Taking A Blood Pressure Measurement Using This Device - Microlife AFIB BT Manual

determined in this way is more reliable than one produced by a single measurement. AFIB
detection is only activated in AFIB/ MAM mode.
After pressing the START/STOP button (1), the selected AFIB/ MAM mode appears in the
•
display as the MAM-symbol (25).
The bottom, right hand section of the display shows a 1, 2 or 3 to indicate which of the 3
•
measurements is currently being taken.
There is a break of 15 seconds between the measurements (15 seconds are adequate according
•
to «Blood Pressure Monitoring, 2001, 6:145-147» for oscillometric instruments). A count down
indicates the remaining time.
The individual results are not displayed. Your blood pressure will only be displayed after all 3
•
measurements are taken.
Do not remove the cuff between measurements.
•
If one of the individual measurements was questionable, a fourth one is automatically taken.

4. 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). It is recommended that doctors perform
double arm measurements on a patients first visit in order to determine which arm to measure in
the future. The arm with the higher blood pressure should be measured.
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. Slide the lock switch (13) down to the «unlock» position. Press the START/STOP button (1) to
start measuring.
7. The cuff will now pump up automatically. Relax, do not move and do not tense your arm
muscles until the measurement result is displayed. Breathe normally and do not talk.
8. When the correct pressure is reached, the pumping stops and the pressure falls gradually. If the
required pressure was not reached, the device will automatically pump some more air into the cuff.
9. During the measurement, the pulse indicator (22) flashes in the display.
10 The result, comprising the systolic (16) and the diastolic (17) blood pressure and the pulse rate (18)
is displayed. Note also the explanations on further display symbols in this booklet.
11. When the device has finished measuring, remove the cuff.
