Fitting The Cuff - boso clinicus I Mode D'emploi

6
– relax as much as possible and keep silent while his/her
blood pressure is being measured
– be calm for 5 minutes before the first reading
The following phases are recommended in the case of aus-
cultatory measurement
– adults: phase V (K5)
– children aged 3 to 12: phase IV (K4)
– pregnant women: phase V (K5), except when sounds are
audible when the cuff is deflated: in this case phase IV
(K4) Korotkoff sounds should be used.
K5 is the point at which tones heard through the stethoscope
are no longer audible
K4 is the point at which tones heard through the stethoscope
change from a clear sound to a muffled sound.
Inscriptions:
"mmHg" is the unit in which blood pressure is measured
"shock protected" = the instrument has been tested and fo-
und to work correctly after being dropped from a height of up
to one metre.

Fitting the Cuff:

The cuff must not be fitted over wounds as this could lead to
further injury.
Blood pressure must always be measured on the arm with
the higher pressure values.
To do this, first measure blood pressure on both arms and
subsequently always on the arm which produced the higher
reading.
Place cuff in such a manner that the lower cuff edge finishes
ca. 2 – 3 cm above the elbow and the centre of the rubber
bag rests on top of the artery.
Taking the Blood Pressure:
Inflate the cuff to above the systolic pressure. The air release
speed can be adjusted by rotating the valve screw.
The World Health Organisation (WHO) recommends a
deflation speed of 2 – 3 mmHg per second.
After the measurement is completed, fully open the ai
release valve to allow for the fast deflation of the cuff.
