Nitrox Diving Course structure.
With the PADI Nitrox Course scuba divers learn the following
- Techniques for getting more dive time by using enriched air Nitrox with computers
- Enriched air scuba diving equipment considerations
- Enriched air considerations, including managing your oxygen exposure
- Personal Instruction on using “Anlox” gas Analyser
- How to set your dive computer
Nitrox while scuba Diving can benefit all types of diving while in Phuket, but it goes especially well with the shipwrecks that tend to be at some of the deeper dive sites, Nitrox diving at the “Famous King Cruiser Wreck” maximizes your exploration time. As you may remember when you dive on normal air the deeper you dive, the shorter your no stop dive time (NDL), however when using Nitrox the no stop diving time is increased, giving you more time at depth when diving with a dive computer, allowing your 3rd Dive on a 3 dive day trip to be a deep dive at Koh Dok Mai dive Site.
Underwater Photographers usually like to make several dives a day so they can get lots of pictures, by reducing the amount of residual nitrogen you accumulate during the first dives, will allowing your repetitive dives to be longer.
The Nitrox course also counts and is credited towards your Master Scuba Diver rating – the highest non professional rating in the PADI recreational diving Courses
What is Enriched Air Nitrox
Nitrox is a mixture of oxygen and nitrogen that is used as a breathing gas in scuba diving. Currently the air you are breathing now contains only nitrogen and oxygen, any other gasses are only present in trace amounts. The name “enriched air” is the given name that the mixture of oxygen and nitrogen has a higher percentage of oxygen than normal air more than 21% oxygen; air that has been enriched with additional oxygen.
Enriched air nitrox is abbreviated EAN, Nitrox may contain any percentage of oxygen greater than 21%, the most common mixtures are EANx 32 % and EANx 36 %. Special training and certification is required to dive with Enriched air nitrox.
Six reasons for taking the PADI Nitrox Course:
1. LONGER BOTTOM TIMES
Recreational Scuba Divers using nitrox (21 – 40% oxygen) breathe air containing a lower percentage of nitrogen than air. The reduced percentage of nitrogen in the Nitrox tank is a lesser % and allows divers to extend their no-decompression limits in comparison to a diver on normal air, by reducing nitrogen absorption – the less nitrogen there is in a diver’s breathing gas, the slower his nitrogen absorption will be at a given depth.
For example, according to the National Oceanographic and Atmospheric Association that created the no-decompression dive tables, a scuba diver using Nitrox 36 (or NOAA Nitrox II) may stay up to 50 minutes at 90 feet of sea water, while a diver using air may only stay a maximum of 30 minutes at this depth.
2. SHORTER SURFACE INTERVALS
Scuba Divers using Nitrox absorbs less nitrogen for a given depth and dive time than a diver using normal air. This means that the Nitrox diver has less nitrogen to off-gas during a surface interval, which can shorten the required surface intervals between dives. Ok so a diver using Nitrox 32 can do a second 50 minute dive to 60 feet after 41 minutes, while a diver using normal air must wait a minimum of 8 hours to repeat the same dive (using to NOAA’s no decompression dive tables).
3. LONGER REPETITIVE DIVE TIMES
Nitrox blends becomes especially useful for divers who engage in more than one dive per a day. A diver using nitrox will have a longer allowable bottom time on a repetitive dive than a diver using air because the diver using Nitrox has absorbed less nitrogen.
For example, after a dive to 70 feet for 30 minutes, a diver using Nitrox 32% can stay at 70 feet for a maximum of 24 minutes if he immediately re-enters the water. However, a diver preforming the same series of dives on air may only stay at 70 feet for 19 minutes on his second dive (according to NOAA’s no decompression dive tables).
4. REDUCED EXHAUSTION
Many divers claim to feel less exhausted after a dive on nitrox than after a comparable dive on air. By reducing a diver’s nitrogen absorption, Nitrox may also reduce a diver’s post-dive exhaustion.
5. SHORTER DECOMPRESSION
Technical divers use nitrox to reduce decompression requirements. If nitrox is used throughout the dive, the diver may require shorter or fewer decompression stops. If nitrox is used as a decompression gas (the diver only breathes nitrox during the decompression stops), the decompression stops will be shorter.
