Blood Pressurewatch

The biggest advantage of this technology is that it is non-invasive and non-intrusive. As mentioned earlier, current outpatient and home blood pressure measurement methods cannot achieve continuous, and the cuff device used in the oscillometric method will pass intermittent It may disturb the user's sleep, and may even cause harm to a certain extent, such as long-term inflation.

Apple's new patent mentions that the watch can assess blood pressure from the pulse: "By processing the data from the pulse arriving at the sensor, it calculates when the blood pressure pulse generated by the blood pumped by the left ventricle reaches the wrist". This means that users need to wear electrodes or some other form of sensor to achieve this new continuous blood pressure monitoring feature with the Apple Watch.
