Who's using 100% O2 for deco?

Interesting. I have always thought that I was getting hits in the same places, and figured it was due to scar tissue. But during the last year I heard a doctor from DAN tell me, when I asked him that same question, that the odds really aren't in favor of getting a hit in the same place twice, and that there wasn't a correlation between location of scar tissue and location of the hit. Actually, he says that one of the first screening questions they ask at DAN, when you call in, is where the supposed hit is and had you ever had a hit there before. If you answered it's the same place as before they usually remove you from the suspect hit list.

:huh: Really?!??! Based on that one answer??? I don't get it - seems awfully caviler.

Hrm, interestingly enough a two of my dive buddies have had repetitive symptoms in the same area, and they seem to have nailed it down to specific depth/time limits where it begins to be an issue.

Yea, me too. If I don't do certain stops it's always my around my rotator cups and/or swelling in my upper arms. At first I thought he misunderstood my question but when he mentioned same hit twice as being one of the ruling-out factors I figured he meant it. Anyway, it has made me question a lot about what I thought I knew.

I went back and checked and he's not a doctor with DAN but a medic with DAN in Raleigh/Durham. Sorry for the bad on his title.

Is it possible the medic got it wrong? That the "same hit, same place" was NOT an automatic "not DCS", but a "high suspicion of DCS"?

This I have found true.

yeah that sounds like suspect information about the same hit/same place. God knows i have had my run ins with DAN. While I do not doubt that they work very hard to be on the cutting edge and add a lot to the sport, like all humans sometimes they/individuals come up with some questionable information.

that just does not have the ring of truthiness behind it.

DAN can only comment on the *facts* they're given permission to use. DCS is something most divers wont admit to, so DAN's ability to collect data is limited.

I had repetitive symptoms but different (yet similar) areas. Both elbows...right on one dive, the left another dive a year later.

I believe it had to do with heavy exertion of hauling myself and double 130's out of the water.

I added some extra time on my last stop and all my "issues" went away.

I guess the models didn't account for skinny guys and lots of gear. lol

That's an interesting point. Would any of the rest of you consider yourself skinny?
