Fitting The Cuff; Measuring Procedure - Microlife BP 3BE0-4 Manual De Instrucciones

• If the wrist artery lies considerably lower (higher) than the heart, an erroneously higher (lower)
blood-pressure will be measured! (Each 15 cm difference in height results in a measurement
error of 10 mmHg!)
• A loose cuff causes false measurement values.

5.3. Fitting the cuff

a) Remove all eventual objects and jewellery (e.g. wrist-
watch) from the wrist in question. Draw the cuff over
the wrist.
b) The distance between the cuff and the hand should be
approx. 10 mm.
c) Secure the cuff with the fastener, so that it lies
comfortably and not too tight, whereby no space
should remain between the cuff and the wrist.
d) 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.

5.4. Measuring procedure

After the cuff has been appropriately positioned and the
setting of the pressure pre-selection has been undertaken,
the measurement can begin:
a) Press O/I button to put the device into operation
b) Press the START button – the pump begins to inflate the
cuff. In the display, the increasing cuff-pressure is
continually displayed.
c) After reaching the inflation pressure, the pump stops and the pressure
slowly falls away. The cuff-pressure (large characters) is displayed
during the measurement. When the device has detected the pulse, the
heart symbol in the display begins to blink and a peep tone is audible
for every pulse beat.
