Selecting The Correct Cuff; Connecting The Pump Ball; Taking A Blood Pressure Measurement Using This Device; Appearance Of The Heart Arrhythmia Indicator For Early Detection - Microlife BP A50 Mode D'emploi

Selecting the correct cuff

Microlife offers 3 different cuff sizes: S, M and L. Select the cuff size
to match the circumference of your upper arms (measured by close
fitting in the centre of the upper arm). M is the correct size for most
people.
Cuff size for circumference of upper arm
S 17 - 22 cm (6.75 - 8.75 inches)
M 22 - 32 cm (8.75 - 12.5 inches)
L 32 - 42 cm (12.5 - 16.5 inches)

Only use Microlife cuffs.
Contact your local Microlife Service if the enclosed cuff 8 does

not fit.
Connect the cuff to the device by inserting the cuff connector 9

into the cuff socket 4 as far as it will go.

Connecting the pump ball

Connect the pump ball AT to the device by firmly inserting the
connector AK into the pump ball socket 5.
3. Taking a Blood Pressure Measurement using this
Device
Checklist for taking a reliable measurement
1. Avoid activity, eating or smoking immediately before the
measurement.
2. Sit down for at least 5 minutes before the measurement and relax.
3. Always measure on the same arm (normally left).
4. Remove close-fitting garments from the upper arm. To avoid
constriction, shirt sleeves should not be rolled up - they do not
interfere with the cuff if they are laid flat.
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 2 cm above the elbow.
• The artery mark located 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. Switch on the device and wait until «0» appears in the display
and the arrow «» BT starts to flash.
7. Take the pump ball in your free hand (the arm you are not
measuring from) and pump up the cuff. Watch the pressure indi-
cation in the display and pump approx. 40 mmHg higher than
the expected systolic value (the upper value). If you have not
BP A50
pumped enough, a flashing arrow «» BT will appear telling
you to pump higher.
8. After pumping, the measurement is taken automatically. Relax, do
not move and do not tense your arm muscles until the measure-
ment result is displayed. Breathe normally and do not talk.
9. During the measurement, the heart symbol AN flashes in the
display and a beep sounds every time a heartbeat is detected.
10.The result, comprising the systolic AQ and the diastolic AR blood
pressure and the pulse rate AS is displayed and a long beep is
heard. Note also the explanations on further display symbols in
this booklet.
11.When the measurement has finished, press the quick-acting
discharge valve 6 in order to release any remaining air in the
cuff. Remove the cuff.
12.Switch off the device. (The monitor does switch off automati-
cally after approx. 1 min.).

You can interrupt the measurement at any time by pressing
the quick-acting discharge valve 6 (e.g. if you feel uneasy
or notice an unpleasant pressure sensation).
4. Appearance of the Heart Arrhythmia Indicator for
early Detection
This symbol AM indicates that certain pulse irregularities were
detected during the measurement. In this case, the result may
deviate from your normal blood pressure – repeat the measure-
ment. In most cases, this is no cause for concern. However, if the
symbol appears on a regular basis (e.g. several times a week with
measurements taken daily) we advise you to tell your doctor.
Please show your doctor the following explanation:
Information for the doctor on frequent appearance of the
Arrhythmia indicator
This device is an oscillometric blood pressure monitor that also
analyses pulse frequency during measurement. The device is
clinically tested.
The arrhythmia symbol is displayed after the measurement, if
pulse irregularities occur during measurement. If the symbol
appears more frequently (e.g. several times per week on
measurements performed daily) we recommend the patient to
seek medical advice.
This device does not replace a cardiac examination, but serves
to detect pulse irregularities at an early stage.
