Nitrox and EAN are terms used for oxygen enriched air. By adding additional oxygen to normal breathing air we reduce the amount of nitrogen in the gas mix. As nitrogen is the controlling element for no-decompression limits this provides a number of benefits; we are able to extend our bottom times or add conservatism to our dive planning.
Nitrox has been popular in sport diving for many years and it allows divers to continue to plan air dives but use nitrox to add conservatism to the dives, especially as age and fitness start to diminish during our more mature years. It is now more readily available at most modern dive centres and it is very easy to understand with the correct training. Nitrox courses can be completed in as little as one day.
The objective of the PADI nitrox course is to train divers in the benefits, hazards and proper procedures for using Nitrox mixes from 22 percent to 40 percent oxygen content.
Student Prerequisites:
- Minimum age of 15
- Minimum certification of diver or current enrolment in a diver course
- The Nitrox programme may be taught in conjunction with an Open Water diver certification
- This course includes one session of theory and two dives (one full day of diving).
