IANTD – International Advanced Nitrox and Technical Diving

Logo for IANTD International Association of Nitrox and Technical Divers_Logo

Up to a certain time, mixed gas diving and decompression gases were used almost exclusively for military or commercial purposes. Because it was quite simple and safe, mixed gases became more popular among some group of divers. In 1985 IANTD or International Advanced Nitrox and Technical Diving was founded to fill the gap and bring these techniques to the public.

EAN – Enriched Air Nitrox

EAN or Enriched Air Nitrox is a mixture of gases for which content is the same as air but at different ratios. It has higher concentration of oxygen than the 20.8% found in regular air. EAN is used to reduce nitrogen exposition and saturation into the body. It gives longer bottom times at given depths than regular air.

Nitrox

Nitrox is another name for enriched air which is a gas mix different than normal air. Other possible names are EAN or EANx where x is the percentage of oxygen eg: EAN32. It is named this way because just like most of the air we breath it is a mixture of nitrogen and oxygen. Nitrox has a different ratio of the two gases with higher oxygen percentage than regular air.
