see the individual readings one time immediately following an
Averaging Mode measurement. See section 5.6.
Do not remove the cuff between measurements.
6. MEASUREMENT PROCEDURE
6.1. Before Measurement:
Avoid eating and smoking as well as all forms of exertion directly before
•
measurement. These factors influence the measurement result. Find time
to relax by sitting in an armchair in a quiet atmosphere for about ten
minutes before taking a measurement.
Remove any garment that fits closely to your upper arm.
•
Always measure on the same arm (normally left).
•
Always compare measurements taken at the same time of day, since blood
•
pressure changes during the course of the day, as much as 20-40 mmHg.
6.2. Common Sources of Error:
NOTE:
Comparable blood pressure measurements always require the same
conditions! Conditions should always be quiet.
All efforts by the user to support the arm can increase blood pressure.
•
Make sure you are in a comfortable, relaxed position and do not flex 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 or higher than the heart, an
•
erroneously high or low blood pressure will be measured! Each 15cm (6
inch) difference in height between your heart and the cuff results in a
measurement error of 10 mmHg!
Cuffs that are too narrow or too short result in false measurement values.
•
Selecting the correct cuff is extremely important. Cuff size is dependent
upon the circumference of the arm (measured in the center).
The permissible range is printed on the cuff. If this is not suitable for your
