Method for adjusting positive pressure of breathing machine airway

Abstract

The invention provides a method for adjusting positive pressure of a breathing machine airway. The method comprises a step S01 of adopting respiratory signals during users'breathing; a step S02 of extracting breathing index characteristic signals; a step S03 of adjusting the airway positive pressure of a breathing machine at an expiration stage; a step S04 of collecting adjusted user respiratory signals; a step S05 of judging whether adjusted breathing index characteristics deteriorate, performing contrastive analysis on the adjusted breathing index characteristic signals in the step S04 and breathing index characteristic signals in the step S02, and if the breathing index characteristics have no deterioration, skipping to the step S03; and if the breathing index characteristics deteriorate, stopping increasing the lower probing degree of the airway positive pressure of the breathing machine at the expiration stage. According to the adjusting method, the airway positive pressure of the breathing machine at the expiration stage can be automatically adjusted to an appropriate value, so that users expire more smoothly, and users'use comfort degree is improved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a method for regulating the positive airway pressure of a ventilator. Background technique [0002] At present, when non-invasive ventilation is used to treat COPD (chronic obstructive pulmonary disease, chronic obstructive pulmonary disease), it mainly relies on non-invasive ventilator to provide sufficient pressure support to ensure that patients receive sufficient ventilation. One of the key points of non-invasive ventilation intervention in COPD treatment is Ensure that the patient gets enough ventilation, and the ventilation requirement varies from person to person, and during the entire treatment process, due to the influence of the patient's physical condition and environment, the required pressure support is not necessarily constant. Rather, a degree of adjustment is required at any time. Traditional ventilators only provide the set expiratory positive airway pressure E...

AI Technical Summary

Problems solved by technology

Traditional ventilators only provide the set expiratory positive airway pressure EPAP (expiratory positive airway pressure) and inspiratory positive airway pressure IPAP (inspiratory positive airway pressure) during treatment. Therefore, the ventilator is still provided when the user exhales. Positive pressure EPAP, although the EPAP value is generally not high, but because it is blown out from the ventilator, it is still a major resistance for the user when exhaling
