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. 24 Cuff position). Place the microphone on the position
that you palpated.
Caution: Never place the cuff so that the microphone is located in the elbow.
Pull the cuff so tight, that it neither moves nor ties off the arm of the patient. By fasten the
cuff too tight or too loose, error measurements are caused.
Wrap the end of the cuff around the upper arm and close the Velcro fastening (Fig. 25
Mounting the cuff).
Ensure that the air hose from the monitor to the cuff is not compressed, crimped or damaged.
During ergometry the air hose should be handled and attached in such a way, that vibrations
and movement artefacts are avoided. Use the ringstrap to fix the tubes to the wrist to avoid
tensions on the cuff due to moving and pulling tubes.
During the measurement, which starts with inflation, the arm with the cuff should be
kept in rest. With ergometry it is most convenient for the patient to take the arm from the
handlebar of the ergometer and relax the arm with the cuff.
