3.1. Fitting the cuff
. Pass the end of the cuff through the flat
metal ring so that a loop is formed.
. Place the cuff over the left upper arm
so that tube is closer to your lower arm.
3. Lay the cuff on the arm so that the low-
er edge of the cuff lies approximately to 3
cm above the elbow.
4. Tighten the cuff by pulling the end and
close the cuff by affixing the velcro. There
should be little free space between the arm
and the cuff. Cuff that does not fit properly
results in false measurement values. Cloth-
ing must not restrict the arm. Any piece of
clothing which does must be removed.
5. Lay your arm on a table so the cuff is at
the same height as your heart. If the upper
arm artery lies considerably lower or higher
than the heart, a false higher or lower blood
pressure will be measured! A variation of 5
cm between cuff and heart level can result in
a reading error of + or - 0mm Hg.
Make sure the tube is not kinked.
. Remain seated quietly for two minutes
before you begin the measurement.
