Heparin Infusion Dose Calculator
Weight-based heparin dosing for VTE treatment. Calculates loading dose and initial infusion rate based on patient weight, per standard weight-based protocol.
Score interpretation
Heparin Initial Dose (units) ≥ 0
VTE: result is the bolus; then 18 U/kg/h. ACS: result is the bolus; then 12 U/kg/h (max 1,000 U/h). Prophylaxis: result is the SC dose (5,000 U every 8–12 h, no bolus).
→ Adjust to aPTT or anti-Xa per local protocol; monitor platelets for HIT.
Interpretation bands for the Heparin Dosing. Apply clinical judgement and local guidance.
