2.3 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.
2.4 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.
