Local takes a hit

[nereas]

Thanks.

Yea, I could try to start drinking as soon as I come out of the water next time. That way the symptoms would be ofset some.

Dehydration would be my guess as well.

Can you tell us the depths and bottom times of your dives?

Tweren't the sort of drinking alluded to.....

But on a serious note: what is most troubling about this sort of "hit" is the total absence of other DCS indications, and the fact that profiles were generally "safe". Almost like some other mechanism is involved here that is still a mystery. Reading some of the medical literature indicates no one knows what is going on.

"Generally safe" is always a function of working up to individual limits, I believe.

I don't think you can look on a table and get the right answer every time.

For technical diving, to work your way down to new depths and/or longer times, you always need to work towards this gradually. In this manner, you "customize" your own limits, as it were. And every new dive season is sort of like starting over again. It seems to me that NDL diving should be somewhat the same.

Dehydration is often a variable factor. So is adequate sleep. So is surface interval needed. So is alcohol consumption after a dive, or even coffee consumption.

And then there is age. It could be that simply with advancing age, something changed, and that may have been related to the unexpected hit.

nereas, if you take a look at rockjock's profile page you would see that most of your last post sounds pretty uninformed. As long as your at it, take a look at ScubaandDreams profile and you would see that rockjock's buddy on this standard dive trip is one of his current technical instructors, and a more than competent mentor.

We do not have dive seasons here and a 36 year old rock climing doubles wearing military man is most likely not having issues with aging. The majority of the regulars in the Hawaii Ohana have done that pair of dives more than once, and the fact that his Suunto was OK with both dives points to them being on the conservative side.

As I am the reason you are now part of this thread, I feel obligated to inform you that you are not scoring any warm fuzzies with the tone of these two posts. :no

Wow, long demurrer. Let me touch base on your various items.

I am a lot more interested in unexplained hits for personal edification reasons than I am interested in scoring warm and fuzzies with locals half way across the globe, with all due respect.

And I did not scour all the profiles of all the players in this drama either. I don't have that kind of time on my hands.

Nor did I presume any of them to be tech divers or instructors. So thanks for that update.

It would have been relevant to see the profiles. If they were tech profiles, which we are not told, then the hit is less surprising to me, simply because of the enhanced complexity of such a dive. Is that what you are saying then??

I was thinking in terms of NDL profiles. And every NDL hit that I know of resulted either from (1) pushing NDL limits, or (2) flying too soon after diving, or (3) alcohol, or (4) trying to do your dive planning in your head, or (5) diving with air as though it were nitrox. Those may all be completely irrelevant in this instance. But remember, I have not seen the profiles, so how could I know that? Fair enough?

Here are some more details I can share to stave off inter-member spats.

Myself (for those who don't know);

36, 5'9", 175lbs, Active duty military.
Run, walk, hike, dive (lots)

experience
2 years diving
over 200 dives
dives from charter boat, shore, kayak and the "Rubber Ducky"
approx 40 technical dives to include
Deepest dive to date 181fsw
Longest dive to date 2hour 31min
Dive rec and tech
-wreck penetration
-wreck exploration
-surveys
-pure fun
Certs up to
PADI MD
NAUI Tech, Advanced nitrox, Deco procedures, Helitrox, Technical Wreck Penetration andTrimix I (1 dive left)

The dives in question (25% in my tanks, but diving as 21%)
Gear - doubles, with my normal full tech esemble
Purpose of dives- one buddy adjusting trim for a different set of doubles and general skill practice (s-drills, v-drills, etc) for the 3 of us all done within rec limits.
Dive #1 - Sea Tiger
101fsw max 90fsw avg - 20 min bottom time with nice slow ascent
2 minutes up to 50fsw, 3 min up to 20fsw and then 3min SS
1hour 33 min surface interval (relaxed sitting on boat and shore and drinking water)
Dive #2 - Kewalo pipe
61fsw max - 46fsw avg - 39 min bottom time with nice slow ascent
1 minute up to 30fsw, 1 min up to 20fsw and 3 min SS

--Edited to add --
My ears clear on auto and I had no problems clearing and no ear pain during or after the dive. No ear pain during ordeal either.
-----

Seas were about 2-4 foot that day so little effort on surface and minimal surge/current on the dives.

I always drink water and had a good breakfast that morning.

Hope this clears some up.

By the way--Thanks again to all the support from everybody. I am trying to keep you up as I get more information (MRI scheduled this week and Audiology next week). If they find anything I will pass it on. I haven't been on much in the last few days becasuse I am just trying to catch back up at work as Monday was my first day after the incident.

Many thanks, Rockjock3 !

All well and good, but do take into account that this is the "Hawaii O'Hana" subsection, and when the OP posted here, it was under the assumption that anyone reading/commenting on the post was a regular on here and knew his history/stats. If he had posted on a general section or the DAN section, I can see the problem of not giving enough details.

Also, yet again, we are the Hawaii O'Hana, we like warm and fuzzies from across the globe if you post here!:sappy:
