• Parenteral Nutrition Calculator

  Fluid, glucose, amino acids, lipids → composition, GIR, energy, osmolarity

• Glucose Infusion Rate (GIR)

  mg/kg/min from concentration and infusion rate – or vice versa

• PN Osmolarity

  Estimated osmolarity of a parenteral solution (Pereira-da-Silva 2004)

• Amino-Acid Intake

  g/kg/day from concentration and volume

• Lipid Intake

  g/kg/day from emulsion and volume

• Dextrose Intake

  Glucose intake g/kg/day and GIR

• Fluid intake volumes (D-A-CH guide values)

  Guideline values for beverages and total water intake by age, with classification of a daily amount

• Energy requirement (D-A-CH reference values)

  Guideline values for energy intake from infancy to adolescence by sex and PAL

• Basal metabolic rate by Schofield

  BMR from weight (and optionally height from 10 years of age) according to Schofield 1985 / FAO 2004 – with total energy expenditure by PAL

• Energy requirement according to FAO/WHO/UNU 2004

  Total energy expenditure from weight (infants linear, 1–18 years quadratic) plus growth – and comparison with the requirement per kg

• Energy intake in kcal/kg/day

  Actual intake per kg from food or infusion – compared with the requirement according to FAO 2004 and ESPGHAN (preterm infants)

• Protein intake in g/kg/day

  Actual protein intake per kg compared with the D-A-CH reference values by age

• Enteral volume for the energy requirement

  Required feed volume (ml/day, ml/kg/day, per meal) for a target energy from the energy density of the feed

• Feeding volume per meal

  Daily feeding volume from ml/kg (or Finkelstein rule in the first days of life) divided by the number of meals

• Caloric density and energy intake

  kcal/100 ml of a formula ↔ energy intake in kcal/kg/day at a given volume – EU limits for infant formula

• Breast milk fortification (fortifier)

  Energy and protein intake with BEBA FM 85 or Aptamil FMS (4 g/100 ml) for a given volume

• Nitrogen balance

  Intake (protein/6.25) minus losses – adult formula (+ 4 g) or pediatric formula in mg/kg (urea N × 1.25 + 75 mg/kg)

• Percentage weight loss

  Newborns: loss from birth weight with ABM thresholds (8–10 % from day 5); children 2–20 years: AND/ASPEN criteria (5 / 7.5 / 10 %)
