Naughton, you are a complete neophyte and you are wasting everyone's time
here regurgitating nonsense that you  learned in your PADI class or in your
DAN magazine.  The fact is that Bennett has been painfully slow in
acknowledging reality and has had to be dragged kicking and screaming into
recognition of or admission of the truth with this stuff, his track record
at DAN is a disgrace in this regard ( little items like PFO that he has
fought to downplay until very recently), and what he or anyone else wants to
publish to sooth the feelings of the hordes of people who should not be
diving at all in order to satisfy his true client ( the dive industry) is of
no  interest to this list of people who are interested in tech diving are
real information. We don't need you to read us the bullshit that is fed to
the novice divers our there. Look at the name of the list, you driveling
idiot, and take your naive nonsense over to rec scuba where you will find
plenty of people who, like you, do not know any better.

Venous bubbles do not mean bent. We test for these all the time at WKPP
under the guidance of Navy doctors and Duke University and have done so for
many years, way before you read your first PADI booklet.

Really, shut the hell up if you don't know what you are talking about - you
look like a complete ass spewing out page one of the Misinformation
Handbook. You are 0 for 3 now on posts.

You might also want to not post private messages to this list, you flaming
asshole. In fact, you might was well not bother posting anything at all. You
have nothing to offer but petty nonsense and naive misinformation. You do
not belong here. You are disrupting the entire list with your stupidity. Go
learn about these things so that some of this will mean something to you,
and then we will not have to suffer with your idiocy clogging up the list.

Errmm... no, and I haven't claimed to have.

Not personnally. How, apart from being a leader for you to name drop, is
this relevant?

So are you saying that once someone is bent then there is no point in
attempting treatment?

I have sent this in a mail that has yet to appear on the list, but are these
venous bubbles? Could they not have been formed directly from gas in the
divers mask?

I too have learned from him. I reiterate that I am in no way challenging his
deco procedures.

Did he attended medical school? BTW I am  not trying not to be provocative.

I thought the WKPP acted as test-ish subjects-ish?

Not much. I don't know. What is the relevence of whether he dives or not?

As I have already said, I am not challenging G's decompression strategy - I
am not in the position to do that, just his rubbishing of Dr Bennetts study
based on the information contained in one paragraph written by a newspaper
journalist.

Your point being? They have loads of experience at DCI avoidence.

The relevence being that Dr Bennett has studied it and concluded that
subjects with 20-30 bubbles in the tear film of their eyes also had DCI and
those with 2-3 did not. G & the WKPP, AFAIK, have not studied this, so how
can G justify his statement that it is bullshit - but I guess that you
cannot answer that John.

I think that you are looking at this from the wrong angle. I don't believe
that Dr Bennett even implies that these bubbles are the cause or part of the
damaging part of DCI, there are simply 20-30 bubbles with subjects with DCI
and 2-3 with subjects without, therefore, the possiblity exists for an easy
test.
