This is an interesting point. I know for sure that I have been taught in school to never trust the electronic BP machines, since they can be pretty far off for some (but not all) people.
Instead, using a sphygmomanometer is much more likely to give accurate results.
Anecdotally, I always have a super weird initial blood pressure reading when I go to the doctor and they use the electric machine (one time it was 112/95), but when it is rechecked with a sphygmomanometer it tends to level out at somewhere around 130/85.
- hedora 3y agoIf you have a portable meter, you can always take it to the doctor and do a back-to-back or simultaneous reading. You will probably find that your blood pressure varies more over a 10 minute window than the difference in readings between the two meters.
- jaclaz 3y agoThe way a manual sphigmomanometer works is different from the way the electronic ones do[1], I would not be surprised if for a few people something else affects the reading of the pressure in the arm band.
