HIGHLIGHTS

Prevent up to 20% Misdiagnosis with Total Sleep Time³

  • 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 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.
