Embodiment Construction

[0022] The present invention will be further described now in conjunction with accompanying drawing.

[0023] The method for distinguishing obstructive sleep apnea and central sleep apnea of ​​the present invention is implemented in combination with a ventilator. The ventilator should include at least: a flow generator for providing pressurized gas; a mask for sealingly engaging the patient's face and delivering pressurized gas to the patient's airway in use; an air delivery tube for for connecting the flow generator with the mask; a sensor for measuring the respiratory flow and pressure signals near the flow generator; a controller for receiving the measured respiratory flow and pressure signals and controlling the flow generator operation and control of gas transmission. Most of the ventilators currently on the market can meet the above hardware requirements.

[0024] The applicant is in view of the pathological difference between obstructive sleep apnea and central sleep ...

Abstract

The invention relates to a method for distinguishing obstructive sleep apnea and central sleep apnea. The method comprises the steps that a breathing machine outputs a trapezoidal wave; the airway flow in the airway of a patient is collected, and thus the change condition of the airway flow within a period of time after the trapezoidal wave is output is obtained, wherein the change condition of the airway flow comprises the air flow rate; the airway resistance is calculated based on the amplitude of the trapezoidal wave and the air flow rate; whether the patient suffers from obstructive sleepapnea or central sleep apnea is judged according to the airway resistance. The method provided by the invention has the advantages that the distinguishing is accurate, and the realization is simple.

Description

technical field [0001] The invention relates to the field of ventilators, in particular to a method for distinguishing obstructive sleep apnea and central sleep apnea. Background technique [0002] Sleep apnea-hypopnea syndrome refers to recurrent episodes of apnea more than 30 times during 7 hours of sleep per night or sleep apnea-hypopnea index (Apnea / Hypopnea Index, usually referred to as AHI) ≥ 5 times / hour accompanied by A sleep-breathing disorder with clinical symptoms such as lethargy. [0003] Sleep apnea is usually divided into obstructive sleep apnea (Obstructive Sleep Apnea, usually referred to as OSA), central sleep apnea (Central Sleep Apnea, usually referred to as CSA) and mixed sleep apnea (Mixed Sleep Apnea, usually referred to as For MSA) three types. Among them, OSA refers to the upper airway obstruction caused by the relaxation of the soft tissues near the throat, and the narrowing of the airway leads to apnea during sleep. CSA means that the respirator...
