Wow....like reading The Abyss and Warhammer 40000 at the same time....pening(headache)...pening....any technical minded people can give explaination and comment.

very macabre science.

I think wikipedia explains it easier: http://en.wikipedia.org/wiki/Perfluorocarbon

Perfluorocarbons accelerate nitrogen washout after venous gas emboli. Success in the treatment of decompression sickness has been shown in rat, swine, hamster models. This treatment shows great potential as a future adjunctive therapy for decompression sickness in humans.


For divers, I guess the biggest advantage is PFC accelerates nitrogen washout when gas emboli occurs in the bloodstream. Imagine a giant nitrogen bubble get stuck in one of your veins... blood cannot flow through or worse, vein goes kaput. If PFC can accelerate nitrogen washout ("dissolve" the nitrogen bubble), then it can become a lifesafer for DCS.

If you look into the references, firstly the suggested treatment was meant to be adjunctive when hyperbaric treatment was delayed or unavailable, not mainstay. Also note that in the treatment arm there was significant morbidity/mortality albeit less than control group. For obvious ethical reasons there were no human trials recorded. Don't hold your breath! The gold standard of hyperbaric/O2 treatment IMO will remain for a while yet.

The referances suggests that administering PFC coupled with breathing O2 will increase the chances of survival but for how long?........

I think this treatment would be most helpful when enroute to a chamber far away........
