RE: SAFETY STOP USING 02 or Nitrox.
Hi. I'm doing my Divemaster course and learning all about the wonderful world of gases etc..
Just then a thought struck me.
Hypothetical question - What if a diver had spent too long under the surface - lets say for example he spent 40 minutes at 40M. He was using regular air. (The group is out at sea in a small dive boat - they have an emergency 02 bottle.)
Let's say he got lost or stuck somewhere under the sea. His safety stop would outlast his air supply. Air tanks are dropped down to help him decompress longer.
Would it help prevent DCS if a tank of pure02 or Nitrox was lowered to 5M so that he can decompress faster or at the very least be more beneficial than breathing ordinary air?
I know that breathing pure02 at 2 atmosphere is deadly. But at 5m what would the effect be for 10minutes?
If that is too hazardous - would a Nitrox mix of 30%O2 be more helpful than just normal air?
