1. What is the mg/hr to mL/hr Calculation?

The mg/hr to mL/hr calculation is essential for medication administration, particularly in intravenous therapy. It converts the prescribed medication dose (in mg per hour) to the corresponding infusion rate (in mL per hour) based on the medication concentration.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{mL/hr} = \frac{\text{mg/hr}}{\text{mg/mL}} \]

Where:

\( \text{mg/hr} \) — Prescribed medication rate in milligrams per hour
\( \text{mg/mL} \) — Medication concentration in milligrams per milliliter
\( \text{mL/hr} \) — Resulting infusion rate in milliliters per hour

Explanation: This calculation ensures the patient receives the correct dose of medication by adjusting the infusion pump rate based on the specific concentration of the medication solution.

3. Importance of Accurate Infusion Rates

Details: Precise calculation of infusion rates is critical for patient safety, especially with high-risk medications where small errors can lead to significant underdosing or overdosing.

4. Using the Calculator

Tips: Enter the prescribed medication rate in mg/hr and the medication concentration in mg/mL. Both values must be positive numbers. The calculator will compute the corresponding infusion rate in mL/hr.

5. Frequently Asked Questions (FAQ)

Q1: Why is this calculation important?
A: It ensures accurate medication delivery, particularly for critical care drugs where precise dosing is essential for therapeutic effect and patient safety.

Q2: What if my medication concentration changes?
A: You must recalculate the infusion rate whenever the medication concentration changes to maintain the correct dose.

Q3: How should I verify my calculations?
A: Always double-check calculations and have them verified by another healthcare professional when possible, especially for high-risk medications.

Q4: Are there medications where this doesn't apply?
A: This applies to most continuous IV infusions. Some medications may use different units (e.g., units/hr) but the same principle applies.

Q5: What about weight-based dosing?
A: For weight-based medications, first calculate the mg/hr dose based on patient weight, then use this calculator to determine the mL/hr rate.
