Right atrial pressure

Source: Wikipedia, the free encyclopedia.

Right atrial pressure (RAP) is the

blood returning to the heart and the ability of the heart to pump the blood into the arterial system. RAP is often nearly identical to central venous pressure (CVP),[1] 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 venous tone (i.e the degree of venous constriction) is altered. This can be graphically depicted as changes in the slope of the venous return
plotted against right atrial pressure (where central venous pressure increases, but right atrial pressure stays the same; VR = CVP − RAP).
