Sleep state staging method and device based on cardiopulmonary coupling and computer readable storage medium

Abstract

The invention relates to a sleep state staging method and a device based on cardiopulmonary coupling and a computer readable storage medium, and relates to the field of sleep monitoring. The method comprises the steps of obtaining an initial heart rate signal and an initial respiration signal based on a piezoelectric induction signal; respectively filtering and smoothing the initial heart rate signal and the initial breathing signal to obtain a heart rate waveform signal and a breathing waveform signal; performing waveform time domain conversion on the heart rate waveform signal and the breathing waveform signal to obtain a time domain heart rate signal and a time domain breathing signal; acquiring a time-domain heart rate signal and a time-domain breathing signal of the detection period, performing Fourier transform, and calculating to obtain a frequency-domain heart rate signal and a frequency-domain breathing signal; acquiring heart rate features from the frequency-domain heart rate signal, and acquiring breathing features from the frequency-domain breathing signal; based on a cardiopulmonary coupling algorithm, calculating cardiopulmonary coupling features through the heart rate features and the breathing features; and outputting judged sleep state stages according to the cardiopulmonary coupling features. The method and the device provided by the invention have the effect of monitoring the individual sleep state by stages.

Description

technical field [0001] The present application relates to the field of sleep monitoring, in particular to a sleep state staging based on cardiopulmonary coupling, a device and a computer-readable storage medium. Background technique [0002] Sleep is one of the most important physiological activities for people. The quality of sleep directly or indirectly affects the healthy development of the human body. Due to fast-paced life, stress and bad living habits, more people suffer from sleep disorders. Therefore, it is very important to monitor and evaluate sleep. [0003] At present, sleep state staging monitoring and staging is a more commonly used method, which is to extract the features in the EEG signal, and use the features in the EEG signal to determine the sleep state staging. However, the collection of EEG requires relatively sophisticated instruments and complicated calculation methods, which are not conducive to daily sleep detection. [0004] In view of the above-m...
