Calculation Formula

Infusion Rate (mL/hour) = Volume (mL) / Infusion Time (hours)

Where:
Volume (mL): Total volume of fluid to be infused
Infusion Time (hours): Time over which to administer the infusion

Infusion Rate Calculator Calculator Usage Guide

Learn how to use the Infusion Rate Calculator and its working principles

How to Use the Calculator

  1. Enter the total volume of the infusion (mL) to be administered
  2. Enter the infusion time in hours
  3. Optionally, enter the drip rate (gtt/mL) if you know it
  4. Optionally, enter the drug concentration (mg/mL) and desired dose (mg/hour) for medication calculations
  5. Click the "Calculate" button to determine the infusion rate

Formula Used

The calculator uses the formula: Infusion Rate (mL/hour) = Volume (mL) / Infusion Time (hours)

When to Use

This calculator is useful for healthcare professionals who need to determine the correct infusion rate for IV medications and fluids. It helps ensure accurate administration of treatments by providing the appropriate mL/hour rate.

Example Scenario

You need to administer 1000 mL of D5W over 8 hours. The IV tubing has a drip factor of 15 gtt/mL. The calculation would be:
Infusion Rate = 1000 mL / 8 hours = 125 mL/hour
GTT Rate = 15 gtt/mL × 125 mL/hour = 1875 gtt/hour = 31.25 gtt/min
