Watchpat - home sleep apnea testing made simple

Home Sleep Apnea Test

WatchPAT is an innovative FDA-cleared wrist mounted home sleep apnea test device for the diagnosis of Sleep Breathing Disorders (SBD), which allows testing in the comfort of the patient’s own home.

WatchPAT has been clinically validated against the "Gold Standard", polysomnography (PSG), with a documented correlation of up to 90% to PSG.1

The Watchpat home sleep apnea test is recommended by leading US cardiologists, including Dr. David Vorchheimer MD and Dr. Larry Chinitz MD, as a convenient home sleep monitor for sleep apnea diagnosis at home.

  • Simple and comfortable for outstanding patient compliance
  • Clinically reliable with less than 1% failure rate2
  • "Total Sleep Time™" for the most accurate AHI
  • Complete sleep architecture for a comprehensive diagnosis
  • Scalable cost effective solution for high volume workflow
  • Automatically generated report for fast diagnosis and treatment turnaround
  • zzzPATTM software with an advanced automatic algorithm for scoring of respiratory events
  • CloudPATTM cloud based IT solution for convenient sleep diagnosis and secure patient data transfers
  • Central + enable specific identification of Central Sleep Apnea (CSA)

Thanks to its innovative use of technology, WatchPAT™ offers unparalleled performance, reliability and satisfaction – for both patients and healthcare professionals:

The Easiest to Use Home Sleep Apnea test

WatchPAT is worn like a simple wrist-watch, with no need for belts, wires or nasal cannulas. The simple and intuitive use leads to outstanding compliance and minimal failure rate (< 1%).

Accurate & Comprehensive:

WatchPAT is the only (non-EEG) HST that measures “True Sleep Time” (rather than total recording time) and provides complete sleep architecture.

Advanced Proprietary Technology:

WatchPAT operates on Peripheral Arterial Tone (PAT) signal. PAT measures the arterial volume changes at the fingertip, reflecting the sympathetic nervous system activation.


WatchPAT requires minimal cleaning, preparation or handling before and after patient use and saves valuable staff time. Fully automated reports are generated within minutes, further increasing workflow efficiencies and treatment turnaround.

WatchPAT’s Clinical Parameters


Improving Patient Flow Management

zzzPAT Home Sleep Apnea Test Software

The zzzPAT is a proprietary PC or server-based analysis software used with the WatchPAT device.  The software’s advanced algorithm is automatic, eliminating the need for subjective manual scoring of respiratory events. If needed, the software also enables manual scoring for compliance with AASM standards.  A comprehensive sleep study report is generated within minutes after downloading the study data, allowing patients to initiate treatment without delay.

CloudPAT Home Sleep Apnea Test Platform

CloudPAT is a HIPAA-compliant web-based cloud application that allows users to streamline their workflow electronically, without having to operate or maintain an in-house solution.

CloudPAT provides instant access to comprehensive study reports from any online location, as well as the option of sending studies for interpretation by a certified sleep physician.
