Signal processing method and computer equipment

Abstract

The invention provides a signal processing method and computer equipment, and relates to the technical field of signals, wherein the method comprises the following steps of obtaining an original bloodoxygen signal; preprocessing the original blood oxygen signal to obtain a first blood oxygen signal; determining a first time domain feature of the first blood oxygen signal, wherein the first time domain feature is used for indicating whether the blood oxygen saturation degree of the first blood oxygen signal decreases or not; and inputting the first time domain feature into a preset breathing classification model to obtain an affiliated target breathing type of the original blood oxygen signal. According to the embodiment of the invention, the signal processing equipment can perform classification according to the time domain feature capable of indicating whether the blood oxygen saturation degree of the first blood oxygen signal decreases or not in the first blood oxygen signal throughthe preset breathing classification model, so that the affiliated breathing type of the original blood oxygen signal corresponding to the first blood oxygen signal is determined. Compared with a threshold value discrimination method based on the apnea times and the apnea-hypopnea times, the signal processing method has the advantage that the accuracy for judging the breathing type is improved.

Description

technical field [0001] The invention relates to the field of signal technology, in particular to a signal processing method and computer equipment. Background technique [0002] In recent years, with the continuous development of signal technology, the application fields of signal technology have become more and more extensive. For example, in the medical field, medical signal data such as blood oxygen signals and ECG signals can be processed, and the obtained processing results can assist clinical analysis. [0003] At present, people pay more and more attention to the quality of sleep, so the problems in sleep have gradually begun to be paid attention to by people. Apnea (apnea) refers to the complete cessation of mouth and nose airflow for more than 10 seconds during sleep, hypopnea (hypopnea) refers to the amplitude of respiratory airflow is reduced by more than 50% compared with the baseline level, and the blood oxygen saturation is 4% lower than the baseline level at ...
