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

To calculate the oxygen flow rate, multiply the tidal volume by 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
