Which Arm Is More Accurate For Taking Blood Pressure?

(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.

Why is blood pressure different in each arm?

A large difference in systolic blood pressure between arms – defined as ≥ 10 mm Hg – may be a sign of increased cardiovascular disease – and even the threat of death. That is because when blood pressure is higher in one arm, it may be because of narrowing in a blood vessel, called “artery”, in that arm.

Why is blood pressure higher on right arm?

Big arm-to-arm difference in blood pressure linked to higher heart attack risk. Small differences in blood pressure readings between the right and left arm are normal. But large ones suggest the presence of artery-clogging plaque in the vessel that supplies blood to the arm with higher blood pressure.

Does arm position affect blood pressure reading?

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).

How can I get an accurate blood pressure reading?
