I have three blood pressure cuffs

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

I had my blood pressure tested several times over the course of the month and each time it was high, weirdly high, like 160/100. If I drove in, weirdly high. If I cycled in, weirdly high. If I got another reading after sitting quietly in the waiting room reading my book for half an hour, weirdly high.

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?

Blood pressures at this level can be observed from time to time. It’s not an instant death level.

Getting multiple readings is a good idea, but I would caution against picking the reading you like the most as the one which you believe to be correct.

You should also know that there are some conditions where high blood pressure can be transient. Some of these are very serious (tumors which secrete hormones which spike blood pressure). Having occasional scary high readings mixed in with occasional normal readings is actually typical with some of these conditions.

If I had any measurements show up that high I would invest in a cheap at home blood pressure device. They can be as cheap as $20. Then I’d collect a lot of measurements over several days.
