From: Mathematical models for phosphate kinetics in patients on maintenance hemodialysis

The profiles of free intracellular phosphate (P) and phosphate mass in intracellular store as well as the phosphate amount in the fast compartment during a one-week cycle of three hemodialysis (HD) sessions in a stable patient predicted by Models F, IC and F&IC. Shown are ion phosphate concentration (panel a) and mass (panel b) in intracellular space as well as ion phosphate amounts (panel c) in the fast compartments predicted by Models F (continuous lines), IC (dotted lines) and F&IC (hatched lines), see Tables 1 and 2 for the model parameters.
