Thank-you. I really appreciated that article. Now
I'm curious about this statement:
When a cave diver breathes too heavily at
extreme depths[...]carbon dioxide can build
up in the lungs, resulting in a blackout.
I once got a terrible headache on a 69foot/41min
dive in Monterey. I was told that it was probably
from CO2 build up because I was trying very hard
to not use too much air(I'm a novice and was
diving with a very experienced diver that used to
be an office mate -- I didn't want to penalize him
for buddying with me). Obvious CO2 can build up
if you don't breath enough. But can CO2 build up
from breathing too *heavily*? Is that be a re-
breather thing, like it can't scrub faster than
you can make it?
That's incredible. In addition to the obvious human interest of the story, I had no idea people could even dive that deep with no pressure suit or submersible.
I think that it is a perfect example of how task loading can quickly, real quickly, become overwhelming. So sad. That is some extreeme stuff.
Exactly my thought it makes you realize that something as simple as moving your light can be a huge change in extreme circumstances. It is a very sad story, and it makes me appreciate the dive community even more for how they watch out for eachother. Dave Shaw's story is nothing short of heroic.
