The sleep apnea detection feature that Apple's most recent Apple Watch models offer has expanded to several more countries in Europe, Asia, South America, and more.Sleep apnea is a disorder where a person's breathing repeatedly stops and starts again during sleep, preventing rest.Sleep apnea detection on Apple Watch uses the device's accelerometer to monitor tiny movements at the wrist that are linked with interruptions in respiratory patterns.
Disturbances that occur multiple times over several nights can indicate sleep apnea.Sleep apnea detection and notifications have expanded to the following areas: Argentina Australia Christmas Island Cocos (Keeling) Islands Ecuador Heard and McDonald Islands Honduras Indonesia Moldova Norfolk Island Serbia Taiwan Thailand Ukraine Vietnam Sleep Apnea detection is available on the Apple Watch Series 9, Apple Watch Series 10, and Apple Watch Ultra 2 in more than 150 countries around the world.Apple Watch users have to wear the watch for several nights in a row to get an initial reading, though nightly Breathing Disturbances are listed in the Health app on iPhone.
In addition to bringing sleep apnea detection to more countries, Apple is also expanding AFib History, ECGs, and Irregular Heart Rhythm Notifications to a few more areas.ECG readings and Irregular Rhythm Notifications have launched in Argentina, Costa Rica, and Serbia, while AFib history is now available in Argentina and Serbia.AFib history is designed for people who have a diagnosis of atrial fibrillation from a physician.
