recipe is simple. Get off the bottom, get shallow, breathe a heavy O2 mix. The end.

I am pleasantly surprised the instructor suggested doing AN/DP. Way more bang for the buck, and a few times in doubles and it will feel pretty normal.

I'll try to add value by listing what I carry spare on the dive. Cutting tool, 1st and 2nd stage (doubles plus deco bottles), lift device (drysuit or bag), a double ender dog clip. Maybe a mask if I'm feeling quilted by my instructor.

I dive 70/70, but would dive 90/70 or more without concern. Get off the bottom and hang on O2 in the shallows with air breaks. The end.

Sounds like some of it might have been mental, plus dehydration, and lack of electrolytes. These matter for good systematic function.

maybe try keeping the bubble of your wing in the bottom too, that should tilt the fulcrum forward and counteract a head's up position.

I've only ever heard of 80% vs. 100%. 80% mainly advocated for to reduce oxygen stress and if you are in rough seas. I've personally only used, seen, and been taught 100% for my last deco gas. I don't have an issue with 80% other than it's not as good as 100%, especially considering that you can...

I think I need to better understand what you consider to be common, as using my definition I don't believe this to be true. Of the many tech divers I've dived with, I've only known one to suspect he had an incident by borrowing a regulator that was supposed to be clean but was dirty. I haven't...

Have tables, dive with a non-ai computer and a separate depth gauge/timer, and use an spg.

I'm using an Ano 2300CLX now. It's a good light.

Nope, just me implementing something that seems reasonable. @Duke Dive Medicine is Dr. Westman participating too?

The things I've read on consuming antioxidants have been issues with bio availability sufficient to offset increased exposure to (oxidative stress?) oxygen. Any thoughts on that? I actually take ibuprofen before diving to try and help with the inflammatory of response of bubbles flowing through...

Thanks for all the indepth info.

Thanks. How long was the boat ride to the "site?" Also, what was the site? Was there some feature or actual sunken object you guys were on? Cost? Thanks, Mike

That would be really interesting too. Do you know if he has worked with Dr. D'Agostino? He's done work for the DoD to try and influence the onset of O2 toxicity in military divers as well as exogenous ketone usage for special operations forces during missions.

Surely you knew this to be true prior to posting this message and irrespective of the replies to this thread :).

I'm guessing there hasn't been any work on this but I'm curious of thoughts on whether diets that reduce systemic inflammation would be expected to reduce the inflammation experienced post dive and possibly increase one's tolerance of decompression stress before resulting in decompression...

I'm no expert, but I shoot for 1atm/min and probably go slower than that every time. That said, I'm usually within a couple minutes of my tables. We do need to keep in mind that we're diving within an envelope of safety, the boundaries to which are very fuzzy to us or our computers. I would...

Any idea on the dive profile? Please do post after the trip on how it went. That is definitely in range.

Recently moved to northern VA and have been calling around to see who operates over the winter months. Only place I've found so far is Olympus in NC. Anyone know of any other shops in the NC to MD area that operate in the winter? I'm googling ocean city MD now.
