AND the discussions surrounding them.....
1) Often, on my last stop, I have held an ascent line in rough seas and rocked up and down by just a few feet, and not thought much about it. Now, I realize it cannot be optimal for my offgassing physics. I learned what a Jon line is and plan to put a bolt snap on my buddy leash and stash behind my backplate. JB can whip it out if we need it on stops in rough seas.
2) If I ever improvise when putting gear together, I should be careful to think through ALL possible implications.
3) 100% Oxygen can effect outcome profoundly and reduce irreversable brain injury.
4) Long flights set your body up for dehydration and Deep Vein Thrombosis---we know this already, but don't often DO anything differently to compensate. Some of us take aspirin before long flights. Some physicians do too, even when they do not advise others to do so, since there is no real science yet to support it. The consensus seems to be that it won't hurt. On flights, push fluids...drink a lot of water and walk around every couple of hours, it might be more important than we ever thought.
5) Cardiovascular Events are a very common cause of death. (Even our "shark attack" off Maui turned out to be yet another garden variety heart attack...
Aerobic exercise and healthy diet might be one of the best ways to dive safely..
6) Massive PE often presents suddenly and often is not recusitatable. Often rescuers will not find a pulse. (Pulse checks no longer taught for laymen)
7) Dive partners often suffer from "survivor's guilt" and need to be supported and encouraged not to second-guess their own actions.
8) The dive community experiences the loss and sometimes the grief is misdirected and presents as anger against others that may be unjustified or better channeled another way.
9) recompression of venous gas bubbles can reappear on the arterial side of the circulation on bounce profile. All people have a physiologic shunt, blood that is not filtered by the pulmonary vasculature.
10) I was reminded that a diver who has been bent once, is at higher risk to be bent again.
11) Powerful ocean conditions can complicate and prevent timely ocean rescues or even cause death. Extreme conditions require boat captains with local knowledge of surf, wind and currents.
Anybody else have any little epiphanies or concepts that were amplified lately?
