Abstract

Systems and methods provide for detecting snoring, and for determining the presence of sleep disordered breathing using detected snoring. Snoring indicative signals generated by one or more patient-internal or external sensors are detected. The presence of sleep disordered breathing is algorithmically determined, patient-internally or externally, using the snoring signals. Algorithmically determining presence of sleep disordered breathing may include computing a snoring index developed from the detected snoring. Sleep apnea may be detected using the snoring index. Sleep apnea may be verified using internal or external sensors. A positive airway pressure device may operate cooperatively to verify and treat sleep disordered breathing.
