- elric 7y agoIt inflates the wristband and uses oscillometric measurements to estimate the BP. Source: the user manual (linked on the site near the bottom of the page). It's the same way most home blood pressure monitors work. It's not as accurate as good old mercury+stethoscope, but it's pretty decent. Generally speaking, measuring on the wrist further reduces accuracy. The absolute values might not be the most accurate, but I suspect the trend over months/years will be accurate enough.
- Gatsky 7y agoThank you.
- scotty79 7y agoI've seen recently cheapish fitness watches that claim to measure pressure. They need to be callibrated with actual pressure measurement and they measure changes for that point. It think by recording skin color as vessels dillate due to pressure increase. I'm guessing it's very inaccurate and floating. This one seems to do things the usual way (inflated wristband).
