A New Era of Home Sleep Apnea Testing.

Watch Full Video

WatchPAT®️ is an innovative Home Sleep Apnea Device (HSAT) that utilizes the peripheral arterial signal (PAT®️) for Sleep Apnea diagnosis.  It measures up to 7 channels (PAT®️ 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 all types of apnea events. WatchPAT®️ provides AHI, AHIc, RDI, and ODI based upon True Sleep Time and Sleep Staging. The WatchPAT®️ Home Sleep Test (HST) is clinically validated with an 89% correlation to PSG1. The PAT signal was included in the 2017 AASM Clinical Practice Guidelines as technically adequate.
