Honestly I'm not sure what a single point-in-time reading even accomplishes. I've been hooked up to a continuous blood pressure monitor a few times and it's always fun to see how low I can get it. It seems pretty useless without seeing where it fluctuates over time not in a doctor's office.

How do these work? You can't stay compressed all the time? Is it intravenal?

The ones I've been hooked up to just compress every few minutes so not terribly fancy.

Once, when hospitalized, I had an arterial BP monitor that was continuous. The last systolic number I remember seeing before passing out from sepsis was in the 70s.

Aktiia makes a continuous optical blood pressure monitor that is available in the EU. It's like wearing a fitbit, but for bp. You calibrate it with a pressure cuff once a month.

I'm pretty sure they're going through fda approval in the USA now.
