Erratum

Unfortunately, the original version of this article [1] contained an error. The legend to Fig. 6 is incorrect. It should read a “A decrease in capacitance is the same as lowering the opening on the side of a tub” instead of “increase”. Please find the correct figure legend below.

Fig. 6
figure 1

Change in cardiac output and venous return with an increase in capacitance. A decrease in capacitance is the same as lowering the opening on the side of a tub for it allows more volume to flow out, which is the equivalent of more volume being stressed. Graphically it results in a leftward shift of the volume–pressure relationship of the vasculature (upper left). This shifts the venous return curve to the right and increases cardiac output through the Starling mechanism (lower left). This effect is identical to giving volume to expand stressed volume.
