WatchPAT Home Sleep Apnea Test (HSAT) is a sleep apnea diagnostic aid that utilizes the peripheral arterial tonometry signal.  It measures up to 7 channels peripheral arterial tonometry signal, heart rate, oximetry, actigraphy, body position, snoring, and chest motion via three points of contact. Within one minute post-study, the raw data is downloaded and auto-scored identifying sleep apnea events. WatchPAT home sleep apnea test provides AHI, AHIc, RDI, and ODI based upon Total Sleep Time and Sleep Staging. The WatchPAT is clinically validated with an 89% correlation to PSG in AHI1. The peripheral arterial tonometry signal was included in the 2017 AASM Clinical Practice Guidelines as technically adequate.
