Well i was on the the boat with scubaeee. Well from what saw, I would say AGE.. Look up pulmonary barotrauma.. It describes the accident as sudden . And man it was sudden,, I believe she had pasted right at the surface. Her dive partner escorted her to the surface and looking in her mask said she fine till the hit the surface,... A little more info is that her dive buddy computer defaulted to 50% eanx after he neglected to change for the second dive and he continued the dive.As i made my 8 minute stopto expel air she joined the line and the was some confusion with the group as the all started check one another computers, they had entered into a deco dive.. ... .. we started 02 immediately and she took shallow breathes but never responded.hope this is not to much detail ..I pray for her family and her .

I'm far from an expert on any aspect here, but Pulmonary and Arterial Gas Embolisms are different, yet can resemble each other in the initial symptoms I think. I think that PGE would be obvious on a autopsy, whereas an AGE would be less so, isn't that right? No medical problems found on the exam, OxTox, NNarcosis ruled out for the hang line depth. Sounds like it's down to DCI or AGE, doesn't it?
One of the predive checks I do with buddies on Nitrox dives is to ask if his/her PDC has the Default turned off. That feature is there for legal reasons, and causes problems. Nonetheless, a dive with a misset PDC really should abort, unless a back up PDC or plan is utilized. That diver is not here to address this, tho.
Speculating further - in hopes of learning from the tragedy, it's stated that
"...they had entered into a deco dive..." and I take it that her PDC was also in Deco? Too many things going wrong on the same dive could possibly lead even an experienced diver to a panicked rapid ascent...?? Gawd have I been there, and I was just short of panic on my Oh-No dive off of NC once; my last maneuver was indeed a questionable one that could have gone badly.
The lessons I think I'll take from this sad loss, in the young divers honor: Address and resolve the problems in the water if possible, but when things continue to go wrong, abort cautiously but early.
My condolences as well to her family and friends on this board and off. We do not use the victims' names here so that these discussion will not show up on Google searches, but we also want to treat these discussion with respect for the sad loss - and I join the others here in that sentiment.
