Fig. 4. Measured (  symbols ) and predicted (  lines ) data for a single animal (#152). All data were analyzed simultaneously. The three upper datasets refer to dilution of the central compartment measured by dilution of plasma (  left axis ). The three lower datasets refer to urinary output (  right axis ). Three experimental sessions are depicted: infusion of 0.9% saline 25 ml/kg in 20 min (  open circles, bold broken lines ), hemorrhage of 300 ml (7.5 ml/kg) in 5 min (  open triangles, dotted lines ), and the combined experiment with hemorrhage 300 ml followed by infusion (  filled squares, black lines ).
