Two new health-based features will appear on Apple Watch in the future. According to the site 9to5Mac, code snippets from iOS 14 indicate that theApple Watch will be able to detect the level of oxygen in the blood, in addition to the function of the electrocardiogram (ECG) will be improved.
Measuring the level of oxygen in the blood
Blood oxygen levels between 95 and 100% are considered healthy. Thereby, oxygen levels in the blood below 80% can cause impaired heart and brain functionality. The risk of respiratory or cardiac arrest is frequent after a continuous saturation of a low level of oxygen in the blood. Once the rate is measured by the Apple Watch, the watch will send a notification to the user when its oxygen level is too low, so similar to abnormal heart rate notifications current.
On the other hand, it is not indicated if this functionality will land with a software update (so, on almost all current Apple Watches) or if it will come with a hardware update (on the next Apple Watch suddenly). But Apple wouldn’t be the first (or only) manufacturer to offer this feature on its connected watch; indeed, it is already addressed by Fitbit and Withings.
Improvement of the electrocardiogram
Regarding the improvement of the ECG function, Apple is working to remove a current gap which is at the level thereof. The Apple Watch Series 4 and Apple Watch Series 5 currently offer inconclusive ECG readings for heart rates between 100 and 120 beats per minute. A future update – software or hardware – will remove this imperfection.
