How do you check someones blood pressure?
Blood pressure is how much force is being put on the walls of the blood vessels, and it’s messured with an inflatable cuff called a sphygmomanometer (my spell check didn’t pick it up, but that’s probably close) and a stethoscope. IF you have to do it at home, regularly, the best thing is to buy one of the electric ones. I’m sure any modern pharmacy will carry them.
