1. What is Mcg/kg/hr to Ml/hr Conversion?

This calculator converts medication doses from micrograms per kilogram per hour (mcg/kg/hr) to milliliters per hour (mL/hr) based on the drug concentration (mg/mL). This is commonly used for IV infusions in critical care settings.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ mL/hr = \frac{(mcg/kg/hr \times weight \times 60)}{(concentration \times 1000)} \]

Where:

\( mcg/kg/hr \) — Medication dose in micrograms per kilogram per hour
\( weight \) — Patient's weight in kilograms
\( concentration \) — Drug concentration in mg/mL
60 — Conversion factor for hours to minutes
1000 — Conversion factor for micrograms to milligrams

Explanation: The equation converts the weight-based dose to an actual infusion rate based on the specific concentration of the medication being administered.

3. Importance of Accurate Conversion

Details: Precise conversion is critical for safe medication administration, especially for potent drugs like vasoactive medications, sedatives, and inotropes where small dosing errors can have significant clinical consequences.

4. Using the Calculator

Tips: Enter the prescribed dose in mcg/kg/hr, patient's weight in kg, and medication concentration in mg/mL. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is this conversion necessary?
A: Medications are often prescribed by weight (mcg/kg/hr) but administered via infusion pumps programmed in mL/hr, requiring this conversion.

Q2: What's the difference between mg and mcg?
A: 1 milligram (mg) = 1000 micrograms (mcg). This conversion is built into the formula.

Q3: How often should I verify my calculations?
A: Always double-check calculations, especially when starting new infusions or changing rates. Many institutions require independent verification for high-risk medications.

Q4: Does this work for all medications?
A: This works for any medication where the dose is prescribed in mcg/kg/hr and the concentration is known in mg/mL.

Q5: What if my concentration is in mcg/mL?
A: If your concentration is in mcg/mL, remove the 1000 from the denominator of the formula (since you wouldn't need to convert from mcg to mg).
