Abstract
A computer-based detection method employable with a sleeping subject for aiding in the differential-character diagnosis and treatments of apneic events includes gathering heart-sound data, including S1 data and S2 data. A combined time-frequency-intensity (TFI) analysis, of the gathered data is performed, in a continuous manner, over a selected time period. Based on the performing and the performed TFI analysis, an output is produced which is indicative of the presence and character of any detected apneic event.
