Enteral feeds

Feeds per day: 8 (q3h, fixed)

Rounding: feed volume to nearest whole mL; total enteral to whole mL/kg/day.

Infusions

Enter up to 4 infusions. Leave unused rows blank.

GIR per drip = (Dextrose % × Rate mL/h) ÷ (6 × Weight kg); overall GIR is the sum. Total fluid intake = (Σ rates × 24) ÷ Weight. GIR rounded to 1 decimal, TFI to whole mL/kg/day.
