Arterial blood pressure

The highest arterial blood pressure occurs during the heart’s systole. It is called arterial systolic pressure. The minimum arterial blood pressure occurs during the heart’s diastole and is called arterial diastolic pressure. The difference between systolic and diastolic pressure is called pulse pressure. In central arteries at rest, it is about 40 mm Hg. Pulse pressure is directly proportional to the heart’s systolic volume. Normally, arterial systolic blood pressure is 120 mm Hg, and diastolic is about 80 mm Hg. Arterial mean blood pressure is the average of arterial blood pressure during the cardiac cycle, which describes the blood-pushing force.

It is noteworthy that arterial mean blood pressure is directly proportional to the minute heart volume and total peripheral resistance.
