stroke volume variability and pulse pressure variability can predict the body's responsiveness to circulatory therapy, that is, whether cardiac output can be increased through circulatory therapy. Based on the above reasons, at least one of SVV and PPV can be selected as the first cardiovascular parameter related to the volume responsiveness assessment index.

[0064] Exemplarily, the second cardiovascular parameter includes at least one of dynamic arterial elasticity (Eadyn) and systemic vascular resistance (SVR). Dynamic arterial elasticity is the ratio of pulse pressure variability (PPV) to stroke volume variability (SVV). Eadyn can be used to guide medical staff in hemodynamic management. If the monitored subject's Eadyn is high, then an increase in cardiac output will lead to an increase in arterial blood pressure. If Eadyn is low, even if the monitored subject is volume responsive, increasing cardiac output will not effectively increase blood pressure proportionally. For such monitored subjects, consideration should be given to adding pressor drugs to correct hypotension. SVR refers to the blood flow resistance in the systemic circulation, that is, the resistance encountered by blood when flowing through blood vessels. SVR can, to a certain extent, reflect the vasoconstriction state of human blood vessels and is the main factor affecting human blood pressure. Any change in vascular resistance caused by any reason may cause a change in blood pressure. Based on the above reasons, at least one of Eadyn and SVR can be selected as a second cardiovascular parameter related to the blood pressure responsiveness assessment indicator.

[0065] Exemplarily, the third cardiovascular parameter includes at least one of the perfusion index (PI), the capillary refill time (CRT) and the arteriovenous blood gas ratio (GAP-ratio). PI can reflect the blood flow in the limb arteries and thus reflect the blood perfusion capacity. CRT refers to the time required for the capillaries to refill after the withdrawal of compression. If this time is less than a certain threshold, it proves that the local tissue microcirculation is normal, otherwise it indicates the presence of peripheral circulation disorders. GAP-ratio is the venous-arterial carbon dioxide partial pressure difference, which is inversely proportional to the flow rate and directly proportional to the amount of carbon dioxide produced. Therefore, for microcirculation, the smaller the GAP, the higher the microcirculatory blood flow. Based on the above reasons, at least one of PI, CRT and GAP-ratio can be selected as the third cardiovascular parameter related to the perfusion responsiveness evaluation index.

[0066] It should be noted that the above cardiovascular parameters are only used as examples. In addition to the above cardiovascular parameters, the volume responsiveness assessment index, the blood pressure responsiveness assessment index and the perfusion responsiveness assessment index may also correspond to other cardiovascular parameters related to volume responsiveness, blood pressure responsiveness and perfusion responsiveness. The correspondence between each blood circulation status assessment index and the cardiovascular parameter may be pre-configured in the monitoring device. The cardiovascular parameters corresponding to different blood circulation status assessment indicators may be fixed, or a number of optional cardiovascular parameters may be provided for each blood circulation status assessment indicator, and the cardiovascular parameters corresponding to each blood circulation status assessment indicator may be determined based on the user's selection operation of the cardiovascular parameter.

[0067] In step S130, based on the correspondence between each blood circulation status assessment indicator and the cardiovascular parameter, monitoring data of the cardiovascular parameters corresponding to at least two blood circulation status assessment indicators are obtained. If the cardiovascular parameters are those monitored by the monitoring device itself, the monitoring data of the cardiovascular parameters can be obtained via the monitoring unit of the monitoring device. If the cardiovascular parameters are those monitored by other medical devices, the monitoring data of the cardiovascular parameters collected by the other medical devices can be obtained via a communication connection between the monitoring device and the other medical devices.

[0068] In step S140, a blood circulation status diagram is generated based on the monitoring data of the cardiovascular parameters corresponding to at least two blood circulation status evaluation indicators. The blood circulation status diagram includes at least two display units, each display unit being used to represent a blood circulation status evaluation indicator and the monitoring data of the cardiovascular parameters corresponding to the blood circulation status evaluation indicator. Through the blood circulation status diagram, the blood circulation status of the monitored object can be presented to the user clearly and intuitively. Each display unit can represent both the corresponding blood circulation status evaluation indicator and the monitoring data of the cardiovascular parameters corresponding to the blood circulation status evaluation indicator. This can avoid the situation where medical staff do not understand the blood circulation status evaluation indicators related to the parameters when only the monitoring data of the cardiovascular parameters are displayed, thereby lowering the threshold for use and being more user-friendly, especially for medical staff who lack relevant experience.

[0069] Exemplarily, when one of the blood circulation status assessment indicators corresponds to a cardiovascular parameter, a display unit corresponding to the blood circulation status assessment indicator is generated based on the cardiovascular parameter corresponding to the blood circulation status assessment indicator. For example, if the first cardiovascular parameter corresponding to the volume responsiveness assessment indicator includes only stroke volume variability, a display unit corresponding to the volume responsiveness assessment indicator is generated based on the monitoring data of the stroke volume variability.

[0070] When one of the blood circulation status assessment indicators corresponds to at least two cardiovascular parameters, a calculation result is obtained based on the at least two cardiovascular parameters corresponding to the blood circulation status assessment indicator, and a display unit corresponding to the blood circulation status assessment indicator is generated based on the calculation result. Continuing with the example of the volume responsiveness assessment indicator, if the first cardiovascular parameter corresponding to the volume responsiveness assessment indicator includes stroke volume variability and pulse pressure variability, a weighted summation of the monitoring data of the stroke volume variability and the monitoring data of the pulse pressure variability can be performed based on their respective weights, and a display unit corresponding to the volume responsiveness assessment indicator can be generated based on the result of the weighted summation.

[0071] In one embodiment, the blood circulation status diagram includes three indicator bars arranged in a triangular shape around a common center point. Each indicator bar is used to represent a blood circulation status assessment indicator and its corresponding cardiovascular parameter monitoring data. The three indicator bars correspond to a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator, respectively. The type of blood circulation status assessment indicator corresponding to each indicator bar is labeled near each indicator bar. The three indicator bars of the blood circulation status diagram may also be arranged in other ways, such as in parallel. Furthermore, the shape of the indicator bars may be rectangular or any other shape.

[0072] Each indicator bar of the blood circulation status diagram can represent the monitoring data of the cardiovascular parameter corresponding to the blood circulation status assessment index indicated by the indicator bar by a preset color. For example, the background color of the indicator bar is gray, and the proportion of the indicator bar filled with other colors represents the size of the monitoring data of the corresponding cardiovascular parameter. The indicator bars corresponding to different blood circulation status assessment indicators can be displayed in different colors; or the indicator bars corresponding to different blood circulation status assessment indicators can be displayed in the same color, and the size of the monitoring data of the cardiovascular parameter can be represented by different colors. For example, when the monitoring data is less than or equal to the preset threshold, the indicator bar is displayed in green, and when the monitoring data is greater than the preset threshold, the indicator bar is displayed in red.

[0073] Furthermore, the area surrounding each indicator bar in the blood circulation status graphic may display the value of the cardiovascular parameter monitoring data corresponding to that indicator bar. In some embodiments, each indicator bar also displays a mark representing the threshold value of the cardiovascular parameter corresponding to that indicator bar, so that the user can determine whether the monitoring data of the cardiovascular parameter corresponding to the indicator bar is within a normal threshold range.

[0074] It should be noted that the triangular arrangement of indicator bars described above is only one example of a blood circulation status diagram; other forms of blood circulation status diagrams are possible. For example, the blood circulation status diagram can be implemented as a circle composed of three sectors, with each sector forming a display unit corresponding to a blood circulation status assessment indicator. The specific form of the display unit is not limited in this embodiment of the present application.

[0075] In one embodiment, a comprehensive evaluation result of the blood circulation status of the monitored subject can also be obtained based on the monitoring data of the cardiovascular parameters corresponding to at least two blood circulation status evaluation indicators. The comprehensive evaluation result can more concisely and clearly reflect the blood circulation status of the monitored subject. The blood circulation status diagram can also be used to display the comprehensive evaluation result. Specifically, the blood circulation status diagram also includes a comprehensive display graphic for representing the comprehensive evaluation result. Exemplarily, the comprehensive display graphic can be a graphic formed by connecting the position points representing the monitoring data of the cardiovascular parameters in each display unit.

[0076] The comprehensive assessment result may be a deterioration risk score for the monitored subject's circulatory status. The higher the deterioration risk score, the greater the risk of deterioration in the monitored subject's circulatory status. Displaying the deterioration risk score helps medical staff take timely treatment measures when the risk of deterioration is high. In addition to presenting the comprehensive assessment results through a comprehensive graphical display, the total assessment result may also be displayed in text near the circulatory status graphic. For example, the numerical value of the deterioration risk score may be displayed near the circulatory status graphic.

[0077] For example, when the risk score for worsening blood circulation status is higher than a preset score, the comprehensive display graphic used to display the worsening risk score can be highlighted to alert medical staff. The highlighting method includes but is not limited to highlighting, flashing, changing color, etc.

[0078] For example, when the comprehensive assessment result is a risk score for worsening the blood circulation status of the monitored subject, the individual scores corresponding to each blood circulation status assessment indicator can be obtained based on the monitoring data of the cardiovascular parameters corresponding to the blood circulation status assessment indicator, and the individual scores corresponding to at least two blood circulation status assessment indicators can be weighted and summed to obtain the risk score for worsening the blood circulation status of the monitored subject. A correspondence table between the monitoring data of the cardiovascular parameters corresponding to each blood circulation status assessment indicator and the individual scores can be obtained, and the individual scores corresponding to each blood circulation status assessment indicator can be determined based on the correspondence table. The correspondence table contains individual scores corresponding to multiple threshold ranges, and the individual scores corresponding to the blood circulation status assessment indicators can be obtained based on the threshold range within which the monitoring data of the cardiovascular parameters fall.

[0079] When performing the weighted summation, the weights corresponding to different blood circulation status assessment indicators can be the same, that is, the individual scores corresponding to at least two blood circulation status assessment indicators are directly summed to obtain the overall deterioration risk score. Alternatively, the weights corresponding to different blood circulation status assessment indicators can be different, and the weight corresponding to each blood circulation status assessment indicator can be a fixed weight or a user-set weight.

[0080] In addition, in some embodiments, monitoring data of cardiovascular parameters corresponding to at least two blood circulation status evaluation indicators can be input into a trained blood circulation status evaluation model to obtain the comprehensive evaluation result output by the blood circulation status evaluation model.

[0081] In some embodiments, a blood circulation status display area can be displayed in a monitoring interface. The monitoring interface is used to display conventional vital sign parameters of the target object. Specifically, the information displayed on the monitoring interface includes real-time values ​​of the vital sign parameters of the monitored object, real-time waveforms of the vital sign parameters of the monitored object, personal information of the monitored object, and various operation control icons. Specifically, an operation control icon representing a blood circulation status assessment can be displayed on the monitoring interface. When a selection operation is received for the operation control icon, the blood circulation status display area is displayed in response to the received selection operation. That is, in a conventional monitoring interface, the user can select an operation control icon representing a blood circulation status assessment to display the blood circulation status display area as described above in the monitoring interface. The blood circulation status display area can be a window that pops up in the monitoring interface, or an area divided in the monitoring interface. The blood circulation status display area can also constitute a complete display interface.

[0082] In summary, the method 100 for displaying the blood circulation status of an embodiment of the present application displays at least two blood circulation status evaluation indicators and monitoring data of cardiovascular parameters corresponding to each blood circulation status evaluation indicator through a blood circulation status diagram, which can more comprehensively present the blood circulation status of the monitored object and guide circulatory treatment.

[0083] Another embodiment of the present application provides a method for displaying blood circulation status. As shown in FIG2 , the method 200 for displaying blood circulation status according to another embodiment of the present application includes the following steps:

[0084] In step S210, at least two blood circulation status assessment indicators related to the monitored subject are determined, wherein the at least two blood circulation status assessment indicators include at least two of a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator, wherein the volume responsiveness assessment indicator is used to reflect the response of the volume status to the circulatory therapy, the blood pressure responsiveness assessment indicator is used to reflect the response of the blood pressure status to the circulatory therapy, and the perfusion responsiveness assessment indicator is used to reflect the response of the tissue perfusion status to the circulatory therapy;

[0085] In step S220, a correspondence between each of the blood circulation status assessment indicators and cardiovascular parameters is obtained, wherein the volume responsiveness assessment indicator corresponds to at least one first cardiovascular parameter, the blood pressure responsiveness assessment indicator corresponds to at least one second cardiovascular parameter, and the perfusion responsiveness assessment indicator corresponds to at least one third cardiovascular parameter;

[0086] In step S230, based on the corresponding relationship, monitoring data of cardiovascular parameters corresponding to the at least two blood circulation status evaluation indicators are acquired;

[0087] In step S240, monitoring data of cardiovascular parameters corresponding to the at least two blood circulation status assessment indicators are displayed in the blood circulation status display area of ​​the display interface; wherein, when the monitoring data of the first cardiovascular parameter is displayed, it is prompted that the first cardiovascular parameter is related to volume responsiveness; when the monitoring data of the second cardiovascular parameter is displayed, it is prompted that the second cardiovascular parameter is related to blood pressure responsiveness; and when the monitoring data of the third cardiovascular parameter is displayed, it is prompted that the third cardiovascular parameter is related to perfusion responsiveness.

[0088] The method 200 for displaying blood circulation status in the embodiment of the present application is similar to the method 100 for displaying blood circulation status described above, and also displays blood circulation status based on at least two of the volume responsiveness assessment index, the blood pressure responsiveness assessment index, and the perfusion responsiveness assessment index. The difference is that the method 200 for displaying blood circulation status in the embodiment of the present application employs a display method that, while displaying the monitoring data of the cardiovascular parameter corresponding to each blood circulation status assessment index, also displays the blood circulation status assessment index associated with that cardiovascular parameter, allowing the user to understand the different dimensions of blood circulation status reflected by different cardiovascular parameters while viewing the monitoring data of the cardiovascular parameters.

[0089] If only the monitoring data of multiple cardiovascular parameters is displayed without indicating the corresponding relationship between the cardiovascular parameters and blood circulation status assessment indicators, medical staff may not understand the blood circulation status related to the cardiovascular parameters, making the display of cardiovascular parameters ineffective. In contrast, the embodiment of the present invention not only displays cardiovascular parameters related to at least two blood circulation statuses in a comprehensive manner, but also indicates the blood circulation status related to the cardiovascular parameters while displaying the monitoring data of the cardiovascular parameters, thus lowering the threshold for use and being more user-friendly, especially for medical staff who lack relevant experience.

[0090] For example, the blood circulation status display area can be divided into at least two sub-areas, and each sub-area displays the blood circulation status evaluation index corresponding to the sub-area and the monitoring data of the cardiovascular parameters corresponding to the blood circulation status evaluation index. Alternatively, the blood circulation status evaluation index corresponding to each cardiovascular parameter can be marked while displaying the monitoring data of the cardiovascular parameters. Alternatively, the monitoring data of the cardiovascular parameters corresponding to different blood circulation status evaluation indicators can be displayed in different colors, and the user can be prompted with the blood circulation status evaluation index corresponding to each color. The embodiments of the present application do not limit the specific method of displaying the correspondence between cardiovascular parameters and blood circulation status evaluation indicators.

[0091] Exemplarily, the first cardiovascular parameter corresponding to the volume responsiveness assessment index includes at least one of stroke volume variability and pulse pressure variability. The second cardiovascular parameter corresponding to the blood pressure responsiveness assessment index includes at least one of dynamic arterial elasticity and systemic vascular resistance. The third cardiovascular parameter corresponding to the perfusion responsiveness assessment index includes at least one of perfusion index, capillary self-filling time, and arteriovenous blood gas ratio. The cardiovascular parameters corresponding to different blood circulation status assessment indicators can be fixed, or a number of optional cardiovascular parameters can be provided for each blood circulation status assessment indicator, and the cardiovascular parameters corresponding to each blood circulation status assessment indicator are determined based on the user's selection operation of the cardiovascular parameters.

[0092] Furthermore, in the blood circulation status display area of ​​the display interface, a change trend graph of the monitoring data of the cardiovascular parameters corresponding to at least two blood circulation status evaluation indicators within a preset time range can also be displayed simultaneously. The preset time range can be fixed, or the preset time range can be set according to the setting operation received from the user. The monitoring data of each cardiovascular parameter and its corresponding change trend graph can be displayed adjacent to each other, for example, the monitoring data of each cardiovascular parameter can be displayed on the left or right side of its change trend graph. The change trend graph can be displayed in the blood circulation status display area together with the monitoring data by default; alternatively, the change trend graph of the cardiovascular parameter can be displayed when a selection operation for the monitoring data of the cardiovascular parameter is received.

[0093] In some embodiments, a comprehensive assessment result of the subject's circulatory status can be obtained based on the monitoring data of the cardiovascular parameters corresponding to the at least two circulatory status assessment indicators, and the comprehensive assessment result can be displayed in the circulatory status display area. For example, the comprehensive assessment result is a risk score for deterioration of the subject's circulatory status.

[0094] When the comprehensive assessment result is a risk score for worsening the subject's circulatory status, the individual scores corresponding to each circulatory status assessment indicator can be obtained based on the monitoring data of the cardiovascular parameters corresponding to each circulatory status assessment indicator. The individual scores corresponding to the at least two circulatory status assessment indicators can then be weighted and summed to obtain the risk score for worsening the subject's circulatory status. Alternatively, the monitoring data of the cardiovascular parameters corresponding to the at least two circulatory status assessment indicators can be input into a trained circulatory status assessment model to obtain the comprehensive assessment result output by the circulatory status assessment model.

[0095] In summary, the method 200 for displaying the blood circulation status of the embodiment of the present application not only displays the monitoring data of cardiovascular parameters but also presents the correspondence between different cardiovascular parameters and volume responsiveness evaluation indicators, blood pressure responsiveness evaluation indicators, and perfusion responsiveness evaluation indicators, thereby being able to more comprehensively present the blood circulation status of the monitored subject and guide circulatory treatment.

[0096] Another aspect of the present invention provides a method for displaying blood circulation status. As shown in FIG3 , the method 300 for displaying blood circulation status according to one embodiment of the present invention includes the following steps:

[0097] In step S310, at least two blood circulation status assessment indicators related to the monitored subject are determined, wherein the at least two blood circulation status assessment indicators include at least two of a volume responsiveness assessment indicator, a blood pressure responsiveness assessment indicator, and a perfusion responsiveness assessment indicator, wherein the volume responsiveness assessment indicator is used to reflect the response of the volume status to the circulatory therapy, the blood pressure responsiveness assessment indicator is used to reflect the response of the blood pressure status to the circulatory therapy, and the perfusion responsiveness assessment indicator is used to reflect the response of the tissue perfusion status to the circulatory therapy;

[0098] In step S320, a correspondence between each of the blood circulation status assessment indicators and cardiovascular parameters is obtained, wherein the volume responsiveness assessment indicator corresponds to at least one first cardiovascular parameter, the blood pressure responsiveness assessment indicator corresponds to at least one second cardiovascular parameter, and the perfusion responsiveness assessment indicator corresponds to at least one third cardiovascular parameter;

[0099] In step S330, based on the corresponding relationship, monitoring data of cardiovascular parameters corresponding to the at least two blood circulation status evaluation indicators are acquired;

[0100] In step S340, a comprehensive evaluation result of the blood circulation state of the monitored subject is obtained based on the monitoring data of the cardiovascular parameters corresponding to the at least two blood circulation state evaluation indicators;

[0101] In step S350, the comprehensive evaluation result is displayed in the blood circulation status display area of ​​the display interface.

[0102] The method 300 for displaying the blood circulation status of the embodiment of the present application obtains a comprehensive evaluation result of the blood circulation status of the monitored subject based on the monitoring data of the cardiovascular parameters corresponding to at least two indicators among the volume responsiveness evaluation index, the blood pressure responsiveness evaluation index and the perfusion responsiveness evaluation index. It can intuitively and clearly prompt medical staff to the current blood circulation status of the monitored subject and guide medical staff to perform circulatory treatment.

[0103] Exemplarily, the first cardiovascular parameter corresponding to the volume responsiveness assessment index includes at least one of stroke volume variability and pulse pressure variability. The second cardiovascular parameter corresponding to the blood pressure responsiveness assessment index includes at least one of dynamic arterial elasticity and systemic vascular resistance. The third cardiovascular parameter corresponding to the perfusion responsiveness assessment index includes at least one of perfusion index, capillary self-filling time, and arteriovenous blood gas ratio. The cardiovascular parameters corresponding to different blood circulation status assessment indicators can be fixed, or a number of optional cardiovascular parameters can be provided for each blood circulation status assessment indicator, and the cardiovascular parameters corresponding to each blood circulation status assessment indicator are determined based on the user's selection operation of the cardiovascular parameters.

[0104] For example, the comprehensive assessment result of the subject's circulatory status is a deterioration risk score for the subject's circulatory status. The higher the deterioration risk score, the greater the likelihood of deterioration in the subject's circulatory status. Displaying the deterioration risk score enables medical staff to take timely treatment measures when the risk of deterioration is high. For example, when the deterioration risk score for the circulatory status exceeds a preset score, an alarm message can be generated to alert medical staff. The alarm message can include an alarm sound, an alarm indicator light, an alarm icon displayed on a display interface, and the like.

[0105] Exemplarily, when the comprehensive assessment result is a risk score for worsening the blood circulation status of the monitored subject, the individual score corresponding to each blood circulation status assessment indicator can be obtained based on the monitoring data of the cardiovascular parameters corresponding to the blood circulation status assessment indicator; the individual scores corresponding to at least two blood circulation status assessment indicators are weighted and summed to obtain the risk score for worsening the blood circulation status of the monitored subject. A correspondence table between the monitoring data of the cardiovascular parameters corresponding to each blood circulation status assessment indicator and the individual scores can be obtained, and the individual score corresponding to each blood circulation status assessment indicator can be determined based on the correspondence table. The correspondence table contains individual scores corresponding to multiple threshold ranges, and the individual scores corresponding to the blood circulation status assessment indicator can be obtained based on the threshold range within which the monitoring data of the cardiovascular parameters fall.

[0106] In another embodiment, the monitoring data of cardiovascular parameters corresponding to at least two blood circulation status assessment indicators can be input into a trained blood circulation status assessment model to obtain a comprehensive assessment result output by the blood circulation status assessment model. The training samples of the blood circulation status assessment model can be the monitoring data of cardiovascular parameters corresponding to at least two blood circulation status assessment indicators of multiple patients and their corresponding blood circulation status. The comprehensive assessment result output by the blood circulation status assessment model can be a quantitative comprehensive assessment result, for example, it can be a risk score for deterioration of the blood circulation status. Alternatively, the comprehensive assessment result output by the blood circulation status assessment model can be a qualitative comprehensive assessment result, for example, it can be a good blood circulation status or a poor blood circulation status, a high risk of deterioration or a low risk of deterioration, etc.

[0107] For example, in addition to displaying the comprehensive assessment results of the blood circulation status, the blood circulation status display area may also display monitoring data of cardiovascular parameters corresponding to at least two blood circulation status assessment indicators, so that the user can understand the monitored subject's volume responsiveness, blood pressure responsiveness, and perfusion responsiveness. Furthermore, a trend chart of the monitoring data of the cardiovascular parameters corresponding to the at least two blood circulation status assessment indicators may also be displayed in the blood circulation status display area.

[0108] In summary, the method 300 for displaying the blood circulation status of the embodiment of the present application obtains a comprehensive evaluation result of the blood circulation status of the monitored object based on the monitoring data of the cardiovascular parameters corresponding to at least two cardiovascular parameter evaluation indicators. The comprehensive evaluation result can more accurately reflect the blood circulation status of the monitored object and guide circulatory treatment.

[0109] Another aspect of the present invention provides a method for displaying blood circulation status. As shown in FIG4 , the method 400 for displaying blood circulation status according to one embodiment of the present invention includes the following steps:

[0111] In step S420, a correspondence between each of the blood circulation status assessment indicators and cardiovascular parameters is obtained, wherein the volume responsiveness assessment indicator corresponds to at least one first cardiovascular parameter, the blood pressure responsiveness assessment indicator corresponds to at least one second cardiovascular parameter, and the perfusion responsiveness assessment indicator corresponds to at least one third cardiovascular parameter;

[0112] In step S430, based on the corresponding relationship, monitoring data of cardiovascular parameters corresponding to the at least two blood circulation status evaluation indicators are acquired;
