Recreational Trimix

On a more serious note, thanks for posting this, Kev. Very interesting, concretely measured information.

Just be aware that those are for lipid solubility. If you want to extrapolate that tissues like bone, blood, muscle, etc., go ahead.

At the end of the day, we're all playing guinea pig anyway.

Sometimes even within a prescribed general deco profile, you have to tailor it to your own individual physiology. The GUE rule-of-thumb of diving 30/30 triox like Eanx32 utilizing MinDeco/ascent rules resulted in the "chokes" for me, after two repetitive dives to ave depth 24m with a 90min SIT a few years ago. I now use Oxygen for deco on the last repetitive dive when using recreational triox (which was recommended to the OP as well instead of deco'ing out on triox backgas).

I'm an experimentalist too and have gone thru lots of trials & errors () --and like to share my real experiences both good & bad with honest & plausible explanations. (NOT unlike in this instance, the ignorant flippant generalizations and bizarre "food-groups-as-metaphor" posts above ).

Kev...how many times have you been bent?

Notice that neon has a low mass transport coefficient, almost 2 times smaller than helium. We should all be diving neox. Or at least quadmix (Ne, He, O₂, N₂). We are all such nickel rockets... I kid, I kid.

On a more serious note, thanks for posting this, Kev. Very interesting, concretely measured information.

Neon is used in some circumstances but if you thought helium was expensive, Neon can increase that by a factor of 10! Plus its a dense gas so causes WOB issues etc.

meh... it's all nickel rocketing... I'm thinking about changing my nickname to Neox from the ScubaBoard Matrix :cool2:. "There is no spoon..." "I am not getting bent..."

Easy to say when you're not even diving normal trimix :mooner:

He is checking with DAN.

Heh-heh!

One episode (2008) with acute/worsening symptoms upon presentation, clinically diagnosed and treated with HBOT [Hyperbaric Oxygen Therapy]:
http://www.scubaboard.com/forums/near-misses-lessons-learned/264517-type-i-bends-hit-chuuk.html

One time suffering from the chokes after 30/30 triox repetitive dives as mentioned above with resolution of symptoms (shortness-of-breath); did not seek or require medical treatment (2006).

So officially two medical HBOT table 6 treatments stemming from Chuuk incident above in 2008, together with six to eight "practice sessions" to 2 ATA pressure, simulating patient treatment on dive accident victims, as part of the Catalina Hyperbaric Chamber Volunteer Crew Training Regimen since then.
