Before the measurement:
1. Please keep quiet for 5-10 minutes, and avoid eating, drinking clcohol, smoking, exercising and bathing before taking measurement. All these factors will influence the measurement result.
2. Remove any garment the fits closely to your upper arm.
3. Always measure on the same arm (normally left).
4. Take measurement regularly at the same time of every day, as blood pressure changes even during the day.

Common factors of wrong measurement:
1. All efforts by the patient to support their arm can increase blood presure.
2. Make sure you are in a comfortable, relax position and do not activate any of the muscles in the measurement arm during measurement. Use a cushion for support if necessary.
3. If the arm artery lies lower or higher than the heart, a false reading will be obtained.

Note:
1. Only use clinically approved cuffs!
2. A loose cuff or a exposed bladder causes false reading.
3. With repeated measurements blood accumulates in the arm which can lead to false reading. Consecutive blood pressure measurements should be repeated after 5 minutes pause or after the arm has been held up in order to allow the accumulated blood to flow away.
