My Adventure with type2 Decompression Illness

The gas choice wasn't causal here. Plain and simple. And being an ******* about that in the long run dissuades others from posting their accidents.

Look to the greater good. We need to encourage, not discourage, posts like this one.

Sorry I am not all warm and fuzzy. I will not speak of your end again.

Thanks for all the replies. I will be doing some things different in the future. new deco software. leaner (O2) bottom mix. ect.
To Nick(caver95) If your motivation is because you don't want to see anyone die why do you assume and insult me? I can't believe you would say I broke 1 of the 5 rules of cave diving. You don't know me or my level of training. Or that you would insinuate a 170' END would cause me, or was the cause of Craig and Johns accident in Eagles Nest. Or you would compare a 150" END to not turning a dive at 1/3's.
When I started cave diving there were no dive computers, no commercially available reels, primary lights, or trimix. We dove all the deep stuff on air. Wakulla, Sally Ward, Little Dismal, Diepolder 2 and 3, Little Salt springs, Salt springs, Garden World, the Jewel, Lake Tarpon sink, Eagles Nest, the end of the line in the Lockwood tunnel at Eagles Nest. Caribbean wall dives to 275'. I've done them all ON AIR! I do not dive like that any more but I wouldn't even consider mix unless I'm diving below 200'. So sweating a 170' END is laughable to me. You should read what Sheck says about deep air diving(thats if you respect him).
I'm sure this will convince a lot of people that I'm an irresponsible diver. I don't care. You may think this kind of kind of diving isn't right. Thats O.K. for you but don't tell me how to dive. My D.C.S. had nothing to do with END or O2 %. Peace, Gary Lemme
or

Have you ever taken tests to show that you're as alert/responsive/quick/sharp at 170ft as you are at 100ft? My experience is that divers think they're much better at depth than they really are... and really... Sheck... about depth....you know how he died? I respect the hell out of him, but his obsession with depth.... he'd probably still be with us without that.... and he's probably the outlier in any study about the effects of depth on humans.... most likely... YOU'RE NOT SHECK....

AA,
Gary has come on and said that he will adjust his O2 & END on future dives. I did not see his post or I would have worded my post different so you have a point. This is the "Incident & Analysis" thread where we are supposed to discuss and analyze.

Gary,
Thank you for making the adjustment to your deep diving.

I have been around for a while as well and have done the deep air dives a long time ago. What I have seen over the years is a perpetuation of diving deep air and having deep END's because others did it in the past. I have found that lowering my personal END's gives me more clarity on dives and that others who dive with me tend to keep theirs more conservative as well. There have been too many incidents that deep END's are considered a significant contributor. Again thanks Gary, I believe your adjustments will not only make your deep diving more enjoyable and safer but will also influence other divers to follow in the same direction.

Huh? What does my butt have to do with this? I'm confused...

I think he meant curator's butt, ... er END.

I'm late to this thread but it sounds similar to my "hit" a year and a half ago. No deco dive, well within limits and similar symptoms after I got OUT of the water. Table six and then a trip to my ENT. Micro tears in the middle ear. I now take Triptone before every dive and clear early and often. Still get dizzy spells when I move my head in a rapid manner, no trouble in the water. I have been prone to motion sickness all my life. ?????

I am a newb compared to many of you but couldn't the ppN2 be considered "causal"?
If this was indeed a case of DCS, at 4.86ppN2 there is considerably more nitrogen to absorb into your system than if using something like 10/70 with a ppN2 of 1.83.
I understand most are discussing the END component, 170 vs. 43 (on something like 10/70) however the fact that there is a considerable amount of nitrogen for tissue loading does seem to be a contributing factor to this result.
If i'm way off please correct me. Thanks

Cum hoc ergo propter hoc fallacy.
