The Partial Pressure Calculator – ppO2 calculator considers the percentage of oxygen in a diver’s breathing gas and calculates the partial pressure of oxygen (ppO2) of the gas mix. The ppO2 calculator is an essential tool for divers who want to ensure their safety while exploring the underwater world.
Partial pressure ppO2 Calculator
Formula
The calculator uses the following formula
Depth = Depth in meters
fO2 = Fraction of Oxygen in the Gas (0.21 for Air, 0.32 for Nitrox32)
ppO2 = Partial pressure of Oxygen
We assume that we are at sea level and an atmospheric pressure of 1bar
For Salt Water
ppO2 = ((Depth/10m)+1)*f02
For Fresh Water
ppO2 = ((Depth/10,2m)+1)*f02
Explanation
Air has a weight of approximately 1.29 grams per liter. One atmosphere is the pressure exerted by the weight of the Earth’s atmosphere.
As scuba divers, we generally consent that at the surface we have already 1bar of pressure on our shoulders.
Water has also his weight (1.0Kg for Fresh Water and around 1.02Kg for Salt Water) and the pressure on the divers increase.
In Salt water, for every 10m Depth we go, we add 1bar
| Depth | Ambient Pressure in salt water | ppO2 on Air | ppO2 on EAN32 |
|---|---|---|---|
| 0 | 1 | 0.21 | 0.32 |
| 10 | 2 | 0.42 | 0.64 |
| 20 | 3 | 0.63 | 0.96 |
| 30 | 4 | 0.84 | 1.28 |
| 40 | 5 | 1.05 | 1.60 |
| 50 | 6 | 1.26 | 1.92 |
| 60 | 7 | 1.47 | 2.20 |
- we calculate the Ambient Pressure a ((Depth/10m)+1) for salt water.
- to get ppO2 we multiply the Ambient Pressure with the fraction of Oxygen (fO2)
