Project name:

Itamar medical WatchPat™

Project description:

The WatchPat device uses peripheral arterial tonometry in conjunction with pulse oximetry and actigraphy to assess for respiratory disturbances. It indirectly detects apnea and hypopnea via selectively measuring peripheral arterial volume changes (mediated by α-adrenergic receptors of vascular smooth muscle) using a finger-mounted plethysmograph. The information is collated with pulse oximetry (detection of oxygen desaturation) in conjunction with heart rate and is further analyzed using a predeveloped automated algorithm.
