K5 is the point at which the sounds heard with a stethoscope are
no longer audible.
K4 is the point at which the sounds heard with a stethoscope
vary from clear tapping to muffled.
Measuring blood pressure:
Attaching the arm cuff (instructions given for right-
handed users):
1. After pushing back the shirt sleeve or otherwise freeing
the upper arm of clothing, open the cuff‘s Velcro strap and
pull the cuff up over the upper left arm. The tube should
be positioned so that to point downward. The lower edge
of the cuff should stay approx. 2-3 cm above the elbow.
2. The artery pointer on the cuff (KaWe logo must be visible
on the outside) must be placed on the inside of the
upper arm near the palpating artery. If this artery cannot
be seen, it can be found by feeling 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 under the cuff
and positioned over the artery.
4. Make sure that the cuff is always at the heart level.
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 device gauge and hold the
left arm absolutely still.
4. If 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:
1. 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 affects the exactness
of 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 released 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 releasing the pressure, listen continuously for the
sound of the pulse in the artery 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 (diastolic
pressure).
Completing the measurement procedure:
1. Open the air release valve completely to let the air escape
completely from the cuff.
2. Remove the cuff from the arm and store the entire
instrument in its storage case.
Cleaning:
Gauge:
To clean the device, use only a soft, dry cloth.
Reusable cuff:
If necessary, wipe the cuff with a damp cloth.
Disinfection:
Gauge:
For disinfection of the device by wiping (minimum
exposure time of at least 5 minutes) it is recommended to use
the disinfectant Mikrozid sensitive liquid (manufactured by
Schülke & Mayr).
