7.Attach the cuff: Hold the area of the cuff where the hose exits the cuff firmly against the inside of the bare upper arm directly over the brachial artery, and the bottom of the cuff approximately one inch (2-3cm) above the elbow, as shown in the third picture at right. Never place the cuff over clothing. Pull the opposite end of the cuff snugly around the arm and secure with the hook and loop fastener. The cuff should be snug, but not too tight. If one or two fingers can fit between the cuff and the arm, the cuff is properly secured. If you are unable to fit the cuff as described above, a smaller or larger cuff should be used.
