WatchPAT Home Sleep Test

Sleep Study with WatchPAT

WatchPAT is one of the most user-friendly systems currently available, extracting the physiological information required to determine the presence and severity of Obstructive Sleep Apnea (OSA) with just one sensor attached to the finger! 


WatchPAT enables simple and accurate OSA testing while avoiding the complexity and discomfort associated with traditional air-flow based systems. It is currently being used by the Sleep Lab in Singapore for ambulatory home sleep study.

"A nice marriage between technology with simplicity"

 - Dr. Kent Smith

WatchPAT is the only (non-EEG) Home Sleep Test that measures True Sleep Time! (rather than total recording time)

True Sleep Time

True Sleep Time decreases the risk of misdiagnosis in up to 20% of patients and is especially important for patients who tend to wake up numerous times during the night.
