Method for the exploration of obstructive sleep apnea based on the oxygen saturation signal (Machine-translation by Google Translate, not legally binding)
We present a method for the exploration of obstructive sleep apnea based on the oxygen saturation signal. With this method, an exploration or screening system is proposed that reduces the need to perform other more complex diagnostic tests such as polysomnography. These methods may be of interest to manufacturers of diagnostic devices and be applied in ambulatory settings. The method comprises a segmentation of the oxygen saturation signal, a process of extraction of variables in the time domain and frequency based on the variance of the signal and calculation of power in certain frequency bands. We propose a classification system based on logistic regression for the determination of the presence or absence of apnea in each segment of 1 minute. Fig. No. 1 presents the flow diagram of the method. (Machine-translation by Google Translate, not legally binding)
