FatCat once bubbled...
Right, this is what I call a dangerous post. The kind of commercial diving referred to here is called "bursting bladder diving" when literally translated from spanish. It's commonly used by coral hunters in the Med.
What are you talking about?
Funny, I just watched US Navy divvers doing this working on the Hunley. That was not years ago, oceans away and I didn't see any of them bust a bladder.
Before you all go off hollering at me, NO!, I'm not a coral hunter. I know some licenced ones though.
But what are you?
If ever you want to see what deep air diving does to people, go talk to these guys. Permanently glassy eyes, shaking, speech impediments,...
I didn't say anything about deep air.
This is completely irrelevent
In water recompression isn't even advisable in real emergencies. Far, far better just to administer oxygen and call for help and a medivac.
Now this is also irrelevent but actually IWR is a very useful option especially if a chamber is weeks away.
Besides, this makes my point. STAY ON THE SURFACE.
Why was he dumping air?
To try to get back down to make a slow ascent. TOO LATE.
If he had missed deco (he didn't, NDL dive) then it is a good idea in many cases to bgo back down and do the deco time.
Please, do us all a favour: read up on the theory, take a couple of courses (the DAN courses would be advisable) and forget about comparing commercial and military diving to rec diving. Us regular divers simply don't have the same physical condition as those guys.
Just exactly what theory should I read up on?
What courses?
Just exactly what would be YOUR suggestion as to how the diver in question should have acted?
And please, never, ever forget that tables and computers are theoretical models. Most of them have no connection whatsoever to reality.
Pardon me?
The US Navy tables were tested and validated by thousands of hours and thousands of dives. They have a solid basis in practice.
Heck, we don't even know for sure what the mechanism behind DCI really is. If you don't believe me, check the european issue of Diver's Alert Magazine (3rd quarter 2003).
