Cuff size
Always choose the cu size suitable for the patient's arm.
The maximum arm circumference is indicated on the cu.

Before applying the cu, check the position of the micro‑
phone inside the red pocket (on the inside of the cu):
When the microphone is inside the pocket, its metal side
must face the arm.
aPPlyinG the Cuff
The center of the microphone must be located exactly
on the brachial artery. Locate the artery by palpation, if
required. The red tab identies the position of the micro‑
phone.
The accurate placement of the microphone is the primary
condition for reliable pressure measurement during exer‑
cise tests.
The cu must be applied directly on the skin, it may not
be applied on top of clothing, paper, etc. Apply the cu
approx. 2 cm above the bend of the elbow. The cu
should be tight, but it should not constrict blood vessels.
The cu may not move during the exercise test.
