A new health monitoring feature may be coming to the Apple Watch, allowing the smartwatch to keep an eye on your blood oxygen levels. This is in accordance with information found by 9to5Mac in exclusive snippets of code for the upcoming iOS 14 software update. Blood oxygen monitoring is mentioned in the code, and the wording seems to suggest that it will notify you if your oxygen saturation in the blood falls below a recommended amount. A healthy blood oxygen saturation level would be between 95 and 100%, while those with results below 90% should see a doctor. This can be a good way for those who wouldn't normally be able to take a test like this to keep an eye on these stats in the same way that an ECG (electrocardiogram) was introduced to the Apple Watch. 4) Per the iOS 14 code, Apple is also looking to provide a software or hardware fix to resolve an issue where the ECG feature doesn't always take the correct reading for those whose heart rate is between 100 and 120 beats per minute. What's unclear about the blood oxygen monitoring feature is whether or not you can use it on an existing Apple Watch. This may be something Apple can activate with a live software update on standard watches, or it may be unique to a new product like the Apple Watch 6. Apple needed to introduce new hardware to activate its ECG feature, so it may be a similar situation for the introduction of blood oxygen monitoring. We expect to hear more about watchOS 7 and iOS 14 at WWDC 2020 in June this year, so we can hear it at Apple's big software event. If not, we'll probably wait until September to see if the company unveils an Apple Watch 6 when the iPhone 12 is scheduled to launch in September. Via MacRumors
