4.2 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.
4.2A 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 wrist (normally left) and in the same
posture. Do not switch between right and left wrists while recording your blood
pressure as there may be a difference of up to 10 mmHg pressure between the
two wrists.
