A weight-based heparin dosing calculator for pharmacists, nurses and physicians managing intravenous heparin infusions. Enter weight, height and biological sex to get ideal body weight, the actual-to-ideal ratio and the dosing weight your protocol calls for. Select one or more protocols to see the bolus and initial infusion rate for standard DVT/PE, low-dose, intra-aortic balloon pump, neurosurgery, ECMO/Impella and LVAD anticoagulation. Each protocol includes its aPTT and anti-Xa titration table so rate adjustments can be read off at the bedside. Runs entirely in the browser; no patient data leaves the device.
