Abstract

The invention discloses a method and system for determining the type of an apnea event. The method comprises the steps of acquiring the waveform of breathing movement of a patient, calculating the amplitude of the waveform formed during the apnea event of the patient, and determining the type of the apnea event according to the amplitude. Compared with the prior art, the type of the apnea event is determined according to the waveform of the breathing movement of the patient during apnea period of the patient, the effect of pressure oscillation signals on the patient is avoided, and the effect of resistance or air leakage in an air path on a determination result can be avoided. In addition, according to the method, the requirement for the performance of a draught fan is not high, the normal treatment of the patient cannot be affected, and the compliance of the patient can be improved; signals are stable, and the antijamming capability is high.

Description

technical field

[0001] The present invention relates to the technical field of medical devices, in particular to a method for determining the type of an apnea event, and also to a system for determining the type of an apnea event. Background technique

[0002] Sleep apnea-hypopnea syndrome refers to recurrent episodes of apnea more than 30 times per night during sleep or sleep apnea-hypopnea index (AHI, Apnea Hypopnea Index) β‰₯ 5 times / hour accompanied by clinical symptoms such as lethargy. An apnea event is a temporary cessation of breathing during sleep. Generally speaking, apnea events are respectively obstructive apnea events, central apnea events and mixed apnea events. Repeated sleep apnea during sleep can easily cause severe hypoxia in the brain and blood, resulting in hypoxemia, which can induce high blood pressure, cerebral heart disease, arrhythmia, myocardial infarction, angina pectoris, and induce diseases in multiple systems of the human body.
