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) Place the cuff over the left upper arm so that the tube is closer to your
lower arm.
c) Lay the cuff on the arm as illustrated. Make certain that the
lower edge of the cuff lies approximately one inch above the
elbow and that the tube is closer to the inner side of the arm.
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 closing 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. Any piece of clothing which
does, must be removed. Cuffs that don’t fit properly results in
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 5 minutes before you begin
the measurement.
