Before revision: The number of units that need to be removed to hemodilute to the maximum safe hematocrit (ANH) can be found by This is based on the assumption that each unit removed by hemodilution has a volume of 450 mL (the actual volume of a unit will vary somewhat since completion of collection ais dependent on weight and not volume).
