What is WatchPAT?

WatchPAT is an FDA-approved portable diagnostic device that uses the most innovative technology to ensure the accurate screening, detection, and follow-up of sleep apnea. Its ease of use is unparalleled in the marketplace and it is greatly complemented by the fact that WatchPAT testing is done in the comfort of your own bedroom; an environment that best reflects the pattern of your sleep habits.

How to operate the WatchPAT?

The amount of time people sleep varies from person to person. The WatchPAT is put on when you go to bed and runs ten (10) consecutive hours after turned on. You should take it off (without the need to be turned off) when you wake up in the morning and return it to the clinic for sleep data downloading.
Thanks to WatchPAT’s automated data analysis, you don’t have to wait to get your diagnosis. Once you return the WatchPAT to your physician, you will receive an immediate detailed sleep report. This instantaneous report generation—compared to a lengthy wait in most hospital-based settings—allows you to initiate sleep apnea treatment the same day and without delay.

WatchPAT’s Unique Clinical Features

  • Real Sleep Time—measures actual time asleep—not just time in bed, like other home devices, providing a more accurate assessment of sleep apnea.
  • RDI and AHI—special indices that determine the severity of sleep apnea.
  • ODI (Oxygen Desaturation Index)—measurement of blood oxygen levels. When not enough oxygen reaches the brain, a person awakens from sleep.
  • Heart Rate—the number of heart beats per minute while sleeping.
  • Body Position—notes whether you sleep on your back (supine), front (prone) or side, all which influence apnea.
  • Snoring Intensity (dB)—loud snoring is a major indicator of sleep apnea.
  • Sleep Stages and Architecture (wake/light/deep)—the cyclical pattern of various NREM and REM sleep stages summarized in a chart called a hypnogram.
  • REM/NREM Sleep—dreaming sleep characterized by rapid eye movement (REM), the shortest portion of the sleep cycle; Non-REM (NREM) sleep, the largest portion of the sleep cycle, has three separate stages and distinct electrical brainwave patterns.
  • Sleep Fragmentation—repeated short interruptions of sleep throughout the night, reducing the total amount of time spent in the deepest level of sleep.
  • Sleep Statistics

WatchPAT Measures 6 Channels

  • PAT—Peripheral Arterial Tone, which is a physiological signal that mirrors changes in the autonomic nervous system caused by respiratory disturbances during sleep.
  • Oximetry—the measurement of oxygen levelsin the blood.
  • Actigraphy—the measurement of body movement while sleeping.
  • Heart Rate—the number of heart beats per minute while sleeping.
  • Body Position—notes whether you sleep on your back (supine), front (prone) or side, all which influence apnea.
  • Snoring Intensity (dB)—loud snoring is a major indicator of sleep apnea.
