Staying the Course -- 12/02/2019

I've looked at inexpensive smart watches. One that I looked at said that it was able to take blood pressure, and also blood oxygen percentage. They've removed that claim.
Blood pressure is probably way too difficult to accurately record - and it could vary depending on the tightness of the band. Sometimes they try to put way too much into a sub-$50 'smartwatch.'

Isn’t blood pressure constantly changing within that less than 20 pt range?

 

[Protimenow]

Yes. It's a moving target.

Not if you are sitting on the couch watching TV.

It probably varies, even if you're on the couch watching TV. (For example, if you're watching a rerun of Green Acres, it may go up if you laugh; if you're watching an action movie, it may go up during an action scene; if you're watching The Brady Bunch, it may drop precipitously).
