Is there any advantages of using AIR for Deco?

[Jean eve]

Now most of the divers are using gas mixtures(Nitrox) for decompression.How about AIR?Is there any advantages or it is useless??What I know is,the time using AIR to decompress is longer;not so effective as using higher O2.
Any disadvantages besides this?

Why??
Anyway it still help our tissue to offgasing isn't it?
Using higher O2 to deco is better than air ,but is it so useless?
Thanks

None.

It can still be used to inflate the tires to bring you to the divesite (but even there are gases are better)

With the longer times and the greater potential for tissue damage, planning to decompress on air is hard to justify.

If the defecation has contacted the impellor, decompressing on air beats the heck out of getting bent. It should not be plan "A" or plan "B".

So you mean doing the whole dive on air? maybe if your doing a stop at 220ft but even then I dont think too manyu folks use air

Probably beats the heck out of breathing water too! (but I know what you mean!)

That is plan "Z".

Oh give me a break....... divers have been decompressing on air since the year dot and quite successfully too. It is only over the last few years that nitrox has become readily available in some places and been de mystified that it is now seen as an advantage because of the shorter stop times etc.

advantages of using air for deco:

1 you can get it anywhere
2 it is cheaper than nitrox or O2
3 no Oxygen toxicity problems
4 no need for gas analysis
5 less tanks
6 no gas switching errors (primary cause of death in tec divers)
7 simpler decompression planning
