1. What is IV Flow Rate Calculation?

Definition: This calculator determines the intravenous (IV) flow rate in milliliters per hour based on the total volume to be infused and the time period.

Purpose: It helps medical professionals and caregivers accurately administer IV fluids over a specified time period.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{mL} \) — Flow rate (milliliters per hour)
• \( V_d \) — Volume to be infused (milliliters)
• \( t \) — Time (hours)

Explanation: The total volume is divided by the infusion time to determine the required flow rate.

3. Importance of Accurate IV Flow Rate

Details: Proper flow rate calculation ensures patient safety, prevents fluid overload, and guarantees therapeutic effectiveness.

4. Using the Calculator

Tips: Enter the total volume to be infused in mL and the desired infusion time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert minutes to hours?
A: Divide minutes by 60 (e.g., 30 minutes = 0.5 hours).

Q2: What's a typical flow rate range?
A: Common rates vary from 20-125 mL/h for adults, but always follow specific orders.

Q3: How does this relate to drip rate?
A: Flow rate (mL/h) can be converted to drops/min using the drip factor (gtts/mL).

Q4: What if my infusion time is in days?
A: Convert days to hours (1 day = 24 hours) before calculation.

Q5: How do I account for IV tubing volume?
A: Priming volume is typically negligible but can be added to V_d if needed.
