Apple’s ‘redesigned’ blood oxygen monitoring feature hits Apple Watches in the US today
More than a year after an import ban forced the company to remove blood oxygen monitoring from some US Apple Watch models, Apple says it will introduce a redesigned version of the feature later today. In a post on its newsroom website, the company said the feature will roll out to Apple Watch Series 9, Series 10, and Watch Ultra 2 users through a joint Apple Watch and iPhone update. Once Apple begins rolling out the software, you’ll need to update your devices to iOS 18.6.1 and watchOS 11.6.1 to access the reworked feature. Following the update, any blood oxygen data captured by your Apple Watch will be calculated on your iPhone, with the resulting data viewable in the respiratory section of the Health app.
“There will be no impact to Apple Watch units previously purchased that include the original Blood Oxygen feature, nor to Apple Watch units purchased outside of the US,” Apple said.
Today’s update marks another unexpected development in Apple’s long, drawn out legal feud with Masimo. In 2021, the medical device maker sued Apple, alleging the tech giant had infringed on its intellectual properties related to pulse oximeter blood-oxygen monitoring technology. Following a couple of years of legal back and forth, the issue came to a head when the US International Trade Commission (ITC) upheld a prior ruling that found Apple had violated Masimo’s patents. After former President Biden chose not to veto the decision, Apple was forced to temporarily pause sales of the Apple Watch Series 9 and Ultra 2. The company later started selling the wearables following an update the removed the infringing blood oxygen monitoring feature.
