Wrap the cuff around your arm so it's snug but not too tight. As a rule of thumb, you should be able to slip one finger under the cuff. Place the cuff against your skin, not over your clothing. The bottom of the cuff should be about one inch above the bend, or crease, in your elbow.
Accordingly, what is the right size blood pressure cuff?
CUFF SIZE AND PLACEMENT. The most common error in blood pressure measurement is use of inappropriate cuff size. Considerable overestimation can occur if the cuff is too small. The bladder length recommended by the AHA is 80 percent of the patient's arm circumference, and the ideal width is at least 40 percent.
How do you know what size blood pressure cuff to use?
Read the measurement on the tape measure in inches. A circumference of 7 to 9 inches requires a small adult sized cuff. A regular, or standard sized cuff, is needed if the arm circumference measures 9 to 13 inches. A large adult cuff should be used if the measurement is 13 to 17 inches.
