time to relax by sitting in an armchair in a quiet atmosphere for about ten minutes before the measurement.
• Remove any garment that ts 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 eorts 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 dierence in
height results in a measurement error of 10mmHg)
