What to do if . . .

[beezwax]

beezwax, PADI doesn't have a procedure for an omitted deco stop.

You are right, since PADI is obviously No-D diving. But they do have procedures for "emergency" deco stops, i.e. what to do when you accidentally overstay your No-D limits. These procedures are what I outlined in my previous post, and are printed on all the PADI recreational tables. If you read the original post, you will see that this is what the question was about, NOT omitting a required stop when you are deco diving. (although that is what this thread discussion has turned into)

The problem is that folks that have it together enough to have actually thought it out, come up with a plan, and practiced are not the folks who’d have such a problems in the first place. But I find it had to believe that anyone in their right mind would trust the marketers of the agencies before they'd undertake the protocols that the Navy uses to look after their own.

Thalassamania, I talked to my TDI instructor today and his advice would be to follow the Navy protocol, despite the 2 methods given in the book. As I respect him greatly, it has settled the question for me.

beezwax, the OP's question was how to do an omitted deco stop after surfacing, not how to do a deco stop when you don't have a computer or tables with you. His premise was going OOG before completing a stop, surfacing and fetching another tank, then descending again to complete his deco.

Getting in the water would be just like getting in the chamber. The chamber just increases pressure for you to do deco above water, so going down again would theorectically to the same thing. My instructor said that if it happens, the best thing to do is breath pure o2 until you get to a chamber and have them treat you because thhey know what they are doing.

Red, I really can't understand why you think my posts are off. The OP says he was reading his PADI OW manual in their section about deco stop depths/times if you exceed the no-deco limits. He notes that PADI tells their recreational no-deco divers who've screwed up to hang at fifteen feet for fifteen minutes. It is within this context that he asks his hypothetical question, well what should I do if I run out of gas before I finish the fifteen minutes? Since he is reading PADI, it is only logical to point out how PADI would answer his question. They very clearly say to do this "emergency deco" for 15+ minutes air supply permitting. If you run out before, you're done. That's PADI's answer (the thread turned into a TECH discussion, but it's y'all that are off the OP, not me). I think you will agree that accidentally exceeding your time limits on a No-D dive is not the same as missing a required deco stop on a planned deco dive. If you are over the No-D limits by a few minutes, chances are you could still do a no-stop ascent and be fine. But if you blow by a necessary deco on a deco dive, your tissues are going to be much more saturated and you are going to be at a MUCH higer risk for DCS, and thus you would have much more reason to grab more gas and go back down. The PADI "15 for 15" that the OP refers to is obviously not a deco depth/time for a specifically planned deco profile. It's an "Oh Sh-t!" safety blanket for a messed up recreational dive. 15 minutes is an arbitrary amount-- that's why PADI says to do at least 15. i.e. if you've got more gas, stay longer, it will give you that much more safety margin, but if you run out early, go up and don't stress it because it was a cover-all to begin with. I know I'm explaining this in the minutest detail, but only because you've failed to understand my previous two posts. Please go back and read the OP and you'll see that I'm right.

Finally, the clean clear flash of truth comes through.

I guess the next question is would DAN cover you if you exceed your training by attempting something outside the scope of your training just because you were told to do so by someone on the Internet?

Yes if you follow the directions of the U.S. Navy Diving Manual no one would fault you for that, even if you did learn about the existence of that document and procedure (and maybe even that organization) on the internet.

If all you have is a PADI OW certification, and you directly violate what PADI says to do in this situation, are you negating your insurance coverage for this incident if you do end up with a problem?

The card in your wallet does not change the laws of physics or the way in which your physiology works. Get off the kool-aid (see, there're several flavors of kool-aid available), the U.S. Navy knows more about how to handle these problems than any other organization on earth and just because you only learned about it recently on the internet does not negate that fact.

PADI OW doesn't cover what he wants to do which is surface and descend again with another tank. Thalissimania was the first to answer his question. I questioned his answer then answered my question and now it is all quite moot.

Yeah, I thought Thal answered it long ago ad I'm surprised you are all still here...

We're bored, Dennis.
