Enriched Air Nitrox Diving
Enriched Air Nitrox Diving… (EAN) refers to a nitrogen/oxygen mixture with a percentage of oxygen higher than the 21 percent found in normal air. Nitrox 32% is probably the most common and tanks filled with EAN are usually marked with a Nitrox Green and Yellow tank band with the mix percentage. The higher percentage of O2, and the lower percentage of Nitrogen, allows divers to extend the no-decompression limits, shorten surface intervals or to stay well within the No Decompression Limits (NDL) and get an added safety buffer for decompression sickness in certain diving circumstances.
In conclusion, Enriched Air Nitrox Diving allows divers to spend more time underwater within the NDL by reducing the amount of Nitrogen while increasing the percentage of Oxygen in the breathing gas.
It is important to know about the physiological effects of Oxygen at depth as well as calculating Maximum Operating Depths (MOD) for the specific mix you will use during your dive. Also you can calculate the best mix when you want to go to a specific depth.
