Positioning the Arm and Equipment
Use the left arm to take the reading. If using a wrist cuff, try to ensure the wrist is at the same height as the chest or you will get elevated or reduced readings. With the person sitting comfortably and their elbow resting on a surface, wrap the cuff around the upper arm until it feels snug. The cuff needs to be positioned about 2 cm above the elbow. Usually a Velcro strip makes this easy. The cord from the cuff should run down the inside of the arm straight to the machine. Make sure no kinks are in the cord.
