Before Taking A Measurement
1.Avoid eating,drinking alcohol, smoking, exercising and bathing for
30 minutes before taking a measurement.
2.Stress raises blood pressure.Avoid taking measurements during
stressful times.
3.The cuff can be applied to your left or right wrist.Always measure
your blood pressure on the same wrist.
4.Measurements should be taken in a quiet place.
5.Position the unit at heart level throughout the measurement.
6.Remain still and do not talk during the measurement.
7.Keep a record of your blood pressure and pulse readings for your
physician.A single measurement does not provide an accurate
indication of your true blood pressure.You need to take and record
several readings over a period of time.Try to measure your blood
pressure at the same time each day for consistency.
8.Wait 30~60 seconds between measurements.The wait time allows
the arteries to return to the condition prior to taking the blood
pressure measurement.You may need to increase the wait time
depending on your individual physiological characteristics.
