According to reports, currently, Apple is working on at least two new upgrades of the health-related features of Apple Watch that includes a blood oxygen detector. The other is removing the 120 beats per minute (BPM) limitation for the ECG feature. This report is based on an exclusive look into the iOS 14 code snippets.
9to5Mac reported that Apple Watch will send a notification when it detects blood oxygen below a certain level. This means by its functionality, it will be similar to that of the heart rate notification. However, the report does not mention clearly whether this blood oxygen detector will require new hardware or software tweaks. Some experts are expecting it to be an Apple Watch Series 6 feature.
Now, as the stat goes, a blood oxygen level between 95 to 100 percent is considered healthy, while below 80 percent may lead to heart and brain problems. In this above-mentioned report, it is said that the current generation Apple Watch is believed to be capable of measuring blood oxygen levels through its built-in heart rate sensor. Recently, Fitbit has already introduced this feature but experts are believing that Apple has the potential to offer a much-ophisticated version of this sensor by using the Electrocardiogram feature which is present in the Apple Watch Series 4 and Apple Watch Series 5.
The report also suggests that Apple is also working its level best to upgrade the ECG feature on the current Series 4 and Series 5 models of Apple Watch. Currently, this ECG feature has the potential to read inconclusive ECG readings with heart rates ranging from 100 and 120 BPM. There will be a new update soon that will remove these limitations. Apple Watch models got this feature from Apple Watch Series 4 onward which was launched in 2018.
