To measure blood oxygen on your Apple Watch, open the Blood Oxygen app and tap start.
Blood oxygen measurements, or SpO2 levels, represent what percentage of oxygen you have in your blood. Since we depend on oxygen to function, this measurement can be an important indicator of our overall health. Higher SpO2 levels are a good thing. A normal reading is anything between 95% and 99%. Low levels of blood oxygen, meanwhile, can lead to dangerous symptoms known as hypoxemia.
Blood oxygen monitoring is available on the Apple Watch Series 6, Series 7, Series 8, and Ultra. Make sure your device is running the latest watchOS to take advantage of this useful feature. According to Apple, this tool is designed for users aged 18 and older.
When you set up your device for the first time, the Blood Oxygen app should be installed in the Health app. If needed, you can reinstall the app from the App Store on your Apple Watch.
Your Apple Watch will occasionally measure your blood oxygen levels when you are not moving if background measurements are on. The device will only take blood oxygen measurements overnight if you are tracking sleep with your Apple Watch. You can disable these measurements if the sensor’s light disrupts your sleep.
Compatible Apple Watches also allow you to take blood oxygen measurements on demand. For an accurate reading, make sure your band is snug and that the back of your Apple Watch is touching your skin. Your watch should rest an inch or two above your wrist bone.
You can find all your blood oxygen data in the Health app on your paired iPhone.
If you would like your blood oxygen data to appear in the Summary tab, scroll down and tap Add to Favorites.
