Fig. 7.  Computer simulation of how rapidly acetated Ringer's solution leaves the plasma to enter the interstital fluid space (V  ^t, light line ) or is excreted as urine (dark line ). The infusion is given at a rate of 50 ml/min during 30 min. Kinetic data derived from preeclamptic women (A , Ref. 19) and surgical patients (B , from the analysis made in fig. 3).
