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 a force occurs throughout the vascular system, the term blood pressure refers to arterial pressure in branches of the aorta. Blood pressure rises and falls in a pattern corresponding to the phases of the cardiac cycle. Systolic pressure the maximum pressure achieved during ventricular contraction (systole), pressure rises. Diastolic pressure- the lowest pressure achieved during ventricular relaxation (diastole), pressure drops, diastole lasts longer. Pulse pressure- the difference between systolic and diastolic pressures. The average arterial pressure during a cardiac cycle. Therefore: increase in sv causes increase in map and decrease in sv causes decrease in. Therefore: increase in hr causes increase in map and decrease in hr causes decrease in. Mean arterial pressure needs to be tightly regulated. Must be high enough to ensure sufficient driving pressure (sending blood to brain and other tissues)
