5. Measurement Procedure
Please note: You should always be seated 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
measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Always perform measurements at the same time of day, since 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 quiet conditions.
• 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 muscles in the
measurement arm during measurement. Use a cushion for support and rest your arm
on a table.
• If the upper arm artery lies considerably lower or higher than the heart, a false higher
or lower blood pressure will be measured!
*A variation of 6" between cuff and heart level can result in a reading error
of + or - 10mm Hg.
• Cuffs that do not fit properly result in false measurement values. Selecting the correct
cuff is extremely important. The cuff size is dependent upon the circumference or
distance arround your upper arm measured in the center. The permissible range is
printed on the cuff. If this is not suitable for your use, please contact
Note: Use only clinically approved
manufactured and tested.
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• Repeated measurements without rest allows blood to accumulate in the arm. This can
lead to false results. Measurements should be done after a 5 minute rest to ensure
accuracy.
