WatchPAT – Simple Sleep Health Management

WatchPAT is an FDA-approved portable diagnostic device that uniquely uses finger based physiology and innovative technology to enable simple and accurate Obstructive Sleep Apnea (OSA) testing while avoiding the complexity and discomfort associated with traditional air-flow based systems.

The Easiest to Use Home Sleep Test:

WatchPAT is worn like a simple wrist-watch, with no need for belts, wires or nasal cannulas. The simple and intuitive use leads to outstanding compliance and minimal failure rate (< 1%).

The Most Clinically Validated Home Sleep Test:

WatchPAT was extensively validated against in-lab PSG (“the gold standard”), with a documented correlation of 90%.

Accurate & Comprehensive:

WatchPAT is the only (non-EEG) HST that measures “True Sleep Time” (rather than total recording time) and provides complete sleep architecture.

Advanced Proprietary Technology:

WatchPAT operates on Peripheral Arterial Tone (PAT) signal. PAT measures the arterial volume changes at the fingertip, reflecting the sympathetic nervous system activation.


WatchPAT requires minimal cleaning, preparation or handling before and after patient use and saves valuable staff time. Fully automated reports are generated within minutes, further increasing workflow efficiencies and treatment turnaround.
