WatchPAT Home Sleep Apnea Device

The innovative, proprietary Peripheral Arterial Tone (PAT®) signal is a noninvasive measure of the arterial pulsatile volume changes at the patient’s fingertip

The PAT® signal attenuation and accelerated pulse rate has been shown to reflect sympathetic activation, which is a clinically validated surrogate for autonomic arousals and micro-arousals found in sleep disordered breathing (SDB)¹

Combined with oximetry desaturations or resaturations, the proprietary WatchPAT® algorithm accurately classifies the SDB events into AHI, RDI, and ODI to provide physicians with a comprehensive assessment

Clinically validated sleep architecture provides information on sleep staging, including sleep efficiency, sleep latency, and rapid eye movement (REM) latency

The WatchPAT is FDA-cleared to identify AFib events that occur during sleep, accurately proven in a multi-centre study.

This helps to flag at risk patients that help the physician decide if further arrhythmic investigation is indicated.  

Significant 89% correlation with PSG for AHI, as reported in a 14-study meta-analysis (P <0.001) on simultaneous simultaneous PAT ®and PSG recording.
