pressure, also the real time heart rate and Korotkoff tone are indicated. Each heart rate is

avoided when the rules below are kept in mind. Especially BP measurement using Korotkoff
tones under stress requires accurate preparation.
D.2.1
Apply the cuff
On the inside of the upper arm you can feel the brachial artery. Palpate the brachial artery to
ensure proper placement. The best place for the microphone is where you can most clearly
feel the pulse (Fig. 23 Palpating the arm). Upper clothing should be taken off!
Pulled up garments should not jam the upper arm.
