for support if necessary.
•
If the wrist artery lies considerably lower or higher than the heart, an
erroneously higher or lower blood pressure will be measured! (Each 15cm or
5.9” difference in height results in a measurement error of 10mmHg!)
•
A loose cuff causes false measurement values.
•
With repeated measurements, blood can accumulate in the respective arm,
which can lead to false results. Correctly executed blood pressure
measurements should therefore first be repeated after a 1 minute pause or
after the arm has been held up in order to allow
the accumulated blood to flow away. (Does not
apply to a Life Fitness AveragingMode™
measurement.)
5.3. Fitting the cuff
a) Remove all objects and jewelry (e.g. wristwatch)
from the wrist in use. Put the cuff over the wrist
with the monitor face on the inside of the wrist.
b) The distance between the cuff and the hand should
be approx. 1/2” (10 mm).
c)
Secure the cuff with the Velcro™ fastener, so that
it lies comfortably and not too tight. No space
should remain between the cuff and the wrist.
d)
Lay your arm on a table, with your palm upwards.
Support your arm with a cushion, so that the cuff
rests at about the same height as your heart. Do
not hold or support the cuff with your free hand.
Remain still for 5 minutes before beginning a
measurement.
