This paper presents a methodology to automatically screen for sleep apnea based on the detection of apnea and hypopnea events in the blood oxygen saturation (SpO ) signal. It starts by detecting all desaturations in the SpO signal. From these desaturations, a total of 143 time-domain features are ex...
