Correct patient hook-up is very important. Experience has shown that a lot of troubles can be
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 2: Palpating the arm). Upper clothing should be taken off!
Pulled up garments should not jam the upper arm.
D.2.2
Position of the cuff
The cuff should be placed on the upper arm, so that it is positioned about 2 cm above the
elbow close to the heart level (Fig 3: Cuff position). Place the microphone on the position that
you palpated.
