5.2 Common sources of error
Note:
Comparable blood-pressure measurements always require the same
conditions! These are normally always quiet conditions.
All efforts by the patient to support the arm can increase the blood-pressure.
Make sure you are in a comfortable, relaxed position and do not activate any of
the muscles in the measurement arm during the measurement. Use a cushion
for support if necessary.
The performance of the automated sphygmomanometer can be affected by
extremes of temperature, humidity and altitude.
Avoid compression or restriction of the connection tubing.
A loose cuff causes false measurement values.
With repeated measurements, blood accumulates in the respective arm, which
can lead to false results. Correctly executed blood-pressure measurements should
therefore first be repeated after a 5-minute pause or after the arm has been held
up in order to allow the accumulated blood to flow away (after at least 3 minutes).
5.3 Fitting the cuff
Insert air connector into air outlet shown in
left photo and please make sure the fitting of
the air connector completely and properly to
avoid air leakage.
a) The distance between the edge of cuff
and the elbow should be approx. 2~3cm.
b) Secure the cuff with the Velcro fastener,
so that it lies comfortably and not too
tight, whereby no space should remain
between the cuff and the arm.
c) Lay the arm on a table, with the palm
upwards. Support the arm a little with a
rest (cushion), so that the cuff rests at
about the same height as the heart. Take
care, that the cuff lies free. Remain so for
2 minutes sitting quietly, before beginning
with the measurement.
