Overview

This calculator generates a step-by-step enteral feeding advancement schedule for NICU infants. Enter the infant’s weight, current feed volume, frequency, advancement rate, and goal volume to produce a projected schedule with estimated time to goal.

How It Works

The schedule is built by incrementally advancing the feed volume by the specified amount at each interval, until the goal volume is reached. All volumes are calculated based on the infant’s weight at the time of entry — recalculate when weight changes significantly. Goal feed volume is rounded to the nearest 0.5 mL (bolus) or 0.1 mL/hr (cont). Feed volumes in schedule are rounded to the nearest mL (bolus) or 0.1 mL/hr (cont). Time to goal is rounded to the nearest 0.25 days. IV wean rate it rounded to 2 decimal places.

Trophic Feeds

Trophic feeds are defined as enteral intakes of 10–20 mL/kg/day. These volumes are considered non-nutritive and are used primarily to prime the gut rather than meet nutritional requirements.

120 mL/kg/day Threshold

The green-highlighted row in the schedule marks the step at which enteral intake reaches 120 mL/kg/day. Many NICUs use this as a threshold for discontinuing or weaning IV fluids, though institutional protocols vary.

IV Wean Suggestion

For bolus feeding schedules, the calculator provides an IV/PN wean rate suggestion based on the advancement volume. This is a mathematical estimate only and must be verified against the infant’s clinical status and total fluid goals.

Important Notes

Feeding advancement rates should be individualized based on clinical tolerance, diagnosis, and institutional protocol. This calculator does not account for feed intolerance, clinical deterioration, or changes in weight. It is intended as a clinical support tool for registered dietitians and other healthcare professionals and does not replace clinical judgment.
