5.1. Before the measurement:
• Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these factors influence the measurement result. Try and find
time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes before the measurement.
• Remove any garment that fits closely to your upper arm.
• Measure always on the same arm (normally left).
• Attempt to carry out the measurements regularly at the same time of day, since the blood-pressure changes during the course of the day.
5.2. 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 depend-
