Flow Fraction (FF) = dialysate flow rate/blood flow rate (Q d /Q b ). As a result, the lower the Q d is, the lower the FF and the more saturated the dialysate will be. FF prescribed tend to range from 0.2 to 0.5. At a FF of 0.2 for example, dialysate saturations of urea and creatinine are approximately 95% and 90%, respectively.
