WebbAs CO (or venous return) increases, CVP decreases and more blood is pumped from veins to the right atrium. Consequently, increases in MSFP or decreases in RAP lead to increased venous return. Venous return increases as the pressure difference between RAP … WebbLeft ventricular stroke volume also falls because of reduced pulmonary venous return (decreased left ventricular preload). This causes cardiac output (CO) and mean arterial pressure (MAP) to fall. If arterial pressure falls appreciably upon standing, this is termed orthostatic or postural hypotension.
