Mean systemic pressure

Mean systemic pressure increases if there is an increase in blood volume or if there is a decrease in venous compliance (where blood is shifted from the veins to the arteries). An increase in mean systemic pressure is reflected in a shift of the vascular function curve to the right. Mean systemic

MSP is measured in two ways experimentally, and as a result has two alternative naming conventions. MSFP is measured after clamping the aortic root and the great veins at point of entry to right atrium. On the other hand, MCFP is measured experimentally by briefly inducing

pressure is decreased by a decrease in blood volume or by an increase in venous compliance (where blood is shifted from the arteries to the veins). A decrease in mean systemic pressure is reflected in a shift of the vascular function curve to the left.
