Question posed by Lou: Is there such thing as a “live” blood pressure monitor?
Just like heart those heart rate monitor wrist watches, I was wondering if there is such thing as one that measures blood pressure and gives you a “live” measurement of it? It would be great so that one can just look and see how things that they eat/drink affect their blood pressure instantly.

No, there isn’t. Even if you’re an inpatient in the hospital, the machine checks your blood pressure about every ten minutes by inflating the cuff around your arm. There isn’t any machine that does it constantly.

Yes, there is … but it’s only used during major surgery because they have to put the monitor inside the blood vessel.
And things you eat and drink take as long as an hour to make it through the stomach, into the bloodstream and then affect BP.
Continuous monitoring of blood pressure will require cannula insertion into an artery. This is done only in an intensive care set up or in the cardiac catheterisation laboratory during procedures.
Intermittent blood pressure monitoring is feasible with ambulatory blood pressure monitors, which can be worn for 24 hours. This is non-invasive and does not need insertion of a cannula.
