Figure 2From: Clinical review: Guyton - the role of mean circulatory filling pressure and right atrial pressure in controlling cardiac outputCardiac function curves can be superimposed on venous return curves. Cardiac function curves (green, blue, and red lines) depict the heart function under different conditions. Venous return curves (grey lines) represent normal, decreased, and increased values of mean circulatory filling pressure (MCFP). Redrawn and modified from Guyton [30].Back to article page
