Units/Hr to ML/Hr Formula:
| From: | To: |
The Units/Hr to ML/Hr conversion calculates the infusion rate in milliliters per hour based on the prescribed units per hour and medication concentration. This is essential for accurate medication administration, particularly for IV infusions.
The calculator uses the formula:
Where:
Explanation: This simple division converts the prescribed units-based dosing to the corresponding volume-based infusion rate needed for pump programming.
Details: Accurate conversion is critical for safe medication administration, particularly for high-alert medications like heparin, insulin, and other titratable IV drugs where precise dosing is essential.
Tips: Enter the prescribed units per hour and the medication concentration (units/mL). Both values must be positive numbers. The calculator will provide the corresponding mL/hr infusion rate.
Q1: Why is this conversion important in healthcare?
A: Many IV medications are prescribed in units/hr but administered using infusion pumps programmed in mL/hr, making this conversion essential for accurate medication delivery.
Q2: What medications commonly require this calculation?
A: Heparin, insulin, various inotropes (like dobutamine), and vasoactive medications often require units/hr to mL/hr conversions.
Q3: How do I determine the concentration?
A: Concentration is typically determined by pharmacy preparation or standard protocols. It represents how many units of medication are contained in each milliliter of solution.
Q4: Are there safety checks I should perform?
A: Always double-check your calculations, verify concentration with pharmacy if uncertain, and have a second clinician independently verify critical medication calculations.
Q5: What if my calculation results in a very small number?
A: For very low infusion rates, consider using a more concentrated solution or a dedicated pump capable of precise micro-infusions to ensure accuracy.
