All formulas verified against source working notes and cross-checked against AHA/ACLS, WHO / Eddleston & Buckley (Lancet 2008), ACCP/ACC-AHA heparin nomograms, and GUSTO/AHA-STEMI references (July 2026). This tool assists calculation only — it does not replace clinical judgement, pharmacy verification, or your institution's approved protocol. Double-check every infusion rate before programming a pump.
