1. What is the Infusion Rate Formula?

The infusion rate formula calculates the flow rate of intravenous fluids in milliliters per hour (mL/hr). It is fundamental in medical settings for proper medication and fluid administration.

2. How Does the Calculator Work?

The calculator uses the infusion rate equation:

Where:

• Volume — Total amount of fluid to be infused (in milliliters)
• Time — Duration over which the fluid should be infused (in hours)

Explanation: The equation divides the total volume by the total time to determine the hourly infusion rate.

3. Importance of Infusion Rate Calculation

Details: Accurate infusion rate calculation ensures patients receive medications and fluids at the correct dosage and speed, preventing complications from too rapid or too slow administration.

4. Using the Calculator

Tips: Enter volume in mL and time in hours. Both values must be positive numbers. For minutes, convert to hours (e.g., 30 minutes = 0.5 hours).

5. Frequently Asked Questions (FAQ)

Q1: How do I calculate for minutes instead of hours?
A: Convert minutes to hours by dividing by 60 (e.g., 120 minutes = 2 hours).

Q2: What are typical infusion rates?
A: Rates vary by medication and patient condition. Common ranges are 20-125 mL/hr for maintenance fluids, but always follow specific orders.

Q3: How does this relate to drip rates?
A: To get drops/minute, multiply mL/hr by the drip factor (gtts/mL) and divide by 60.

Q4: When would I use this calculation?
A: For IV fluid administration, medication infusions, blood transfusions, and parenteral nutrition.

Q5: What if my infusion runs over multiple days?
A: Convert days to hours (1 day = 24 hours) or calculate rate per hour as shown.
