Question

How is blood pressure measured using sphygmomanometer?

Answer 1

Blood pressure is always measured in the upper arm artery using sphygmomanometer. There are two pressure readings. One measures the strongest pressure during the time blood is forced out of the ventricles. This is called systolic pressure. For a healthy young adult it will be 120 mm of Hg. The second reading is taken during the resting period, as the ventricles refill with blood. This is called diastolic pressure. It will be 80 mm of Hg.
