a) Put the end of the cuff (with fastener) through the metal ring,
making the cuff a cylinder (ignore this step if your cuff is already set
up). Proper assembly allows the Velcro
®
to match up properly.
b) Place the cuff around your arm. Make sure the bottom edge of the
cuff is about 1” (2-3 cm) above the elbow joint. Adjust the cuff so
that the rubber tubing under the cuff lies over the brachial artery,
which runs on the inside of the arm (see Fig. B). The red material
should be over the brachial artery.
c) Pull the cuff and tighten it by attaching the Velcro
®
fastener.
Normally, the left arm is used, unless there is a physical reason for
using the right arm.
d) The cuff should fit snugly around the arm, but not too tight. You
should be able to fit two fingers under the cuff.
e) Place the arm on the table (palm facing upwards) so that the cuff is
at the same level as the heart. Make sure there is no kink in
the hose.
