Home Sleep Study

Itamar WatchPAT 

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.

Prevent up to 20% Misdiagnosis with True Sleep Time³

  • WatchPAT calculates AHI and RDI using the patient’s True Sleep Time rather than the recorded time used in most commercially available HSAT’s
  • True Sleep Time reduces the risk of misdiagnosis and misclassification that has been reported up to 20% with using total recording time

Improved Accuracy with Sleep Architecture

WatchPAT’s clinically validated Sleep Architecture
provides information on sleep staging including sleep efficiency, sleep latency and REM latency4-5. It also provides the added value of detecting REM related sleep apnea with REM and non-REM AHI.

High Accuracy with Central Sleep Apnea Identification

WatchPAT has been clinically proven to detect all types of apnea events. The Central PLUS Module enables specific identification of Central Sleep Apnea (CSA) and Percent of Sleep Time with Cheyne-Stokes Respiration.
