3.3 Obtaining Accurate Measurements
Your blood pressure can vary based on numerous factors, physiological conditions and your surroundings.
Follow these guidelines to obtain accurate and error free measurements of your blood pressure and pulse rate.
3.3A Before Measuring
•
Avoid eating, smoking as well as all forms of exertion directly before the measurement. All these factors
influence the measurement result. Relax by sitting in an armchair in a quiet atmosphere for about
5 minutes before the measurement.
•
Always take measurements on the same arm (normally left) and in the same posture. Do not switch
between right and left arms while recording your blood pressure as there may be a difference of up to
10 mmHg pressure between the two arms.
•
Attempt to carry out the measurements regularly at the same time of day, since blood pressure changes
during the course of the day. The ideal time to measure your blood pressure is in the morning after you
wake up, before breakfast and physical activity, and in the absence of the urge to urinate.
•
Rest for 5 minutes sitting quietly and release all the tension in your body — especially the arm muscles
— before beginning with the measurement. Remain calm and quiet when the measurement is in process.
Do not speak or move your arm (as well as other body) muscles during the process.
3.3B Common Sources of Error
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.
ATTENTION
Comparable blood pressure measurements always require the same conditions with a peaceful
and calm environment. Ensure that you take measurements under the same conditions to obtain an
accurate estimate of blood pressure variation patterns.
•
If the arm artery lies considerably lower or higher than the heart, an erroneous value of blood pressure is
measured. Each 15 cm difference in height results in a measurement error of 10 mmHg.
•
A loose cuff 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 at least a 15 second pause or after the arm has
been held up in order to allow the accumulated blood to flow away.
