Why WatchPAT ™ 

Diagnosing Sleep Apnea Has Never Been This Easy

WatchPAT ™ is an FDA-approved portable diagnostic device that uses the most innovative technology to ensure the accurate screening, detection, and the follow-up treatment of sleep apnea. Its ease of use is unparalleled in the marketplace and it is greatly complemented by the fact that WatchPAT ™ testing is done in the comfort of your patient’s own bedroom, an environment that best reflects the pattern of their sleep habits. That fact alone may prove to be a lifeline for the millions of undiagnosed patients who are unwilling to spend the night away from home in a hospital sleep center. And for those patients who are waiting for a polysomnography (PSG) but can’t be tested due to sleep center backlog, WatchPAT ™ offers an immediate solution. WatchPAT ™ has been validated against PSG.


Top 10 Medical Innovations for 2010

". . . devices are typically worn on the patient's wrist and use a non-invasive fingermounted probe to measure signals that indicate changes in the autonomic nervous system . . ."

 —Cleveland Clinic, December 2009

• Ease of use: Wrist-worn device

—Only three leads for patients to wear—no canullas, no cumbersome head straps

• Sleep study report in real time

—more time with the patient

• Actual sleep time and sleep state

• Access to raw data—enabling standard sleep expert PSG analysis and manual override if deemed professionally necessary. Raw data cannot be altered

• Lowest failure rate of all sleep apnea ambulatory devices

• The most precise, user-friendly ambulatory sleep apnea monitor available



Sleep Studies: WatchPAT ™ vs. PSG

Numerous validation studies demonstrated a high degree of correlation in RDI and AHI between WatchPAT ™ and PSG sleep studies. With WatchPAT ™, both RDI and AHI scores are highly reproducible, showing correlation between home and in-laboratory sleep studies. WatchPAT ™ has excellent reliability with minimal failure rate (approximately 1%) during data acquisition or data analysis, and requires minimal technician time compared to PSG. WatchPAT ™ monitors changes in peripheral arterial tone (PAT) and activity, as well as in blood oxygen saturation levels. It also identifies sleep apnea events just like the equipment used in PSG sleep studies performed in hospital sleep labs. WatchPAT ™ has been the subject of numerous clinical trials resulting in over 130 peer-reviewed papers and abstracts. Of these, 13 manuscripts validate WatchPAT ™ by comparing it head-to-head with PSG. In fact, more validation articles vs. PSG have been published in peer-reviewed journals about WatchPAT ™ than with any other portable sleep-testing device.
