> 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.
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.
