Heparin Drip Formula:
| From: | To: |
Heparin drip calculation determines the appropriate infusion rate for intravenous heparin administration based on patient weight, desired dose, and medication concentration. This calculation is critical for safe and effective anticoagulation therapy.
The calculator uses the heparin drip formula:
Where:
Explanation: The formula calculates the milliliter per hour infusion rate needed to deliver the prescribed heparin dose based on the patient's weight and the concentration of the heparin solution.
Details: Accurate heparin dosing is essential for effective anticoagulation while minimizing bleeding risks. Weight-based dosing ensures personalized treatment, and precise infusion rates maintain therapeutic heparin levels.
Tips: Enter the desired heparin dose in units/kg/hr, patient weight in kilograms, and heparin concentration in units/mL. All values must be positive numbers for accurate calculation.
Q1: What is the typical heparin dosing range?
A: Heparin infusion typically ranges from 12-18 units/kg/hr for most indications, though specific protocols may vary.
Q2: How often should heparin infusion rates be adjusted?
A: Rates should be adjusted based on regular monitoring of PTT (partial thromboplastin time) levels, typically every 6 hours until therapeutic levels are achieved.
Q3: What are common heparin concentrations?
A: Common concentrations include 25,000 units in 250 mL (100 units/mL) or 25,000 units in 500 mL (50 units/mL).
Q4: Why is weight-based dosing important for heparin?
A: Weight-based dosing individualizes therapy, improves efficacy, and reduces the risk of under or over-anticoagulation.
Q5: What safety checks should be performed?
A: Always double-check calculations, verify patient weight, confirm concentration, and use infusion pumps with appropriate safety limits.
