Nitrox. Specialisation Nitrox Diver course is the most popular dive-dive to the mix increases the oxygen-rich no-decompression limits.
This means more time underwater adventure, especially for repetitive dives. At week diving expedition on the ship, three dives daily and 1 night before flight plane.
Reducing the amount of nitrogen in the mixture to improve its properties for dives up to 40 meters. As a respiratory agent is safer than air, but you have to stick to the rules. It is important to dive depth and duration of exposure.
In the case of nitrox containing up to 40% can be used oxygen cylinder and regulator used to dive in the air. Increasing depth below 40 m is not possible due to the toxic effects of oxygen at elevated partial pressures above 1.6 atmospheres. The most common is nitrox with 32% and 36% oxygen. You can dive with nitrox air decompression tables, it increases the margin of safety.
The advantages of nitrox:
- Increase the time for decompression dive time in the air,
- Shortness of decompression - decompression dive once, the time spent on decompression is much shorter compared to the air- Increased margin of safety - at similar times as the air diving, we further hold the decompression curve zero
36 nitrox diving can be present at a depth of 22 meters in 70 minutes, for nitrox 32 - 60 minutes, with 37 minutes air-. You can watch a lot more and shoot.
In divers over 40 years of age is recommended nitrox mixture.
