Therapy Fluid Conservation Nomogram. For a given patient weight and prescribed dose, a total therapy fluid volume required session was calculated and rounded up to a 5-L increment (5-L therapy fluid bags). Flow rates for patients on this sharing protocol were determined by adjusting for a 22-hour period. The projected total delivered therapy volume for a standard 48-hour period was adjusted for a 22-hour delivery period (standard flow rates multiplied by 2.18 [$48\text{hours}/22\text{hours}=2.18$]) and rounding down to the nearest dl/h. This prevented partially used therapy fluid bags from being discarded at the end of a 22-hour treatment session.
