TPN Osmolality Estimator (Peripheral/Central)
Estimate the osmolality (mOsm/L) of a parenteral nutrition admixture to help choose peripheral vs central access. Sum-of-solute formula: Osm ≈ Dextrose(g/L)×5 + AA(g/L)×10 + Electrolytes. Thresholds: ≤ 900 peripheral; 900–1200 caution; > 1200 central. Lab-measured value is the gold standard. Derived from Mirtallo 2004, Pittiruti 2009, Dugan 2014. Not medical advice.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/tpn-osmolality-estimator' \
-H 'Content-Type: application/json' \
-d '{"dextrosePercent":10,"dextroseVolume":1000,"aaPercent":5,"aaVolume":500,"lipidVolume":250,"electrolyteOsm":350,"decimalPlaces":0}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
