Apple is working on improving the health-related features of the Apple Watch, and one of the news is one that has been talked about for a long time: oxygen saturation. In addition, it will also improve the electrocardiogram function that has been present from the Apple Watch Series 4.
The information brings it to us 9to5Mac And it seems to confirm something that has been talked about for a long time. The Apple Watch might be able to detect oxygen levels in the blood, which is medically known as "Oxygen Saturation" and that it is affected in many diseases, both acute and chronic. The Apple Watch would be able to perform that measurement as it measures the heart rate right now, and send us notifications if you detect that levels have dropped below a specific level, which can probably be modified to suit each person.
Oxygen saturation can be affected in chronic respiratory diseases such as bronchitis, pulmonary emphysema or asthma, in heart diseases, and in other acute diseases such as asthma attacks, pneumonia, etc. After the advance that has been for many users that their Apple Watch monitor their heart rate or allow them to perform an electrocardiogram, this new functionality would help many people with diseases in which this measurement is important. Especially since without user intervention, The Apple Watch would always be monitoring the oxygen level, and would warn when an anomaly was detected.
Apple would also be working on improve electrocardiogram function, which is limited when the heart rate is above 120 beats per minute. This last improvement could come in software update mode, while the measurement of oxygen levels should arrive with a new device that incorporates the appropriate sensors for it. The two measures (heart rate and blood oxygen levels) could be used to finally launch another feature we've been talking about for a long time: sleep monitoring.
