Accurate blood pressure measurement requires resting for 5 minutes, a properly fitting cuff, arm at heart level, no crossed legs, and duplicate or triplicate readings twice daily for two weeks annually.

“correctly means sitting there for 5 minutes doing nothing resting before the blood pressure is checked it also means having a cuff that fits correctly having the arm at the level of the right atrium so about mid chest here uh not having your legs crossed when it's checked and I always like to check it in duplicate or triplicate and uh if a person can do that twice a day for a couple of weeks once a year again not a huge inconvenience in my view then they can have a real assessment of their blood pressure”
