Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP), although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium. CVP and RAP can differ when arterial tone is alt… Web10 de set. de 2014 · The Hazards of a High Central Venous Pressure In addition to influencing venous return, a high CVP is transmitted retrograde, increasing venous pressure.
