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.
True Sleep Time
True Sleep Time reduces the risk of misdiagnosis and misclassification that has been reported up to 20% with using total recording time2
Sleep Architecture
WatchPAT’s clinically validated Sleep Architecture provides information on sleep staging including sleep efficiency, sleep latency and REM latency 3-4
Central Sleep Apnea
The Central PLUS Module enables specific identification of Central Sleep Apnea (CSA) and Percent of Sleep Time with Cheyne-Stokes Respiration
Accurate Auto Scoring
Comprehensive report is created in less than a minute
Seven Channels
PAT, HR, Pulse-oximetry, Actigraphy, Body Position, Snoring, Chest Motion
