Document Summary

The force exerted by the blood against the inside of the blood vessels. The main driving force propelling blood to the tissues. Although such force occurs throughout the vascular system, the term blood pressure refers to the arterial pressure in branches of the aorta. Blood pressure rises and falls in a pattern corresponding ot the phases pf the cardiac cycle: systolic pressure- the maximum pressure achieved furing ventricular contraction (ventricular systole, diastolic pressure, pulse pressure. Mean arterial pressure: the average arterial pressure during a cardiac cycle, calculating mean arterial pressure, map = diastolic pressure + 1/3 pulse pressure, map = (systolic pressure/3) + (2 x diastolic pressure/3) Or: example, systolic pressure = 120mmhg, diastolic pressure = 80mmhg, pulse pressure = 40mmhg, map = diastolic pressure + 1/3 pulse pressure, = 80 + (0. 33 x 40, = 80 + 13. 33, =93. 33mmhg.
