I always end up with my arm almost shoulder height resting on some bin on the side of the blood pressure device cart thing.

I wonder why they can't use an ergonomic chair with two appropriate-height support arms.

Your doctor should see it though, unless they don't stay next to you and thus can't (but I know mine use it more like a first control test, and would always do a manual test before prescribing anything).

YMMV, I'm in France.

PS : with that said, this here is even more different since it's in a watch, and I would not trust it for anything other than "hey, maybe go check at a doctor"

At least that’s what happened to me.

To be fair though, this high readings problem at the doctors office went away when I lost weight (from a BMI of 25 to a BMI of 22. both in normal weight range).

The breathing disturbances notifications work in a similar way. They alert you to potential sleep apnea, but then you need to do an at-home or in-lab sleep study in order to get a diagnosis.

Of course. The purpose of this feature is to tell the right people that they might have a problem, and that they should ask a doctor about it - just like they've done in the past with AFib detection.
