arm. The hose should be positioned so that it is point-
ing downward. The lower edge of the cuff should rest
approx. 2-3 cm above the elbow. 2. The artery symbol
on the cuff (KaWe logo visible on the outside) must be
placed on the inside of the upper arm near the pal-
pating vein (artery). If this vein cannot be seen, it can
be found by feeling for the pulse with the fingertips.
3. For the doctor's blood pressure measuring device,
a stethoscope is required in addition. The stethoscope
chest piece (membrane side) must be inserted un-
der the cuff and positioned over the artery. 4. Make
sure that the cuff is kept approx. level with the heart.
5. Using the Velcro closure, fasten the cuff firmly but
not tightly (leaving about 1-2 cm of space). 6. Prepare
the stethoscope for use (insert the ear pieces into your
ears).
Creating pressure: 1. Close the air-release valve on
the hand pump by turning the screw to the right. Do
not over-tighten the screw 2. Inflate the cuff quickly
and rhythmically with the hand pump and use the
diaphragm on the stethoscope to listen to the pulse.
3. During this process, watch the instrument gauge
and hold the left arm absolutely still. 4. When a pulse
can no longer be heard with the stethoscope, raise the
pressure in the cuff once again with the hand pump
by 30 mmHg.
Releasing pressure: Open the air release valve
slowly, so that the drop in pressure on the gauge is
approx. 2-3 mmHg/s.
Note: The speed of the pressure release greatly affects
the exactness of the measurement results. The pressure
must not be released too quickly or the point at which
the pulse restarts will be missed. If the pressure is re-
leased too slowly, the arm will be left too long without
the supply of blood because the pressure cuts off the
blood flow.
Determining the systolic pressure: 1. While re-
leasing the pressure, listen continuously for the sound
of the pulse in the vein with the stethoscope. When
the first pulse is heard, read the upper blood pressure
value (systolic pressure) and remember this value.
2. As the pressure is released even further, the pulses
will become quieter until they disappear completely.
Remember the last pressure value by which a pulse
was heard. This is the lower blood pressure value (di-
astolic pressure).
Completing the measurement procedure: 1.
Open the air release valve completely so that the pres-
sure may completely escape from the cuff. 2. Remove
the cuff from the arm and store the entire instrument
in its storage case.
Cleaning:
Monitor: To clean the unit, use only a soft, dry cloth.
Reusable cuff: If necessary, wipe the cuff with a
damp cloth.
Disinfection:
Monitor: To disinfect the unit, we recommend
wiping with the disinfecting agent mikrozid sensitiv
liquid (made by Schülke & Mayr). (Reaction time: min.
5 minute).
Reusable cuff: Wipe the cuff with a damp cloth
and clean with soap or disinfectant. The cuffs have
been tested to withstand the following recommended
disinfectants: Buraton liquid, Cidex®, Ethanol 70%,
Isopropyl-acohol 70%, Mikrozid® and Sporicidin®.
