The WatchPAT™ One is an FDA and DOT-approved portable sleep apnea diagnostic device. Its innovative technology ensures the accurate screening, detection, and follow-up treatment of sleep apnea.


Traditional testing for sleep apnea includes performing a sleep study at a clinic. For many patients, sleep studies can be unproductive because of the unfamiliar environment, leading to conflicting results. There are a variety of at-home sleep studies that can be performed so that you can achieve accurate results that take into account your everyday sleep habits, behaviors, and possible factors.

WatchPAT is done in the comfort of your home, the environment that best reflects your natural sleep patterns, and is completed in one night of sleep. The portable monitoring device fits like a wristwatch and no nasal tube or uncomfortable body strap is required. You simply sleep for a single night wearing the comfortable wrist and finger attachments that monitor your true sleep time, sleep architecture, and sleep apnea.

WatchPAT accurately measures obstructive and central sleep apnea based on up to seven different factors:

  • PAT signal (peripheral arterial tone)
  • Heart rate
  • Oximetry (blood oxygen level)
  • Actigraphy (gross motor activity)
  • Body position
  • Snoring
  • Chest motion

These findings will be automatically sent to Dr. Wilk for review and discussion of the next steps in your treatment. During a follow-up, you’ll explore your sleep apnea solutions so you can enjoy a restful sleep.
