Enteral Nutrition Target Calculator (kcal/kg + Protein g/kg)
Compute daily kcal and protein targets for enterally fed adults from weight, kcal/kg and g/kg prescriptions, then translate them into product volume and starting rate. Targets from ASPEN/SCCM, ESPEN. Caveats: actual vs ideal weight, trophic feeding, gastric residual, aspiration precautions. Derived from McClave 2016, Singer/ESPEN 2019, Boullata 2017, MDCalc. Not medical advice.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/enteral-nutrition-target' \
-H 'Content-Type: application/json' \
-d '{"weight":70,"weightBasis":"actual","kcalPerKg":25,"proteinPerKg":1.2,"formulaKcalPerMl":"1","formulaProteinPerL":40,"decimalPlaces":1}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
Endpoint
POST https://api.elysiatools.com/en/api/tools/enteral-nutrition-targetParameters
| Name | Type | Required | Description |
|---|---|---|---|
| weight | number | Yes | Body weight (kg). Use actual body weight unless the patient is obese (>120% ideal) or significantly fluid-overloaded — then use ideal or adjusted weight and record the choice. |
| weightBasis | select | Yes | — |
| kcalPerKg | number | Yes | Prescribed energy target in kcal/kg/day. Typical: 20–30 maintenance, 12–18 early critical illness, 30–35 major burns/trauma. |
| proteinPerKg | number | Yes | Prescribed protein target in g/kg/day. Typical: 0.8–1.0 maintenance, 1.0–1.5 acute illness, up to 2.0 critically ill, 1.5–2.5 burns. |
