Frequently asked questions
Packed red cell transfusion volume: What does this calculator compute?
Calculates the red cell concentrate volume for a desired hemoglobin increase in children using three rules: BSH 2016 ((target − actual in g/l) × kg × factor / 10, factor 4 recommended), Davies 2007 (kg × increase in g/dl × 3 / hematocrit of the concentrate) and German Medical Association 2020 (3 ml/kg per 1 g/dl).
