Validation of the Peripheral Arterial Tone to Detect Sleep-disordered Breathing in Patients With Chronic Heart Failure

The WatchPAT 200 (TM) is a wrist worn diagnostic device for detecting SDB. Its main part is the measurement of the peripheral arterial tone (PAT) via a plethysmographic based finger-mounted probe. It can measure the level of sympathetic activation of the autonomic nervous system. Pulse rate, oxygen saturation and snoring/body position levels are calculated, too. A software program (zzzPAT (TM)) with a special algorithm analyzes the raw data and creates a sleep report. Therefore the property of the WatchPAT 200 (TM) proclaims that the WatchPAT 200 (TM) can detect sleep events and SDB.

"The PSG is known as the Gold Standard for detecting SDB: experienced sleep physicians and technicians score events (apnea/hypopnea) using current AASM Guidelines."
