Embodiment 1

[0021] Such as figure 1 As shown, the initial screening method for sleep apnea hypopnea syndrome with low physiological load includes the following steps:

[0022] First, the blood oxygen pulse fingertip is used to collect the fingertip pulse blood oxygen signal of the human body in sleep state, and the blood oxygen pulse finger clip obtains the pulse signal by analyzing the blood oxygen signal; then, from the collected pulse wave signal, digital filter Techniques, such as low-pass filter and band-pass filter, detect the heart rate and respiration rate through the PPG signal to obtain the ECG signal.

Abstract

The invention relates to a preliminary screening method for sleep apnea hypopnea syndrome with low physiological load. Using ECG and respiratory signals extracted from pulse waves and using data processing and classification algorithm, ECG signal were analyzed in frequency domain to obtain heart rate variability index for cardiac function evaluation, and then combine HRV with respiratory signals,sleep staging and event discrimination of obstructive sleep apnea syndrome were performed with machine learning trained classifier, the invention reduces the types of signals needed to be detected byfurther mining the information related to sleep contained in the signals, and can carry out sleep analysis and cardiac function evaluation only by collecting blood oxygen pulse signals, thereby achieving the purpose of reducing physiological and psychological load of a subject and more convenient and accurate measurement.

Description

technical field [0001] The present invention relates to the medical field, and more specifically, relates to a method for preliminary screening of sleep apnea hypopnea syndrome with low physiological load. Background technique [0002] Sleep detection technology is the most basic means to study sleep medicine. The previous sleep detection technology was mainly based on polysomnography technology. Although this technology can detect sleep quality and some sleep disorders, it must stick many electrodes and sensors on the subject. The number is often more than 15, and requires professionals to operate, and there is no reflection of cardiac function in the analysis data, which will constitute a considerable physiological and psychological load for many people, limiting the wider application of PSG technology. Contents of the invention [0003] In order to solve the shortcomings of the large number of detection devices in the prior art and the need for professional personnel t...
