WebThe pediatric GFR calculator is for use in children under 18 years old. For persons 18 and older, use the GFR calculator for adults.; If values for cystatin C and/or BUN are not entered, the calculator will generate GFR estimates using the creatinine-based “Bedside Schwartz” equation only (currently considered the best method for estimating GFR in children). WebSep 12, 2011 · Dialysis clearance equation. K versus QB for QD = 1,000, 500, 400 [KoA = 1,000]. At lower QBs, the clearance (K) is linear with QD, but as QB increases closer to QD, there is a diminishing benefit of increasing QB further (as QD becomes clearance limiting). Many insights can be obtained by an analysis of the clearance equation. ...
