Infusion Speed Calculator

Calculate the infusion rate for IV fluids to ensure proper administration based on patient weight, volume, and desired time.

Input Parameters

Infusion Rate (mL/hour)

--

Calculation Formula

mL/hour = Volume (mL) / (Duration (hours) × Patient Weight (kg))

Where:
Volume (mL): Total volume of fluid to be infused
Duration (hours): Time over which to infuse
Patient Weight (kg): Weight of the patient receiving the infusion

Safety Recommendations

  • Maximum infusion rate for adults: 3 mL/kg/hour for normal saline
  • Maximum infusion rate for dextrose solutions: 0.5 mL/kg/hour per gram of dextrose
  • Always consult with a healthcare professional before starting any IV infusion

Infusion Speed Calculator Usage Guide

Learn how to use the Infusion Speed Calculator and understand its importance in medical care

How to Use the Infusion Speed Calculator

  1. Enter the total volume of fluid to be infused in milliliters (mL)
  2. Input the patient's weight in kilograms (kg)
  3. Specify the duration of the infusion in hours
  4. Select the type of fluid being infused from the dropdown menu
  5. Click the "Calculate" button to determine the infusion rate

Understanding Infusion Rate

The infusion rate is measured in milliliters per hour (mL/hour) and represents how quickly IV fluids should be administered. This is calculated by dividing the total volume of fluid by the infusion duration in hours.

Important Considerations

  • Always double-check calculations before starting an IV infusion
  • Consider the patient's medical condition and any specific fluid restrictions
  • Monitor patients receiving IV infusions for any adverse reactions
  • Adjust infusion rates as needed based on patient response and clinical judgment

Practical Example

For a patient weighing 70 kg who needs to receive 1000 mL of normal saline over 8 hours:

Input: Volume = 1000 mL, Weight = 70 kg, Hours = 8, Fluid Type = Normal Saline

Calculation: 1000 mL / (70 kg × 8 hours) = 17.86 mL/hour

Result: The infusion rate should be set to approximately 17.86 mL/hour
