Patient Preparations of Measurement
Caution: Follow these steps to obtain reliable blood pressure reading. Lack of rest, incorrect
body posture, arm position, and improper cuff fitting may lead to inaccurate blood pressure reading!
Prior to Taking a Measurement
It is recommended that doctors perform double arm measurements on a patient’s first visit in
order to determine which arm to measure in the future. The arm with the higher blood pressure
should be measured.
Avoid exercising, bathing, eating, drinking, and smoking, 30 minutes prior to measurement.
Empty your bladder prior to measurement.
Sit down on a back-supported chair, keep the feet flat on the floor, and do not cross your legs.
Sit down on a Relax for at least 5 minutes before taking measurement.
Correct Cuff Fitting and Posture for Taking a Measurement
Make sure to use the correct cuff size suitable for patient’s arm circumference. Always measure
on the same arm (normally left).
Remove thick clothing and close-fitting garments from the upper arm. To avoid constriction,
shirt sleeves should not be rolled up - they do not interfere with the cuff if they are laid flat.
Fit the cuff snugly around the upper arm, with the lower edge positioned 1-2 cm above the
elbow, and the artery mark aligned with the (brachial) artery in the inner side of the arm. The
gaps between the cuff and the arm on both top and bottom edges of the cuff should be no
wider than two fingers width.
Support your arm on a desktop so it is relaxed. Make sure the middle of the cuff is at the same
height as your heart (right atrium).
