Problems solved by technology

[0003] Among the four basic modes, the pressure control mode is PCV mode and PRCV mode. The calculation of airway resistance and compliance is not accurate or changes during the working process of the ventilator, and the existing control mode takes a long time to adjust it. cycle to level off the pressure on the ventilator
For example, the target pressure value will fluctuate for a long time, which will cause the ventilator to confront the user (ie the patient), and in severe cases will endanger the life of the patient.

Abstract

The invention provides a respirator pressure control method and system. The method includes the following steps: aerating a respirator according to preset airway resistance and preset compliance so as to respectively measure multiple airway flow rates and multiple airway pressures, wherein the airway flow rates are in one-to-one correspondence to the airway pressures; calculating airway resistance and airway compliance of each aeration according to each airway flow rate and each airway pressure; calculating average airway resistance and average airway compliance of the respirator according to the multiple airway resistances and the multiple airway compliances acquired for each aeration; controlling flow rate of aeration according to the average airway resistance and average airway compliance so as to control pressure of the respirator. According to the method, the flow rate of aeration is controlled according to the average airway resistance and the average compliance of the respirator so as to control the pressure of the respirator, so that regulation time is shortened, and performance of the respirator is improved.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to a pressure control method of a ventilator. Background technique [0002] The commonly used basic control modes of ventilators mainly include VCV mode, PCV mode, PRVC mode and PSV mode, while other breathing modes are composed of these four basic modes. [0003] Among the four basic modes, the pressure control mode is PCV mode and PRCV mode. The calculation of airway resistance and compliance is inaccurate or changes during the working process of the ventilator, and the existing control mode takes a long time to adjust it. cycle to level off the pressure on the ventilator. For example, the target pressure value will fluctuate for a long time, which will cause the ventilator to confront the user (ie, the patient), and in severe cases, the life of the patient will be endangered. Contents of the invention [0004] The object of the present invention is to solve at least one o...
