How do you position a blood pressure cuff?
The artery mark indicates proper cuff positioning. Place the cuff over the bare upper arm with the artery mark positioned directly over the brachial artery. The bottom edge of the cuff should be positioned approximately one inch (2-3 cm) above the antecubital fold.
Blood Pressure Cuff is too Small1,3,4 - It is extremely important to make sure the proper size blood pressure cuff is used on your upper arm when taking a measurement. Studies have shown that using too small of a blood pressure cuff can cause a patient's systolic blood pressure measurement to increase 10 to 40 mmHg.
- The patient should sit or lie comfortably. The arm should be fully supported on a flat surface at heart level. (If the arm's position varies, or is not level with the heart, measurement values obtained will not be consistent with the patient's true blood pressure).
- However, the American Heart Association recommends using a home blood pressure monitor that measures blood pressure in your upper arm and not using wrist or finger blood pressure monitors. Even then, blood pressure measurements taken at the wrist are usually higher and less accurate than those taken at your upper arm.
- As your body goes through different changes, whether it's stress or intense exercise, the diastolic blood pressure will change to meet your muscles' oxygen demand. Other factors that affect diastolic blood pressure include: body position, diet, weight loss, smoking and alcohol use and poor sleeping habits.
(It's best to take blood pressure from the left arm, if possible.) Rest in a chair next to a table for five to 10 minutes. (Your left arm should rest comfortably at heart level.) Sit up straight with your back against the chair, legs uncrossed.
- Follow a healthy lifestyle to keep it at this level. More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it. Make healthy changes to your lifestyle.

- Answer: The blood pressure measured at the calf would be larger than that measured at the arm. The blood at the calf is deeper in the liquid than that at the arm and so it is is at higher pressure. Blood pressures are normally taken at the arm because it is at approximately the same height as the heart.
