Pump Ball - Microlife BP AG1-30 Manual

• Make sure that the cuff is positioned 2 cm above the elbow.
• The artery mark on the cuff (ca. 3 cm long bar) must lie over
the artery which runs down the inner side of the arm.
• Support your arm so it is relaxed.
• Ensure that the cuff is at the same height as your heart.
6. Any improper setup or damage to the stethoscope will cause
distorted sound or poor sound transmission causing inaccurate
readings.
7. Proper deflation rate is essential for an accurate reading.
Practice and master a recommended deflation rate of 2-3 mmHg
per second or a drop of 1-2 marks on the manometer 1 for each
heartbeat.
Measuring procedure
1. Place the chest piece 6 underneath the cuff 2 or 1-2 cm
below it. Make sure the chest piece is in contact with the skin
and lies on the brachial artery.
2. Plug in the ear piece 7 and check, if the chest piece is placed
correctly, so that the Korotkoff sounds appear the loudest.
3. Close the valve 4 on the pump ball 3 by turning the screw
clockwise. Do not over-tighten.
4. Take the pump ball 3 in your free hand (the arm you are not
using to measure) and pump up the cuff. Watch the pressure indi-
cator on the manometer 1 and pump up to approx. 40 mmHg
higher than the expected systolic value (the upper value).
• Inflate to 200 mmHg if you are not sure about the expected
value.
5. Open the valve 4 slowly by turning the screw counter clock-
wise whilst holding the stethoscope chest piece 6 on the
brachial artery. Listen carefully as the cuff begins to deflate.
Note the reading on the manometer 1 as soon as you hear a
faint, rhythmic tapping or thumping sounds. This is the
systolic blood pressure reading.
6. Allow the pressure to continue dropping at the same deflation
rate. Note the reading on the manometer 1 as soon as the
thumping sound stops. This is the diastolic blood pressure
reading.
7. Deflate the cuff completely.
8. Repeat the measurement at least two further times and record
your values, date and time immediately after finishing the
measurements.
9. Remove the cuff and the stethoscope.
