Breathe easy: Apple Watch can read oxygen levels again
Briefly

Apple will provide a software update for recent US Apple Watch models to reinstate the blood oxygen measurement feature, originally removed due to patent infringement. Pulse oximetry helps assess health in individuals with heart and lung conditions but is for wellness rather than medical diagnostics. While the feature was deactivated in January 2024 following an ITC ruling, the update will allow blood oxygen measurements to be analyzed on the iPhone's Health app instead of on the watch itself.
Apple is reintroducing the blood oxygen measurement feature for select Apple Watch models in the US through a software update, despite previous regulatory challenges.
Pulse oximetry can provide valuable insights for individuals with health issues like heart and lung conditions. However, the Apple Watch functionality is intended for wellness rather than medical diagnostics.
Due to patent infringement issues, Apple had to remove the blood oxygen feature in January 2024 but is now providing a redesigned feature that's accessible via iOS and watchOS updates.
The updated feature will not display blood oxygen measurements directly on the Apple Watch but will instead require users to check the iPhone's Health app for results.
