Dumb safety stop question!

[grouchyturtle]

1- I know the air in a single wouldn't last.
2- Even if it would, I doubt I'd ever stay down that long anyway
3- It would have been nice of my dumbass buddy to let me know that he already posted this question!

And as he said it's more of a hypathetical question, not like I'm ever planning that dive.

grunzster once bubbled...

Nothing wrong with that type of dive. I done a few and they can be alot of fun.

One thing that comes into play here is the minimum bends depth. I believe current thinking puts it around 18ft(?).

The theory goes that above this depth it is extremely unlikely that a diver can be bent. Ascents to altitude afterwards pose a problem of course.

There's a hotel in Florida that allows you to spend the night (at 15' I believe), afterwards you do a direct ascent. They ask that you not fly or drive over mountains afterwards.

It's called the "Jules Undersea Lodge." I have a link to it from my site.

Pretty cool.

I recall reading somewhere that the inventor of the wheel or of some computer model started at this point that I paraphrase....[Even lying in a bathtub breathing compressed air, there will be some point whereby arising out of the tub will cause DCS[.....I will look and try to recall where that is from.

Anyone else heard or read about this quote that I paraphrased? I cannot remember the author. Maybe the guy that did the PADI wheel??

D***it, I edited that for better punctuation and less redundancy!!

Sorry everyone, seems that I sent the wrong post to the thread!!

I believe the theory goes along the lines of ...

If you do a full saturation dive to a given depth spending more time at that depth is not meaningful - your tissues are already completely saturated for that depth.

If you ascend from a full saturation dive a given number (fraction) of atmospheres, the largest bubble that will be created is still too small to cause a statistical likelyhood of DCS.

I believe 17' or 18' is the current minimum bends depth.

Getting bent coming out of a bathtub would violate this theorized and tested concept. With all due respect, I think this (bathtub bends) may be an urban legend.

Several pc deco packages use this concept to plan dives. In at least one you as a user can set the minimum bends depth as an input parameter.
