1. What is IV Infusion Rate?

The IV infusion rate is the speed at which intravenous fluids are administered to a patient, typically measured in milliliters per hour (mL/hr). It's crucial for ensuring proper medication delivery and fluid balance.

2. How Does the Calculator Work?

The calculator uses the basic infusion rate formula:

Where:

• \( \text{Rate} \) — Infusion rate (mL/hr)
• \( \text{Volume} \) — Total volume to be infused (mL)
• \( \text{Time} \) — Total infusion time (hours)

Explanation: This simple calculation divides the total volume by the total time to determine the continuous infusion rate.

3. Importance of Infusion Rate Calculation

Details: Accurate infusion rates are essential for medication safety, especially with time-sensitive or potent drugs. Incorrect rates can lead to underdosing or toxicity.

4. Using the Calculator

Tips: Enter the total volume in milliliters and the desired infusion time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate drops per minute?
A: First calculate mL/hr, then multiply by the drop factor (gtts/mL) and divide by 60. Example: (mL/hr × gtts/mL) ÷ 60 = gtts/min.

Q2: What's a typical infusion rate?
A: Rates vary widely depending on the therapy. Maintenance fluids might be 50-100 mL/hr, while specific medications may require precise rates.

Q3: How does this differ from drip rate?
A: Infusion rate is in mL/hr while drip rate is in drops per minute. The drip rate depends on the infusion set's drop factor.

Q4: When would I need to adjust the rate?
A: Rates may need adjustment based on patient response, fluid status, or lab values. Always follow prescribed protocols.

Q5: Are there limitations to this calculation?
A: This is for simple continuous infusions. Complex regimens like intermittent or titrated infusions require additional calculations.
