Heparin Infusion Rate Calculator
Calculate bolus and infusion rates for Unfractionated Heparin. Designed for emergency use with weight caps and high-contrast visuals.
About
Unfractionated Heparin requires weight-based dosing to achieve therapeutic anticoagulation rapidly without causing hemorrhage. This calculator is designed for high-stress environments like the Emergency Room, providing clear Bolus and Infusion rates based on the indication (ACS/NSTEMI vs. DVT/PE). It enforces safety limits by capping the weight used for calculation (typically max 100 kg for bolus calculations) to prevent massive overdoses in obese patients, adhering to standard ACCP and hospital-specific nomograms.
Formulas
Calculations follow standard weight-based protocols:
Safety Rule: If Actual Weight > Max Cap (100kg), use Max Cap for calculation.
Reference Data
| Indication | Initial Bolus | Initial Infusion | Max Bolus Cap |
|---|---|---|---|
| DVT / PE | 80 units/kg | 18 units/kg/hr | 5,000 units (usually) |
| ACS / NSTEMI | 60 units/kg | 12 units/kg/hr | 4,000 units |
| Stroke / Neuro | Usually None | 10-12 units/kg/hr | N/A |
