I have high blood pressure, managed with a low dose of medication. I've had plenty of advice from my PCP and other actual doctors on how to take blood pressure - how to sit, how long to sit still, how to position your arm, etc.
It is remarkable how many medically-adjacent professionals are bad at this. My dentist starts my sessions with a blood pressure reading - theoretically in case they have to numb me or something, probably because it's billable or whatever. What always seems to happen is that I get in for my appointment (driving, which can be stressful even if I'm not running late), they take me to the chair within 2 minutes max, immediately put some sort of wrist cuff on me, hold my arm at an angle that is not what most actual doctors have recommended to me and take a reading that is often high enough to surprise both the hygenist and myself.
The thing is that I have two sufficiently-calibrated Omron units, one at home and one at the office. I take my blood pressure often enough to know what it usually is (and my real doctor takes it at least twice a year). That is to say that no, it's not 200/160 or whatever nonsense the dentist thinks it is and you'd think that with a very small amount of reading they'd know better.
I was at the Dr last week and my first BP reading was 154/95, a second reading a few minutes later was 141/89. The doctor asked for one more reading before I left.
The medical assistant gave me my vaccines and then took my BP, 130/81 right after a Hep B and COVID vaccine. I told the tech that needles didn’t bother me at all, she believed me after she saw my blood pressure :)
Just spent half a day reverse engineering a Windows virtual printer driver (for work) and had to force myself to stop spending the rest of the day doing it.
They all give me different numbers, by a lot sometimes
btw you think they ever clean those devices?
you think healthy people go to pharmacies?
I won't even touch the signature pen, imagine what's on that
They wanted me to start on all sorts of medications immediately.
The second-last time, they got a reading of 220/130, and were going to get an ambulance to take me into hospital immediately.
Er, hang on a minute, folks.
That's beyond "hypertension crisis" and well into "incompatible with life" levels. That's the kind of pressure I see in hydraulic servo feedback channels, not living things.
They grudgingly agreed that someone with high blood pressure probably ought not to be making as much sense as I was, although what would I know about it, they're the professionals, etc etc.
The next time I noticed the automatic blood pressure cuff had a fresh new calibration sticker on it.
130/90. Not bad, for a reading taken at the doctor's surgery.
I wonder how many people are on medication they just plain don't need because of a plainly faulty sphyg though?
Maybe? Do they clean the shelves? Arm-to-arm contact isn't exactly a big threat.
> you think healthy people go to pharmacies?
Yes. Of course. Those free blood pressure machines are generally found in drug stores that have a small pharmacy section. The vast majority of people there are there because they're shopping. There are probably more people who come in to buy mascara than people who come in because they're sick. If you're sick, someone else goes to the pharmacy for you.
"stupid in ways that made me think" is (IMO) a really good summary of how AI is useful, as well as its pitfalls.

This is often isn't possible, but it's a reason doctor visits usually drop you in a room by yourself with a machine that will take multiple measurements with a lengthy delay between. Though that's where the white coat thing comes into play and people are stressed about a doctor coming in, etc.

It also never helps to explain that this has happened many times before and that I have a reasonably high quality BP measurement device at home (most recently the exact same Braun model) that gives me decent measurements when I'm at rest/relaxed. They just look at me like I'm an idiot. How could a civilian conceivably perform such a complex measurement?
Then I get the predictably insanely high measurement and they look satisfied. Gotcha!
Please bring on the AI doctors.

I have to take daily BP measurements during titration for ADHD medication. (Using an _A&D UA-611 Plus_ machine at home.)
I can put the cuff on my arm and sit at my desk for 20 minutes to be nicely rested and calm, and then take 5 different measurements with a few minutes between each one. They'll vary quite wildly (anything from, say, 115/75 to 135/90) despite not moving between measurements or having any reason to be more or less agitated. I generally just ignore the low/high outliers and average the others. There's no pattern either, sometimes the outliers are first, sometimes last.
Also it's not just the monitor I have at home, the same is true of a probably more trustworthy machine in a clinical setting. I mentioned this to my doctor when I last visited and we saw the same thing with multiple measurements using a more sophisticated machine at the clinic.

* the position of both of your arms, and the angle your elbows are bent at matters. make sure the edge of your desk isn't pushing into your forearm.
* same goes for both of your legs. make sure you're sitting with legs uncrossed, relaxed angles, make sure the edge of your chair isn't pushing into the back of your thighs excessively.
* control your posture. slouching seems to have an effect too, but I'm unclear on the mechanism.
Anecdotally, the nurses at the doctor's offices I go to rarely (~never) bother to control for any of this other than telling me not to cross my legs. So while I fully believe white coat hypertension is a thing, I also think there's a lot of poor control of variables here. If you look up the AMA/AHA guidelines for blood pressure, the ranges they offer are predicated on some very prescriptive protocols for measurement.. which I virtually never see adhered to.

Doesn't it take more than a few minutes for one's circulation to return to normal after a BP measurement?

It really amazes me how people whose job it is to take blood pressure don’t recognize the stress situations that people are in might result in abnormal readings.
