BIOS 3MS1-4K - C Fitting the Wide Range Cuff

ATTENTION!
Comparable blood pressure measurements always require the same conditions with a peaceful and
calm environment. Ensure that you take measurements under the same conditions to obtain an
accurate estimate of blood pressure variation patterns.

3.3C Fitting the Wide Range Cuff
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” 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. C).
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.
