Fig. 1 Mean peak femoral venous velocity as a function of mean maximal corrected femoral vein diameter (actual diameter/body surface area) (BSA). r = −0.99.

Fig. 2 Femoral vein flow patterns at −10 degrees displayed simultaneously with the cardiac (A) and respiratory (B) cycles. In this position flow depended much more on the cardiac than the respiratory cycle.
