Blood Pressure

Blood pressure is the force exerted by blood against the wall of a blood vessel. It is commonly measured in a large artery with an inflatable cuff known as a blood pressure cuff or blood pressure apparatus, but technically called a sphygmomanometer. Both systolic and diastolic pressures are measured and reported as systolic then diastolic separated by a slash, such as 120/80. Pressure is expressed as millimeters of mercury (mm Hg), that is, the height to which the pressure can push a column of mercury in a tube. Blood pressure is a valuable diagnostic measurement that is easily obtained.
