Introduction
Blood pressure (BP) is the force exerted by moving blood against blood vessel walls. The heart's action of pumping blood through the circulatory system is mostly responsible for this pressure. The pressure in the major arteries is meant when the word "blood pressure" is used without qualification. Systolic pressure, or the highest pressure during one heartbeat, is typically stated as the ratio of diastolic pressure, or the lowest pressure between two heartbeats, in blood pressure measurements. It is expressed as a millimetre of mercury (mmHg) above the air pressure in the immediate vicinity.
