Embodiment Construction

[0055] A specific embodiment applying the present invention:

[0056] 1. Functional requirements and parameter values

[0057] 1) Sampling and AD conversion of the output signal of the body surface respiratory muscle electromyography measurement circuit, for example: precision 12bit, sampling frequency 4K / s.

[0058] 2) The signal is processed by fourth-order low-pass filtering (for example: cut-off frequency of 600Hz) and power frequency notch (50Hz and 60Hz optional).

[0059] 3) High-pass filtering filters out polarization voltage, artifacts and unstable components, for example: the cut-off frequency is 10 Hz.

[0060] 4) Calculate the EMG envelope and form the respiratory EMG signal.

[0061] 2. Filtering, envelope calculation and respiratory EMG signal generation algorithm

[0062] 2.1, fourth-order low-pass filtering and power frequency notch

[0063] For low-pass filtering and power frequency notch, the pulse transfer function is:

[0064] G ( z ) = a 0 + a ...

Abstract

The invention discloses a method and device for treating central sleep apnea. The method includes the following steps that 1, surface electromyogram signals of respiratory muscles are collected; 2, filtering is carried out; 3, enveloping calculation of the surface electromyogram signals is carried out; 4, respiratory electromyogram sign signals are generated; 5, the oxyhemoglobin saturation of a patient is detected, wherein an oxyhemoglobin saturation probe clamped to a finger can be used; 6, if no respiratory electromyogram sign signal is collected in continuous 10 seconds and the decrease rate of oxyhemoglobin saturation exceeds 3%, external pacing is carried out on respiratory muscles. The method is applied to the device. The method and the device are precise, effective and good in use effect.

Description

【Technical Field】 [0001] The present invention relates to the field of medical technology, in particular to a method and device for treating central sleep apnea. 【Background technique】 [0002] Central sleep apnea (CSA) is characterized by repeated interruptions in airflow caused by impaired central drive function during sleep. Central apnea refers to apnea time ≥ 10 seconds, no breathing exercise. Usually this situation is considered abnormal if it is more than 5 times per hour. CSA syndrome refers to an average of more than 5 central apneas per hour during sleep, and symptoms related to sleep fragments (frequent awakenings) and / or excessive daytime sleepiness. Central apnea can also occur in patients with obstructive apnea. Therefore, we should focus on the identification of CSA. Although there is no absolute standard on this issue, studies of CSA patients usually require 50% or even more than 80% of the symptoms to be central. CSA is usually not induced by a single factor, ...
