Watchpat 300

WatchPAT™ 300

WatchPAT™ 300 is an innovative diagnostic Home Sleep Apnea Test (HSAT) that utilizes the proprietary Peripheral Arterial Tone signal (PAT™) to enable simple, accurate and reliable sleep apnea testing while avoiding the complexity and discomfort associated with traditional air-flow based systems.

  • 3 points of contact
  • Intuitive design with improved patient comfort
  • Improved workflow with rapid download time and one-step processing
  • 7 Channels with 4 respiratory indices
  • 89% Correlation to PSG1  
  • Accurate diagnosis with true sleep time and sleep staging
  • 98% study 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


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 |Home Sleep Apnea Test ( HSAT)
  • True Sleep Time reduces the risk of misdiagnosis and misclassification that has been reported up to 20% with using total recording time3

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.
