equivalent air dive table
A calculator for the equivalent air depth and the oxygen clock.
Enter the dive depth, the oxygen percent, and how long you stay on the bottom. Then see what depth an air table reads it as, and how much of the oxygen clock is used.
Apabila kamu berada di 30.0 m dengan oksigen 32% selama 30 menit, maka tabel udara membaca selam ini seperti 24.4 m, karena nitrogennya lebih sedikit dari udara. Tekanan oksigen di sana 1.28 bar. Jam oksigen untuk satu selam terpakai 17%, dan untuk sehari 14%. Kesimpulannya, oksigen masih di dalam batas, jadi masih aman.
What the words mean
- EAD
- EAD stands for equivalent air depth. Nitrox has less nitrogen than air, so the dive is counted as a shallower air dive.
- Air row
- The depth you would use on an air table. From that row and your mix, you can see how deep you may actually go.
- Oxygen
- The percent of oxygen in the cylinder. Air is 21. EAN32 means 32.
- PPO2
- PPO2 stands for partial pressure of oxygen. It rises as you go deeper and as the mix gets richer. This table marks above 1.40 in yellow and above 1.50 in red.
- MOD 1.40
- MOD stands for maximum operating depth. That is the deepest you go before PPO2 passes 1.40.
- Nitrogen
- The rest of the gas that is not oxygen. Less nitrogen means the air table reads the dive as shallower.
- Bottom time
- How long you stay at that depth, in minutes. This is what goes into the oxygen clock.
- CNS
- CNS is the oxygen clock for the nervous system. One dive and one day each have a limit. The percent is how much of that limit is already used.
- Minute limits
- How many minutes are allowed at that PPO2, for one dive and for 24 hours. The PPO2 is rounded up to the next row.
A planning aid, not a substitute for training or a dive computer.
