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.

Frequently Asked Questions

To prevent bleeding risks in obese patients, this tool caps the calculation weight at 100 kg (or adheres to a strict max dose of 4000/5000 units depending on indication).
No. This calculator is strictly for Unfractionated Heparin (UFH) IV infusions.
This tool calculates the *Initial* starting rate. Subsequent rate adjustments should be based on aPTT or Anti-Xa levels drawn 6 hours after initiation.
