WatchPAT Home Sleep Apnea Test (HSAT) is a sleep apnea diagnostic aid that utilizes the peripheral arterial tonometry signal to enable simple, accurate, and reliable testing while avoiding the complexity and discomfort associated with traditional air-flow based systems.
Simple
3 points of contact
Intuitive design with improved patient comfort
Improved workflow with rapid download time and one-step processing
Accurate
7 Channels with 4 respiratory indices
89% correlation to PSG in AHI1
WatchPAT uses the patient’s total sleep time rather than the recorded time, which reduces the risk of underdiagnosis.
Reliable
~98% success rate.
Approved measure in the 2017 AASM HSAT Clinical Practice Guidelines
Scalable cost effective solutions
Central Plus Module
Central Sleep Apnea (CSA) identification
Percentage of Cheyne-Stokes Respiration

Accurate Auto Scoring
Reduces the Risk of Underdiagnosis
WatchPAT calculates AHI and RDI using the patient’s Total Sleep Time rather than the recorded time used in most commercially available HSAT’s
Total sleep time reduces the risk of underdiagnosis and misclassification that has been reported up to 20% with using total recording time3.
Sleep Architecture
WatchPAT’s validated sleep staging, which detects wake, light sleep, deep sleep, and REM, provides information on sleep architecture. It also provides the added value of detecting REM related sleep apnea with REM and non-REM AHI.
The Central+ sensor enables identification of central sleep apnea
WatchPAT is an aid to diagnose sleep apnea including obstructive and central sleep apnea. The Central PLUS Module enables specific identification of Central Sleep Apnea (CSA) and Percent of Sleep Time with Cheyne-Stokes Respiration.
