Method for evaluating capacity reactivity and monitoring system

Abstract

The invention provides a method for evaluating capacity reactivity and a monitoring system, the method is applied to the monitoring system in communication connection with breathing equipment, and the method comprises the following steps: acquiring the breathing equipment through the monitoring system, and providing a first value of a vital sign parameter of a subject during ventilation to the subject by initial setting, the initial setting is ventilation setting adopted by the breathing equipment before a ventilation test is carried out on the object; the monitoring system controls test setting of the breathing equipment according to a preset program, a second numerical value of vital sign parameters of the object when the breathing equipment provides ventilation for the object according to the test setting is obtained, and the test setting is ventilation setting adopted when the breathing equipment conducts a ventilation test on the object; a variation of the vital sign parameter is determined by the monitoring system based on the first value and the second value, the variation being used to assess the capacity reactivity of the subject. According to the method, manual parameter recording and evaluation result calculation are not needed, and the workload of users is reduced.

Description

technical field [0001] The present invention generally relates to the technical field of medical equipment, and more particularly relates to a method and monitoring system for assessing volume responsiveness. Background technique [0002] Clinically, for mechanically ventilated patients, there is a lack of intuitive and easy-to-use volume responsiveness assessment tools to guide fluid resuscitation. The doctor needs to manually record the pulse pressure variation (PPV), stroke volume variation (SVV) parameters, cardiac output, heart rate, end-tidal carbon dioxide, mean arterial pressure and other parameters of the monitor, and then adjust the positive end-expiratory pressure of the ventilator Ventilation (Peep) or tidal volume parameters, or end-tidal blocking settings, and last for 30 seconds to 1 minute, and then manually record the PPV, SVV, cardiac output, heart rate, end-tidal carbon dioxide, mean arterial Pressure and other parameters, and finally calculate the change...

AI Technical Summary

Problems solved by technology

[0004] 1. The doctor needs to manually record the PPV or SVV parameters twice, and calculate the evaluation results, which increases the workload;

[0005] 2. It is necessary to change the parameter settings of the ventilator twice. After the evaluation, it is easy to forget to restore the ventilator settings, causing clinical risks;

[0006] 3. Volume responsiveness assessment results cannot be automatically stored and recorded, which is inconvenient for subsequent analysis and review of patients
