Blood Oxygen Monitoring Returns to Recent US Apple Watches with Software Updates

ByMike Moffit

With the release of iOS 18.6.1 and watchOS 11.6.1, Apple restored blood oxygen monitoring capabilities to US Apple Watch Series 9, Series 10, and Ultra 2 models that previously had this feature disabled due to a patent infringement suit by medical device maker Masimo. Apple’s redesign processes blood oxygen data on the paired iPhone rather than on the watch itself. After updating both devices, you can view your blood oxygen readings in the Health app under Browse > Respiratory > Blood Oxygen. If blood oxygen monitoring doesn’t activate immediately after updating, try opening the ECG app on your watch to trigger the necessary software asset download. Apple Watch units that predate the ban and those sold in other countries continue to work as they always have, with the Blood Oxygen app on the watch itself.

Social Media: Apple restored blood oxygen monitoring on recent US Apple Watch models through a creative workaround that processes and displays data on the iPhone instead of the watch. Here’s how to get it working again.

    I am off to Daytona for the 75th Bike Week. We went out to the 75th anniversary of the Sturgis Bike Week so it is only appropriate for us to hit the one sort of in our neighborhood, too. We will be riding on our 2003 Victory motorcycles and trying to avoid any big roads.

    Sugaring season in Vermont is well underway and this time of the year in Vermont always reminds me when we used to sugar the old-fashioned way. Now it is mostly pipelines and big sugaring operations but back when we lived in North Wolcott, Vermont I had a big work horse. The horse was kind of untrained but hitching her to the sled with the big heavy sap gathering tank made her behave. We would tap the trees by hand, hang buckets and as the sap began to flow we would tramp through the deep snow to empty the buckets into the tank. One horsepower was a lot of power as the horse would make her way through the sugar maples and the tank got full. We would take it to our makeshift sugaring arch and boil the sap into yummy syrup. Some of the best times! I still prefer the “grade b” syrup over fancy grade.
