3.3C Fitting the Cuff
a) Pass the end of the cuff through the flat metal ring so that a loop is formed. The
closure must be facing outward. (Ignore this step if the cuff has already
been prepared.)
b) Wrap the cuff around your upper left arm. The rubber tube should be on the inside
of your arm extending downward to your hand.
c) Lay the cuff on the arm as illustrated. Make certain that the lower edge of the cuff
lies approximately ¾" to 1" (2 to 3 cm) above the elbow.
Important: The small white arrow (Artery Mark) on the cuff must lie exactly
over the artery which runs down the inner side of the arm.
d) Tighten the cuff by pulling the end and close the cuff.
e) There should be little free space between the arm and cuff. You should
be able to fit 2 fingers between your arm and the cuff. Clothing must not
restrict the arm. If any piece of clothing does, it must be removed. If the
cuff does not fit properly, you will get a false measurement values. Measure
your arm circumference if you are not sure of proper fit.
f) Lay your arm on a table (palm upward) so the cuff is at the same
height as your heart. Make sure the tube is not kinked.
g) Remain seated quietly for at least 2 minutes before you begin the measurement.
Comment:
If it is not possible to fit the cuff to your left arm, it can also be placed on the right
arm. However all measurements should be made using the same arm.
Comparable blood pressure measurements always require the same conditions
(relax for several minutes before taking a measurement).
