FUNCTIONING
1 After applying the armband, use the bulb to pump up to approximately
20 mmHg beyond the level of individual systolic pressure: in other words,
until the brachial artery is blocked (maximum level). It is essential that
the person being measured remains seated and calm, and that his/her
forearm is resting at heart level, with the inside part facing up.
2 To measure blood pressure, turn the release/deflation screw on the bulb,
unscrewing it slowly in a counter-clockwise direction. The ideal deflation
speed is around 2-3 mmHg/sec.
Visually check deflation speed: on the scale, the indicator must move
at a speed of between 1 and 1.5 gradations per second.
The models featuring automatic deflation of the gauge, which automatically
regulates deflation speed at 2-3 mmHg/sec. Simply press the valve up to
the first pressure point.
3 Due to the gradual decompression, your blood starts to run through
the brachial artery again, which in turn causes an initial pulsation, that is
clearly perceived by the phonendoscope: the pressure indicated on the
gauge needle at the exact moment this first beat is recorded is referred
to as the "systolic or maximum pressure".
Systole = maximum pressure level when the heart contracts and blood
is pushed into the blood vessels.
As you proceed with decompression, the pulsations gradually decrease
until they suddenly disappear or become so low as to be imperceptible.
The pressure indicated by the gauge needle at the moment the pulsations
disappear is referred to as the "diastolic or minimum pressure".
Diastole = minimum blood pressure level when the heart muscle
is expanding and refilling with blood.
4 Now completely open the release valve until air begins to come out of the
armband. Blood pressure measurement is now completed.
MAINTENANCE
1. Gauge and bulb
Cleaning: The gauge and bulb can be wiped with a damp cloth.
Sterilization is not necessary, as the parts do not come into direct contact
with the patient's body.
2. Armbands
Cleaning: After removing the plenum chamber, the liners can be wiped with
a damp cloth, or you can wash them with soap and cold water. If you use this
second method, rinse the armbands with clean water and leave them to air
dry. Nylon armbands must not be ironed.
The plenum chamber and tubes can be wiped with a damp cotton cloth.
