Enter the volume (mL) and the time (hrs) into the Infusion Rate Calculator. The calculator will evaluate the Infusion Rate. 

Infusion Rate Formula

The following two example problems outline the steps and information needed to calculate the Infusion Rate.

INFR = V / T
  • Where INFR is the Infusion Rate (mL/hr)
  • V is the volume (mL) 
  • T is the time (hrs) 

To calculate the infusion rate, divide the volume by the time.

How to Calculate Infusion Rate?

The following example problems outline how to calculate Infusion Rate.

Example Problem #1:

  1. First, determine the volume (mL).
    • The volume (mL) is given as: 400.
  2. Next, determine the time (hrs).
    • The time (hrs) is provided as: 8.
  3. Finally, calculate the Infusion Rate using the equation above: 

INFR = V / T

The values provided above are inserted into the equation below and computed.

INFR = 400 / 8 = 50 (mL/hr)

Example Problem #2: 

For this problem, the variables required are provided below:

volume (mL) = 100

time (hrs) = 5

Test your knowledge using the equation and check your answer with the calculator..

INFR = V / T = ?
