Figure 4. Representative graphic output of the volume kinetic analysis in one male volunteer in whom the blood hemoglobin (B-hemoglobin; upper), blood water (B-water; middle), and serum albumin (S-albumin; lower) concentrations were used as markers of dilution during and after an intravenous infusion of Ringer solution. The measured dilution (circles) and the model predicted dilution-time curve for the primary fluid space (upper line during infusion) and the secondary fluid space are shown.
