5. Measurement Procedure
Note: You should always be seated and calm before and during measurement.
5.1. 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.
5.2. Common sources of error:
Note: Comparable blood pressure measurements always require the same co nditions!
•Conditions should always be quiet.
•All efforts by the user to suppo rt the arm can increase blood pressure. Make sure you are in a
comfortable, relaxed position and do not flex any of the mu scles in the measurement arm
during the measurement. Use a cushion for support if n e cessary.
• If the arm a rtery lies considerably lower or higher than the heart, an erroneously high or low
blood pressure will be measured! Each 25-30cm difference in height between your heart and
the cuff results in a measurement error of 10 mmHg!
Note: Only use approved cuffs!
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after a 1 minute pause or after
your arm has been held up in order to allow the ac cumulated blood to flow away. If you decide
to take your Averaging Mode measurement again, be sure to wait at least one minute
beforehand.
