WatchPat Home Sleep Testing FAQs
What is WatchPAT?
WatchPAT is an FDA-approved state-of-the-art technology portable sleep study device created for use in the comfort of your home to ensure accurate screening, detection, and correct follow-up treatment of sleep apnea. The WatchPAT is portable and easy to use at home. It monitors your blood oxygen saturation levels and detects changes in peripheral arterial tone.
What is Peripheral Arterial Tone (PAT)?
Peripheral Arterial tone (PAT) is a physiological signal that mirrors changes in the autonomic nervous system caused by respiratory disturbances during sleep. The automatic algorithm of WatchPAT analyzes the PAT signal amplitude along with heart rate and oxygen saturation to identify respiratory events. Using specific signal patterns, the algorithm provides the two critical indices called the AHI and the RDI.
PAT technology is a non-invasive window to the cardiovascular system and autonomic nervous system. The PAT Signal is measured from the fingertip by recording finger arterial pulsatile volume changes.
How long does the WatchPAT home study take?
The amount of time people sleep varies from person to person. The WatchPAT is put on when you go to bed. It is taken off when you wake in the morning. The WatchPAT will record your particular sleep cycles.
Is the WatchPat Sleep Study Covered by Medical Insurance?
Currently, coverage varies from insurance carrier to carrier. At-home sleep studies with WatchPAT are typically covered by most insurance carriers. Even so, some insurance policies specifically exclude coverage for the diagnosis and/or treatment of sleep disorders. Patients need to contact their local carrier regarding their specific policy plan.
