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.
