# Apple Watch Sleep Apnea Notifications

FDA-authorized feature on supported Apple Watch models that flags possible signs of moderate to severe sleep apnea.

On supported Apple Watch models, the sleep apnea notification feature uses the accelerometer to measure Breathing Disturbances during sleep and can alert you to signs of possible moderate to severe sleep apnea over a 30-day period. It is not a diagnosis; a notification is a reason to ask a clinician about a sleep study.
