Judging method of sleep apnea mode of patient

Abstract

The invention discloses a judging method of a sleep apnea mode of a patient. The judging method includes the steps of S1, preparing a BiPAP (bi-level positive airway pressure) Plus; S2, providing a referential tidal volume V for the patient through the BiPAP Plus; S3, setting a critical pressure valve value X equal to 0.1-0.2; S4, starting the BiPAP Plus to provided assisted respiration to the patient; S5, calculating the difference value DeltaVn of the referential tidal volume V and the actual breathing tidal volume Vn of the patient in the n cycle, and calculating the ratio Xn of the DeltaVn and the referential tidal volume V; S6, comparing Xn with X, in the case that Xn is not smaller than X, providing the additional bi-level positive airway pressure ventilation to the patient; S7, recording a real-time breathing tidal volume Vn+1 of the patient in the n+1 cycle, when the real-time breathing volume Vn+1 in the n+1 cycle of the patient gradually becomes larger, judging that the patient is in the blocking type sleep apnea; when the real-time breathing volume Vn+1 in the n+1 cycle of the patient is no changed, judging that the patient is in central sleep apnea. The judging method is suitable for people of all ages and high in practicability.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a method for detecting and judging the tidal volume of a bilevel ventilator. Background technique [0002] Ventilator, as the name suggests, is a device that can replace, control or change people's normal physiological breathing, increase lung ventilation, improve respiratory function, reduce breathing work consumption, and save heart reserve capacity. Its main application has three aspects, one is to save the patient when the patient's life is dying, shortness of breath, etc.; the other is to help the patient to recuperate and restore his normal breathing; the other is for the general population to sleep People with respiratory diseases such as snoring and other causes of narrowed airway; [0003] Traditional ventilators generally include two breathing modes, namely S mode and T mode. S mode represents the trigger control mode, and T mode represents the time control m...

Problems solved by technology

[0005] However, the corresponding method for discriminating the patient's sleep apnea mode in the above-mentioned prior art is cumbersome and requires complex software calculations to realize, making the corresponding cost relatively high. Therefore, based on the defects of the prior art, a method is designed. It is very necessary to have a simple method for distinguishing the sleep apnea pattern of patients so that the cost can be greatly reduced.
