WatchPAT ONE offers the same simplicity, accuracy and reliability as other WatchPAT products. The simple smartphone app transmits the WatchPAT ONE's data from 7 channels to the cloud.  As soon as the study is completed the clinician can review the automated study results.

Improved Workflow

  • Immediate access to sleep data and study results
  • Data interpretation anytime, anywhere with cloud based solution
  • Requires less back-office support


  • No return shipment
  • No cleaning, No downloading or charging
  • No infection risk

HSAT Program Growth

  • Ideal for patients outside service area
  • No capital investment required
  • Simple way to reduce periodic backlog
Prevent up to 20% Misdiagnosis with True Sleep Time¹

Prevent up to 20% Misdiagnosis with True Sleep Time¹

  • 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 time1
Improved Accuracy with Sleep Architecture

Improved Accuracy with Sleep Architecture

WatchPAT’s clinically validated Sleep Architecture
provides information on sleep staging including sleep efficiency, sleep latency and REM latency 2-3. 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

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.
