Measuring Procedure; Malfunction / Troubleshooting - Microlife BP AG1-10 Mode D'emploi

5. Always ensure that the correct cuff size is used (marking on the
cuff).
 Fit the cuff closely, but not too tight.
 Make sure that the cuff is positioned 1-2 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 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 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 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.

4. Malfunction / Troubleshooting

If problems occur when using the device, the following points
should be checked and if necessary, the corresponding measures
are to be taken:
