Grannie - trust me - I'm a doctor... (joke! - the "trust me" bit at least)
That first link is discussing laser surgery in the lungs - nothing to do with "injecting" air at all. And the second one is describing a paediatric cardiac surgery post-op case. They comment, as did I, on the fact that it is rare. And the situation was exactly what I described when I said that cardiac surgery is one area where air has to be evacuated from the system at the time of surgery. Carotid surgery is another.
Neither of those links describes "injecting air" or negates the info I posted. And yes, I do know what I'm talking about.... Both of those situations are ones that I have spent many, many years doing myself.
While I'm more than happy to have "robust" discussions on anything, there would seem to be little point in having verified professionals on here, if their posts - especially ones regarding facts - are not even believed and people then try to "prove" them wrong. I'm not trying to say that everything I may post is never wrong - I post on other aspects of the case that have no more "cred" than anyone else does. But when it comes to posts on facts in my area of expertise, then if someone wants to argue the points, that would seem to be a bit presumptuous. Do you really think I would post something in my area of expertise that I wasn't certain was correct? If you went to see a specialist and they gave you some information - would you argue and try to tell them they were wrong? Again - don't get me wrong - I'm all for inquiring minds and skepticism. But isn't that why I had to prove my credentials before my membership here was approved? Please give me some credit for knowing what I'm talking about.
And let me reiterate - I do believe that GBC is looking more and more like the guilty party, on the evidence we have. And I'm not trying to steer people's thoughts away from that - but just to keep minds open that there COULD - just maybe - be another explanation for the events. Highly unlikely, as I've said - but possible.
