Infusion Rate Calculator
Infusion Rate:
— mL/hr
Calculating Infusion Rates
This calculator helps you determine the correct infusion rate for administering medications or fluids. It's crucial for healthcare professionals to accurately calculate these rates to ensure patient safety and therapeutic effectiveness. Incorrect infusion rates can lead to underdosing (reducing efficacy) or overdosing (causing adverse effects).
The calculation depends on the total volume of the solution to be infused, the desired duration of the infusion, and the delivery rate of the infusion device. We will use the following formula:
**Infusion Rate = Total Volume / Total Time**
However, infusion pumps often require the rate to be set in milliliters per hour (mL/hr). If your total time is given in minutes, you'll need to convert it to hours.
Let's break down the inputs:
* **Total Volume (mL):** This is the total amount of fluid or medication you need to infuse, measured in milliliters.
* **Total Time (minutes):** This is the total duration over which the infusion should be administered, measured in minutes.
The calculator will then output the required **Infusion Rate (mL/hr)**.
