2. Figure 1
Flow chart of the two-pool kinetic model. V1, perfused volume; V2, nonperfused volume; Vtot, total distribution volume; C1, concentration in perfused compartment; C2, concentration in nonperfused compartment; CPi, plasma concentration at blood inlet; CPo, plasma concentration at blood outlet; CDi, concentration at dialysate inlet; CDo, concentration at dialysate outlet; K, dialyzer clearance; K12, intercompartmental clearance; GS, solute generation rate; QB, dialyzer blood flow; QD, dialyzer dialysate flow; QUF, ultrafiltration flow.

3. Figure 2
Concentration profiles (mmol/L) during the dialysis session of urea and the different investigated guanidino compounds in a representative patient. The asterisks (*) plot the measured data, while the thin and bold line represents the fitted concentration profiles in the perfused (V1) and nonperfused compartment (V2), respectively. The angle in between the dotted lines is a measure for the solute removed from the nonperfused compartment (delta SC2eff).
