absorbed inert gas

wedivebc

Sorry for the X post but after 24hrs on scubaboard with no reply I figured I was barking up the wrong tree. The real experts dwell here
There was an interesting point brought up by padiscubapro on this thread http://www.scubaboard.com/showthread.php?t=94218 about how if you change to air diluent from trimix then do you deco assuming air you have neglected that you are still offgassing helium into a closed system and it will affect deco.
OK so how much inert gas is actually in our tissue? I expect there are huge variables in the equation but a ballpark figure will do just fine. Is there a way to predict offgassing of the inerts into a loop and could closed circuit computers be programmed to account for it?

Have a look at this post in the "Clean Deco" thread.
Very intresting thread, actually, you'll like it.

No reason a computer couldn't account for it. It would simply involve having the inspired gases change by a small amount on every iteration, very simple if you know how much it changes by.

But why would you want to?

I suppose it depends on whether you think helium is good or bad for deco.

Not as simple as you think.. since a you need to know the looop volume.. its different for every Rebreather and person and second.. The loop volume is not consistent on many rebreathers like inspiration, meg, prism ect within a dive..
