Nitrox Oxygen toxicity

sydney30

For example, the maximum operating depth of nitrox with 36% oxygen, a popular recreational diving mix, is generally around 29 metres/95 feet. The exact value of the maximum allowed ppO2 and maximum operating depth varies depending on factors such as the training agency, the type of dive, the breathing equipment and the level of surface support, with professional divers sometimes being allowed to breath higher ppO2s than those recommended to recreational divers.

To dive safely with nit [...]

Richness of Nitrox mix

sydney30

The two most common recreational diving nitrox mixes are 32% and 36%, which have maximum operating depths of about 34 metres / 110 feet and 29 metres / 95 feet respectively when limited to a maximum partial pressure of oxygen of 1.4 bar. EAN32 is common because it is the mixture with the maximum concentration of oxygen that allows the diver to go to the full depth of recreational diving's "No Decompression Limit" for air.

The second reason is that richer mixes extend the [...]

Nitrox Naming

sydney30

In its early days of introduction to non-proffessional divers, nitrox has occasionally also been known by detractors by less complementary terms, such as "gas devil" or "gas voodoo".

Although "nitrox" usually refers to a mixture of nitrogen and oxygen with more than 21% oxygen, it can refer to mixtures that are leaner in oxygen than air. "Enriched Air Nitrox", "Enriched Air" or "EAN" are used to emphasise richer than ai [...]

Nitrox Purpose

sydney30

It is generally untrue that breathing nitrox can reduce the effects of nitrogen narcosis, as oxygen seems to have equally narcotic properties under pressure; thus one should not expect a reduction in narcotic effects due only to the use of nitrox. For a reduction in narcotic effects Trimix gases which also contain helium are generally used.

There is anecdotal evidence that the use of nitrox reduces post-dive fatigue, particularly in older and or obese divers; however the only [...]

What is Nitrox ?

sydney30

Nitrox refers to any gas mixture composed (trace gases excluded) of nitrogen and oxygen, this includes normal air which is approximately 78% nitrogen and 21% oxygen, with around 1% other gases. The most common use of nitrox mixtures containing higher than normal levels of oxygen is in SCUBA diving where the reduced percentage of nitrogen is advantageous in reducing nitrogen take up in the body's tissues and so expend the possible dive time and/or reducing the risk of decompression deseases ( [...]
