Deco with too less air, options from the book

[Rhone Man]

Again, not to keep a circular argument going, but I am just not sure how stupid it is.

I have never heard of nuclear war or alien invasion affecting dive planning. But I most certainly have heard of people running out of gas. Should it happen with proper planning? No. Should any accident (dive, car, surgical or any other) happen if you have proper planning? No. Do accidents somehow happen anyway? Yes. Ergo sum, it is worth thinking about how to deal with it.

If you ask a stupid question you can expect to get a sarcastic and blunt response. And it was a stupid question.

I disagree with your view on this.....who set you up the be the SB judge of the quality of questions?

In diving everything and anything is possible regardless of the expense and time in planning, this is a fact.

In regards to this thread and the OP's question many of us gave honest opinions and tried to reply with constructive thoughts regarding the OP's original thought and statement.

Hopefully someone has gotten a bit of insights from the varied well intended replies, they all don't 100% agree on a solution but least several of us gave an opinion.

Safe and happy diving.

I did answer - like others informed him it was a ridiclous question and a situation that cannot happen if proper planning is used.



Neither. Id make sure enough gas was available to do the stops. Which is the whole point of this.

Or you could not post if you have nothing but sarcasm.

Thought this to be appropriate for some in this thread . . .

And I thought I was the cynical jerk. It is an excellent and very important question. If you are too dull to imagine the multitude of situations where a diver could find himself in deco with too litle gas than why comment on the thread?

I also would choose to forego the shallow stops in an attempt to salvage the fast tissue. My answer is to "rush" (at 60 feet per minute), by using positive bouyancy (not kicking) to the deep stop, hang there a little, re-evaluate gas supply and then resume the safest ascent possible. I would stay at 30 feet until it became hard to breath and then make a very leisurely (1 minute) ascent to the surface. Then all hell would break loose while a screamed for help. Jumping back down with another tank (or some oxygen) is often possible and is likely to result in no injury.


Shooting up to 10 feet and hanging there until your gas runs out would not be best unless gas supply mandated it.

While I have no intention of ever being in this particular situation, I find the discussion on fast/slow tissue to be interesting.

I have never heard of nuclear war or alien invasion affecting dive planning. But I most certainly have heard of people running out of gas. Should it happen with proper planning? No.

Which answers the original question. Plan your dives. THAT is the correct answer to the above. Blindly stumbling through a cluster **** when you've already done 4 or 5 things wrong and STILL stayed down what makes you think they're suddenly going to be capable of getting ANYTHING right?

Should any accident (dive, car, surgical or any other) happen if you have proper planning? No.

Actually yes. There are many factors there outside someones control. Which isnt the case running out of gas diving - that is ENTIRELY within the control of the diver.

Im just as entitled to post as anyone else. And if i believe someone is being pathologically stupid i'll say so.

No its not a fact. Prove it. Lets have a plausible example of how its going to happen. Don't state things as fact unless you can back them up with proper evidence.

So "plan your dives" isn't constructive?

So lets have some proper examples of how you can not have enough gas for deco WITHOUT being moronic and not bothering to plan properly.

I think the OP was asking about decompression THEORY and ended up getting involved in a long discussion about technique so let me ask it another way.

You have a deco obligation and for some reason you have to get out faster than planned (school of sharks taking runs at you, dry suit floods in really cold water)
Do you shorten all stops, do deep stops and shorten shallow stops, blow off shallow stops, and how does each circumstance affect decompression.
