Partial-exchange volume from Kumar 2004: volume_ml = (actual_hct_percent - 55) / actual_hct_percent * blood_volume_ml. Desired hematocrit is the trial's 55 percent only. Caller assigns blood volume; magent does not choose millilitres per kilogram or saline versus plasma. Not a transfusion order or indication (the trial found no long-term benefit in asymptomatic LBW). Deterministic published arithmetic with citation.Overview
