Draw the cuff close. Place the free end outwards
over the upper arm (see Illustration) and close the
velcro fastening.
The cuff should fit firmly around the upper arm,
but not exert any pressure on the artery before in-
flation. If you can insert a finger between cuff and
upper arm, the cuff sits correctly.
11.) Put on the stethoscope allowing the earpieces of
the head frame to fit well inside your ears. These
arms can be rotated within their spring so that
they can be positioned individually.
12.) Now place the arm with the cuff back on the table,
comfortably, slightly angled, resting.
Take the manometer into your right hand, holding
it around the pump, with the thumb and forefigner
on the valve screw. Close the valve with a right turn
and pump up the cuff steadily, watching the
manometer.
Continue to pump until the indicator on the
manometer exceeds your usual blood pressure by
ca. 30 mmHg.
Should you still hear pulsing sounds through the
stethoscope, continue to inflate until these sounds
stop, which indicates that the circulation is
disrupted.
13.) Open the valve very slightly with thumb and
forefinger and watch the slow decrease in
pressure on the manometer. The rate of deflation
between systole and diastole should be in the
range of 2 – 3 mmHg per second, ie there should
be an interval of ca. 20 – 25 seconds for the
pointer on the scale to move from 150 to 100. To
avoid a reading error, read the pressure values
perpendicular to the scale.
– When you hear the first clear arterial
sound (knocking sound) through the
stethoscope you can read the systolic
(upper) blood pressure on the manometer
scale.
– When the arterial sound stops, you can
read the diastolic (lower) blood pressure.
