1. What is Infusion Flow Rate?

The infusion flow rate is the volume of fluid administered per unit time, typically measured in milliliters per hour (mL/hr). It's a critical parameter in intravenous therapy to ensure proper medication or fluid delivery.

2. How Does the Calculator Work?

The calculator uses the basic flow rate formula:

Where:

• Flow Rate — Measured in mL/hr
• Volume — Total volume to be infused (mL)
• Time — Duration of infusion (hours)

Explanation: This simple division gives the rate at which the IV fluid should be administered to complete the infusion in the specified time.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation ensures patients receive medications at the correct dosage, prevents fluid overload, and maintains therapeutic drug levels.

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 flow rate for minutes instead of hours?
A: First convert minutes to hours (divide by 60), or multiply the result by 60 to get mL/min.

Q2: What's a typical flow rate for IV fluids?
A: Maintenance rates are typically 50-100 mL/hr for adults, but this varies based on patient needs and medication.

Q3: How does this relate to drip rate?
A: Drip rate depends on flow rate and drop factor (drops/mL). Drip rate (gtts/min) = (Flow rate × Drop factor) / 60.

Q4: When would I need to calculate this manually?
A: When infusion pumps aren't available, when verifying pump settings, or during emergencies.

Q5: What factors might require adjusting the flow rate?
A: Patient condition, medication concentration, fluid restrictions, and specific clinical protocols.
