摘要：
Systems and methods for detecting a general breathing event and for anticipating an onset of an obstructive sleep apnea (OSA) event. The method for detecting a general breathing event includes receiving a plurality of signals from at least one microphone (401). The method also includes determining a one-sided power spectral density from the received signals (408). The method further includes distinguishing each received signal as either a breath signal or a background noise signal (415). The method still further includes calculating a breath signature by processing each breath signal (420).
