How deep can u go?

[jbd]

If I recall correctly, a hog was subjected to a depth of 5,000 fsw in a chamber and survived. Not sure what damage might have been done the anatomy of the bones etc etc. If my math is correct I believe that a tank charged to 3,000 psi will not let air out at a depth of 6701.69 fsw. This ignores the effect of the temperature changes involved in taking the tank to that depth.

Me: “Yawn, … um,,, could I have an order of fries to go with that?”

JMHO.

I forget what the min % is to sustain life - for some reason the 12% sticks in my head but I am not sure.

12% might keep you alive if you were asleep, but an active diver needs at least 16% O2... and you'll get exhausted quickly if you exert yourself at that level.

Is there a maximum limit to how deep scuba can take you?

It is either 35,810 or 35,813, depending on which reference you believe.

YEEHOOHAAA!!!!! Good one!
I'll have my burger with two beef PADIs.

What happens at 2065 feet? It's interesting that the current record is exactly one-half of that.

Somewhere past 2000 ft the breathing medium becomes too thick for the human body to be able to breathe it, even if it is mostly hydrogen.

Hyper oxygenated flouro carbons may change this. Basically you end up breathing a liquid and therefore eliminate many of the problems associated with gasses.

Seahound, dont let the troglodites give you a hard time, I reckon the maximum depth of the ocean is the maximum depth of diving, it is just that we dont have the technology yet. The people that are giving you a maximum depth are the people that would have told you fifty years ago that man will never get to the moon or mars.

the 1000' limit has been broken on open scuba, and I believe comercial divers have doubled that. who knows where it will end.

Good question the seahound.

I know, I know, 7 dives and wanting to film a baby at 200 ft. This sounded like an honest question tho. Give the guy some honest info.

For info about (as far as I know) some of the deepest dives done, one may turn to the French operation COMEX: http://www.comex.fr/Pages1/Som.html

They routinely do relatively deep working dives, but what's interresting is their recent 701m exposure (chamber ride) of one of their comercial divers (http://www.comexdiving.com) -- which supposibly is a world record. I think that it was done with a (very very hypoxic) Hydrox as bottom mix. I think that there were two divers going for the ride, but one of them bailed before getting to the equivalent preasure of 701m. Quite impressive feast, to get a diver to that preasure on an experimental mix, and get him back without getting him bent.....

I do not know the world record for "wet" exposures on open or closed circuit.

Be warned, though, that when these guys do these exposured, they do so with exhaustinve surface support (several on-site recompression chambers etc), education of the divers etc.....
