Enter the partial pressure of oxygen (bar) and the fraction of oxygen into the Calculator. The calculator will evaluate the Max Depth.

## Max Depth Formula

MD = PPO2 / FO2

Variables:

- MD is the Max Depth ((bar))
- PPO2 is the partial pressure of oxygen (bar)
- FO2 is the fraction of oxygen

To calculate Max Depth, divide the partial pressure of oxygen by the fraction of oxygen.

## How to Calculate Max Depth?

The following steps outline how to calculate the Max Depth.

- First, determine the partial pressure of oxygen (bar).
- Next, determine the fraction of oxygen.
- Next, gather the formula from above = MD = PPO2 / FO2.
- Finally, calculate the Max Depth.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

partial pressure of oxygen (bar) = 30

fraction of oxygen = 3.5
