Calculation Formulas (Reference)

Protein (g) = Total Kcal × Protein% / 4 kcal/g

Dextrose (g) = Total Kcal × Dextrose% / 3.4 kcal/g

Lipid (g) = Total Kcal × Lipid% / 9 kcal/g

AA Volume (mL) = Protein (g) / (AA Concentration% / 100)

Dextrose Volume (mL) = Dextrose (g) / (Dex Concentration% / 100)

Lipid Volume (mL) = Lipid (g) / (Lipid Concentration% / 100)

Infusion Rate (mL/hr) = Volume / Infusion Hours

GIR (mg/kg/min) = Dextrose(g) × 1000 / (Weight(kg) × 1440)
