i was wondering if anyone knows of any studies done on nitrogen in the blood stream and if so has there been any proof that is harmful over a long period of time. is it safer to use nitrox?

Some intresting reading and research can be found here.

There isn't any long-term buildup of nitrogen in the body. Once you return to the surface, you re-equilibrate with surface nitrogen tensions.

There can be long-term consequences of poor decompression strategies, however, including dysbaric osteonecrosis (bone death probably due to nitrogen bubbles).

Nitrox is only safer if a) you stay within the MOD of the gas, and b) you dive air tables. If you dive Nitrox tables (therefore maximizing your bottom time, which is what most Nitrox divers are trying to do) you will absorb essentially the same amount of nitrogen you would if you were diving air. It will just take you longer to do it.

Nice reply. I'm in agreement with LCF that Nitrox is only "safer" if you dive air tables.

Shawnwill36:

Please remember that nitrogen isn't the problem After all, you're living in a nitrogen atmosphere (79%).

The problem is going from too much nitrogen to the normal amount too fast.

thanks everyone for the info, i understand a lil more now

That was far more informative than class, my instructor basically just said that breathing Nitrox is healthier and the body prefers it more but didn't really elaborate much on the caveats. Thanks.

If that was the case, there would be no old divers... when in fact there are lots. :)
