The Itamar WatchPAT One uses a finger sensor, pulse oximeter, movement detector, and a chest sensor to track data in seven areas related to sleep wellness:
- Abnormal respiratory events (obstructive and central)
- True sleep time
- Snoring and breathing patterns
- Oxygen saturation
- Heart rate
- Sleep stages
- Body position
The WatchPAT One home sleep test is exclusively designed to test for obstructive and central sleep apnea. As a result, we only recommend the test for people with moderate to severe symptoms of these disorders. People with a history of cardiorespiratory disease, stroke, insomnia, or hypoventilation should arrange for an overnight sleep study in a lab rather than take the at-home test.
