any sites or links would be very accommodating"how do you filch blood pressure witha stethescope and a sphygmomonameter?
put cuff on bicep. steth on the elbow with the forearm up. pump to ~180. tolerate the air out slowly. when you first hear the heart belt remember that number. then hold on to letting it out slowly. when you are no longer able to hear the heartbeat, remember that number. and those are your systolic/diastolic pressures.
Here's a connect that will tell you adjectives about it.. It's really pretty easy once you hold had some practice.
