5.3 Fitting the arm cuff
a. Pass the end of the cuff (with sewn-in rubber stopper)
through the metal D-ring to form a loop. The Velcro
closure should be facing outward. If assembled correctly,
the metal D-ring should not touch the skin when the cuff
is looped around the arm.
Note: Skip this step if the cuff has already been
prepared.
b. Insert left arm through the cuff loop and position the
cuff on the upper arm. The tube should point in the
direction of the lower arm.
c. Adjust the cuff position on the upper arm. The lower
edge of the cuff should be approximately ¾-1” (2-3cm)
above the elbow. The tube and “ARTERY MARK” should
be aligned with the inner side of the arm.
Important: The red line along the edge of the cuff must
lie exactly over the artery which runs down the inner
side of the arm.
d. Tighten the free end of the cuff and secure with the
Velcro closure. The cuff should fit snugly on your upper
arm such that you can fit 2 fingers between the cuff and
your upper arm. Any clothing that restricts the arm
should be removed prior to measurement.
e. Lay the arm on the table or support cushion with the
palm upward. The arm cuff should be at the same level
as the heart. Check to make sure that the tube is not
kinked.
f. Remain seated comfortably for about two minutes
before starting measurement.
