Apple Watch Series 6 Could Measure Blood Oxygen, Offer Improved ECG

Apple is working on further improving the health features of the Apple Watch. The company plans on adding the ability to detect blood-oxygen levels to its wearable. This feature is already found in selected Fitbit wearables.

Code found in an internal build of iOS 14 points to blood oxygen level monitoring coming to Apple Watch. A notification will be displayed when blood oxygen level drops below 80% which can lead to cardiac failure and cause other issues. At the moment, it is unclear if blood oxygen monitoring will require new hardware or not. If it does, then the feature will be limited to the upcoming Apple Watch Series 6 otherwise Apple could potentially bring the feature to its existing wearable lineup with the watchOS 7 update.

Additionally, Apple will improve the ECG functionality of the Apple Watch to ensure it is able to take proper ECG readings when the heart rate is between 100 to 120 beats per minute. Right now, Apple Watch Series 4 or Series 5 will show inconclusive ECG readings if the heart rate is between that range. It is again unclear if Apple will get rid of this limitation via software or it will be using new hardware on the Apple Watch Series 6 for this.

Apple Watch Series 6 is also expected to bring native sleep tracking to the wearable. Apple Watch Series 6 is looking like a major upgrade which makes sense since Apple Watch Series 5 was a modest upgrade and only introduced Always-On Display.
