If you follow all the rules, if you train properly, if you keep your equipment properly maintained and (most importantly) if you keep your ego/attitude in check at all times (i.e. don't do dives beyond your training/experience), you should be able to go home at EOD. It's that last part where which most "dead divers" have issues. I can cave dive as deep as 130ft and Open Water dive as deep as 150 ft, but no deeper for either unless/until I complete my mixed gas training. This is where you learn to dive with gas mixes that are less than 21% O2 (i.e. the % or "fraction of O2" (FO2) in the mix). And. mostly, you substitute that with Helium. So, the basic "Tri-mix" course trains you on 18% FO2, 35% Helium and the rest, compressed air. And that should get you down to about 218ft. There is also an "Advanced Tri-mix" course, where you use 10% FO2, 70% Helium and the rest as air. And that can get you closer to 300ft in depth, but only for a short time (like 9 min.). But you must also carry all the other mixes with you and change to/from a given mix as you descend and re-ascend. That 10-70 mix should be your main bottom mix. So, you have all these spare bottles with you. And, at certain depths, you switch to the next bottle and leave the one you were using at that depth for when you return to it on your "deco" schedule. But it all has to do with how your tissues absorb O2 and at what "partial pressure." Too much O2 at deeper depths can actually kill you as PP02 can be much greater than your tissues can absorb. You die from Oxygen Toxicity. Remember, as you dive deeper, the overall pressure on your body increases, thus increasing the PPO2 to your tissues. That's why 10% FO2 works at very deep depths but also why you should never breathe it unless you are at those depths. On the surface, you could get away with only 18% FO2 if you had to. Thankfully, it's more like 21% in regular air.


Trivia quiz: How deep can you go down on breathing pure 100% O2?

I can assure you that there was still one in Australia about 20 years ago, just off the coast road between Cairns and Cooktown. I see no reason it wouldn't still be there. Only bar for miles, I was cautioned to not take my girl there except during the day and be very careful if I went there on Friday or Saturday night as locals got a little lively. We stopped by there but had to make a river crossing before high tide so didn't go inside. I had pictures but don't know where they are now. I wish I could remember the name of it, was in the middle of nowhere.
Maybe some of the Aussies hereabouts may chime in...
