Infusion Rate Calculator (ml/min)
Calculate medical fluid delivery speed accurately
Calculated Infusion Rate:
0.00 ml/min
Understanding Infusion Rate Calculation
An infusion rate calculator is a critical tool used in healthcare settings to determine the precise speed at which fluid (such as saline, medication, or blood) should be administered to a patient. While many pumps are set in ml/hr, calculating the ml/min rate is often necessary for rapid infusions, emergency medicine, or specific pediatric protocols.
The Formula
Rate (ml/min) = Total Volume (ml) ÷ Total Time (minutes)
How to Use This Calculator
- Total Volume: Enter the total amount of fluid in milliliters (ml) to be infused.
- Duration: Enter the time in hours and/or minutes. If the infusion is only 30 minutes, leave the hours field blank or enter 0.
- Calculate: Click the button to see the milliliters per minute required.
Practical Example
If a physician orders 1,000 ml of Normal Saline to be infused over 4 hours:
- Total Minutes = 4 hours × 60 = 240 minutes.
- 1,000 ml ÷ 240 minutes = 4.17 ml/min.
