Variables used for calculating nPCR

Variable	Definition
G (mg/min)	[(C2 × V2) – (C1 × V1)]/T
C1	Postdialysis BUN (mg/dL)
C2	Predialysis BUN (mg/dL)
V1 (for G calculations)	Postdialysis total body water (dL)
V2	Predialysis total body water (dL)
T	Time from the end of dialysis treatment to the beginning of the next treatment in minutes
V1 (for nPCR calculations)	Total body water (L)
Volume calculations for V values	5.8 dL/kg and pre- or postdialysis weight in kg; for V1 in nPCR calculations: 0.58 and weight in kg
