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

In the morning before breakfast,
2 hours after dinner, before taking
medication.
Avoid coffee and smoking within the
hour, and no exercise 30 minutes
before measuring.
Do not speak while taking the
measurement.
Sit with legs uncrossed so as not to
restrict blood flow.
Ensure that the BP monitor is level
with the heart while the arm is
supported on the table.

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 and reliable 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.
