Common sources of error:
Note:
Comparable blood-pressure measurements always require the same conditions! These are normally always quiet conditions.
All efforts by the patient to support the arm can increase the blood-pressure. Make sure you are in a comfortable, relaxed position
and do not activate any of the muscles in the measurement arm during the measurement. Use a cushion for support if necessary.
If the arm artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood-pressure will be measured! (Each
15cm difference in height results in a measurement error of 10mmHg)
Cuffs that are too narrow or too short result in false measurement values. Selecting the correct cuff is of extraordinary importance.
The cuff size is dependent upon the circumference of the arm (measured in the centre). The permissible range is printed on the cuff.
Note:
only use clinically approved Original-Cuffs!
A loose cuff or a sideways protruding air-pocket causes false measurement values.
With repeated measurements, blood accumulates in the respective arm, which can lead to false results. Correctly executed blood-
pressure measurements should therefore fi rst be repeated after a 1 minute pause.
7.6. Taking your blood pressure reading
For model PRO-33 only
(Picture 5, 5-1, 5-2, 5-3, 5-4)
After applying the cuff and your body is in a comfortable position, press the “START” button. A beep is heard and all display characters
are shown for self-test. See picture 5. Please contact the service center if segment is missing.
a. The LCD will momentarily display the last measurement stored in the memory. See picture 5-1. If the monitor has no meas-
urement stored in the memory, the LCD will display show “0” for blood pressure and pulse rate. See picture 5-2.
Picture 5 Picture 5-1 Picture 5-2 Picture 5-3 Picture 5-4
b. Then the monitor starts to seek zero pressure. See picture 5-3.
c. The monitor in fl ates the cuff until suf fi cient pressure has built up for a measurement. Then the monitor slowly releases air
from the cuff and carries out the measurement. Finally the blood pressure and pulse rate will be calculated and displayed
on the LCD screen. Irregular heartbeat symbol (if any) will blink. See picture 5-4.
