Are there any entry tech courses that include Trimix?

I think we are now picking at the 'vehicle to illustrate' rather than discussing the question if He is less forgiving than Nitrogen.

But let's turn it around and ask: why do some here not feel that helium is less forgiving?

Just being a devil's advocate here...

Its more forgiving because when it bubbles those bubbles are smaller.

Limeyx, The gentleman that I mentioned is conducting HUMAN trials on Navy Divers at NEDU in Panama City. I don't know if there are published papers or not. But that is what this guy does for a living. When he had something to say about decompression, I listened. Closely.

So he said it's OK to do a 90 min dive at 100 on 32% and not on He?
I don't doubt that you listened closely, but that doesn't do me much good if I am stuck out here in LA with no way of getting the same information.

Am I just supposed to "trust you" ?

Or would his insight also not be accepted, considered?

No, but if you google the name, and send the guy an email, he might answer your questions much as he answered mine.

And did anyone REALLY think that the profile I posted was being offered as "safe"? Come on guys we all know that profile is brutal. What I have taken away from speaking to divers and scientists who've done the research is that Helium tends to bubble out of the blood more quickly thus causing more potential for a type 1 hit. Since the bubbles also tend to be smaller, it seems it can be more likely to induce a type 2 hit. Notice I said "more likely", and not that it WILL. Of course this is a gross generalization.

David is an Australian born scientist and cave diver. However the US Navy invited him to the US to pursue research in this area. The WKPP invited him to work with them there. Those actions tend to tell me that some people highly value this mans work and his opinions. Of course, there are those who will listen to no one, and trust no one.

Dr Weinke spoke on this 2 years ago at the GUE conference. Did you go? I wanted to, but unfortunately ended up having to work.

Well, I would like something somewhat better than "It would seem" because often things that are "logical" or should be that way because of this and that factor, often aren't.

Well if you know any absolutes in decompression theory please publish them because the "experts" I have spoken with don't feel they have all the answers.

I dont recall mentioning the word "absolute" anywhere in relation to decompression, and I'd be the last person to do so.

You can still generate statistical evidence without having to show an absolute.

I thought the original point was: entry level deco, should it include He or not?

I say yes. If you can't dive He cause your ascents are questionable, then there's no reason to be doing deco at all.

Secondly, the last thing I want to be on a deco dive is impaired by narcosis. We all know that leads to bad decisions.

Get the training, develop your skills. Dive safe on the bottom and on the ascent.

Well, you posted the profile to make some kind of a point, only the profile really did not reinforce your statement (that somehow the dive was "OK" on 32% or "more OK" or "less bad" compared to 30/30)
