A New Era In Home Sleep Testing

Watch Full Video

WatchPAT™ is an innovative diagnostic Home Sleep Apnea Test (HSAT) that utilizes the peripheral arterial signal (PAT™).  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. WatchPAT is clinically validated with an 89% correlation to PSG1.  The PAT signal was included in the 2017 AASM Clinical Practice Guidelines as technically adequate.
