Enter the tidal volume and the respiration rate into the Oxygen Flow Rate Calculator. The calculator will evaluate the Oxygen Flow Rate. 

Oxygen Flow Rate Formula

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

OFR = TV * RR

  • Where OFR is the Oxygen Flow Rate
  • TV is the tidal volume 
  • RR is the respiration rate 

How to Calculate Oxygen Flow Rate?

The following example problems outline how to calculate Oxygen Flow Rate.

Example Problem #1:

  1. First, determine the tidal volume. 
    • The tidal volume is given as: 10.
  2. Next, determine the respiration rate. 
    • The respiration rate is provided as: 50.
  3. Finally, calculate the Oxygen Flow Rate using the equation above: 

OFR = TV * RR

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

OFR = 10 * 50 = 500


Example Problem #2: 

For this problem, the variables required are provided below:

tidal volume = 5

respiration rate = 60

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

OFR = TV * RR = ?
