5.2.6 Microphone Position
Before applying the cuff, check the position of the micro-
phone inside the red pocket (on the inside of the cuff):
When the microphone is inside the pocket, its
metal side
must face the arm
.
Figure 5 – 5: Correct microphone position
The center of the microphone must be located exactly
on the
brachial artery
. Locate the artery by palpation
if required.
The
red tab
identifies the position of the microphone.
The accurate placement of the microphone is the primary
condition for reliable pressure measurement during exer-
cise tests. The cuff must be applied directly on the skin,
it may not be applied on top of clothing, paper, etc.
Apply the cuff approx.
2 cm above the bend of the elbow
.
The cuff should be
tight
, but it should not constrict blood
vessels. Make sure that the cuff
cannot shift
when the
patient moves during the exercise test.
