a simple question that is puzzling not only me.
In taking a manual blood pressure, is it correct to re-pump to make sure you are precise on the systolic?
I'll be more precise: say I think I heard the first beat at 146 and I'm mow at 138 is it OK to go back on 150 to be sure of the 146, or do I have to go all the way down and retake the blood pressure?
Please, if you answer, I'd like the rationale, and if you add a link to the article, many points are assured to you. Looking around on the net, but finding nothing.
