  • 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
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.
