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 arms while recording your blood pressure as there
may be a difference of up to 10mmHg pressure between the two wrist.
• 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.
• 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.
• Do not lean backward or bend your wrist inward while taking a measurement.
4.2B Fitting the wrist
a) Remove all accessories (watch, bracelet, etc.) from
your left wrist. If your physician has diagnosed you
with poor circulation in your left arm, use your right
wrist.
b) Roll or push up your sleeve to expose the skin.
c) Apply the cuff to your left wrist with your palm
facing up and the LCD display facing you.
