perche:Ok, but this has nothing to do with the effect of CO during the dive. And PaO2 is normal, 1/2 life HbCO is 320min for FIO2=21%, ppO2 increases with depth, no more smoke inhalation during the dive ....
is there any significant effect from smoke inhalation?
I'm waiting for a comment from Dr Deco
Sorry not Dr. Deco, but yes there are significant effects from smoke inhalation. As I stated before the negative effects on your lungs are fairly significant. As far as cigars go, I will say that the damage is likely to be far less than smokeing cigarettes (such as I do).
As far as nicotine goes (which all tobacco users get in their bloodstream) it acts as a vasoconstrictor, lessing peripheral blood flow. Leading to a higher susceptabilty of hypothermia. And now that I think about it more than likely DCS as well, but that's just supposition.
