8.BASIC RULES FOR MEASURING
•Avoid eating, smoking or any form of exercise prior to measuring. All these factors influence the result of the measurement.
•Take time to relax seated in an armchair, in a calm atmosphere, for ten minutes prior to measuring.
•While measuring, remain seated, calm and without moving or speaking.
•Remove any clothing that might put pressure on the arm.
•Always take the measurement on the same arm (normally the left) and, as much as possible, avoid moving it while measuring. If necessary, rest your arm on a cushion to keep it relaxed.
•Endeavour to take the measurements on a regular basis, at the same time of day and in the same conditions since arterial pressure changes in the course of the day.
•Do not take a measurement immediately after another. Wait for a few minutes, in a relaxed position, seated or lying down, before repeating measuring.
•If the armband is placed too far below or too far above the heart, the measurement will be altered showing a higher or lower pressure relative to the real values (for each 15 cm difference in height, the result of the measuring will alter by 10 mmHg.
•A poorly fitted armband or an air pocket along the sides leads to false measurements.
N.B.
To obtain comparable blood pressure measurement values, it is essential for them to be taken in identical conditions.
