Fig 1 Impact of ultrafiltration on delivered dose of HD measured by using spKt/V and URR. The curves are derived from formal single-pool modeling of urea kinetics assuming a 3-hour dialysis, no RKF, and a volume of urea distribution that is 58% of BW. ΔWt refers to net ultrafiltration losses as a fraction of final BW.

Fig 2 eKt/V as a function of dialysis treatment time. The rate equations for eKt/V (lower 3 lines) predict that dialysis efficiency decreases as time is shortened, creating a larger difference between eKt/V and spKt/V.

Fig 4 Stop-dialysate method for postdialysis blood sampling. Mean arterial and venous blood urea concentrations after stopping dialysate flow are expressed as a fraction of the blood urea concentration in the contralateral arm at time zero (n = 10). The data suggest that, for practical purposes, 3 minutes after stopping dialysate flow, equilibration has occurred between inlet and outlet blood.

Fig 5 Illustration of the “lag phenomenon.” The secondary decrease in blood pressure seen at 5 months unassociated with a change in ECV was observed in all 8 patients studied.

Fig 6 Effect of residual native kidney clearance (Kr). The increase in BUN levels from the post-BUN level to the next pre-BUN level is modulated by Kr, as shown in the lower curve. The result is a pre-BUN level that is lower when compared to the pre-BUN level in the absence of Kr (upper line).
