Physics of diving question...

[Hydro]

ahahah gen chem stuff... i'll make some inquiries later, but right now im exhausted on all fronts, so i don't wanna activate that part of my brain... as i recall half lives are fun.

ok this post perked me up a little..

1)i don't think you need to know what exact tissue is fast and slow, i think its the idea that while some tissues can adapt faster you will still have more saturated tissues, and over time you will get a wider gradient of saturation.

just because some tissues will adapt faster, you will still have slower compartments that will require surface intervals to get back down enough to have decent non deco diving time. the opposite would be true for faster tissues being affected more when descending. ( being bored at work i like to read pubmed articles on diving and i recall there was something that talked about the relationship of fast descents and getting narc'd vs slow descents but greater possibility of deco problems later?)

2)i think its more important to know there is a difference in compartments... look at the graph on the link and it will show how the different compartments respond much differently to pressure over time. i think its cool how the fastest HL becomes the most saturated compartment and then becomes the least saturated the fastest... so depending on how saturated you are would have a big effect on your ascent rate... so assuming you make a miscalculation and ascent too fast for your offgassing, you could blow an mvalue for 1 of the 3 possibilities 1) blow an mvalue for just the fast HL compartments 2) just the slow compartments 3)blow the mvalue for all compartments in the worst case.

3) similar response to 1, i think as long as you are aware there is a different compartmental mvalue what part doesnt matter unless you only want to risk a certain compartment of your body? things like ascent rate would be more aimed at your fast compartments in a no deco stop situation... and no fly time would be related to your slowest compartments. surface interval between dives would be aimed at keeping your mid compartments down.

4)i dont think recreational diving gets that technical in dive planning, its not just theory, there are a bunch of studies with saturation data (i don't have a good reply to this.)


(i'm open to disagreement here, since im no expert)
