Do you know what is "high oxygen diving"?
What is Enriched Air?
"Hydro-Oxygen" diving, "Oxygen-enriched" diving, etc. Different names are translated from the term "ENRICHED AIR", which refers to oxygen and nitrogen that are higher than the oxygen content in the air (>21%). The composition of the gas mixture, we use "NITROX" or "nitrogen-oxygen mixture" called. Usually 22% - 40% oxygen is used and nitrogen is mixed for recreational diving.
The use of the NITROX dive has its advantages and limitations, but the most important thing is the safety of the dive (the development of the NITROX is also used for dive safety).
After a good theoretical education and training, with the correct equipment inspection mark, you can have a safer diving environment. The development of NITROX has been decades of history, mainly in commercial and military applications. During this period, there were four large-scale promotions that wanted to enter the field of recreational diving. Due to the lack of basic theoretical conditions for diving population, the cost of NITROX was slightly lower. High, poor penetration, and other factors all contributed to the failure. At present, the world's leisure diving system is still based on compressed air diving.
