1. What is an IV Flow Rate Calculator mL/hr?

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

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q_{ml} \) — Flow rate (mL/hour)
• \( V_d \) — Total volume to be infused (mL)
• \( t \) — Infusion time (hours)

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

3. Importance of IV Flow Rate Calculation

Details: Accurate flow rate calculation ensures proper medication administration, prevents fluid overload, and maintains therapeutic effectiveness.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Can I use this for pediatric patients?
A: Yes, but always verify calculations and consider using an infusion pump for precise delivery.

Q2: How do I calculate for minutes instead of hours?
A: Convert minutes to hours (divide by 60) before entering the value.

Q3: What's a typical flow rate range?
A: Normal ranges vary by treatment but typically 20-100 mL/hr for maintenance fluids.

Q4: Does this account for drop factors?
A: No, this calculates mL/hr only. For drops/min, you'll need additional calculations.

Q5: How precise should my measurements be?
A: For critical medications, measure to the nearest 1 mL; for maintenance fluids, rounding to 5-10 mL is often acceptable.
