This is a blend that has oxygen content less than 18%. As you'll recall, when breathing standard air, the percentage of oxygen in the mix is 21% and nitrogen is 78%, with various other gases making up the remaining 1%. Diving enriched air nitrox is when the oxygen percentage is greater than 21%, and therefore nitrogen is less than 78%. With ...Web

The major gases that comprise today's atmosphere are in Table 4.1.1 4.1. 1. The mixing ratio of a gas X is defined as the fraction of total moles that are the moles of gas X. For instance, 78 moles of every 100 total moles of air is nitrogen, so nitrogen's mixing ratio is 0.78. Note that in atmospheric composition, the mixing ratio is the moles ...Web

A pure oxygen environment eliminates the need to carry nitrogen tanks, eliminates the need to carefully monitor the oxygen/nitrogen mix, and eliminates the possibility of the bends (decompression sickness).
