10.) D-Ring Velcro 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.
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.
