Over-saturation?

Postby HSS » Thu Mar 04, 2010 3:22 am

From what I understand, human blood can only contain a certain amount of CO2 (forget the exact number). But I was wondering if "over-saturation" existed. I know that saturation basically means that it contains all that is physically possible (I mean, you can't just add extra atoms to a compound at free will because not only would it completely change the composition, but sometimes it just isn't possible to do so).

If over-saturation is possible (please explain why or why it wouldn't be), what would be the effects that the CO2 would have on the blood? Would the over-saturation levels be so significant that it could almost make the blood toxic?
And what would lead to over-saturation? A thin arterial wall, or something to do with the lungs?

Thanks so much, I'm not in a rush for an answer, it's just that my teacher isn't really open to questions that aren't directly affiliated to what she's teaching.

I'm not sure what you mean by over-saturation, but the cause would be lack of oxygen. The effect would be suffication. CO2 is supposed to come back out of the blood by respiration, if it doesn't then oxygen can't attach it's self to blood cells, your body can't function with out oxidation and you DIE.

Saturation is basically the point at which the solution of a substance can't dissolve any more of that substance. So if the saturation of CO2 in blood is at 100%, is it possible in any case for it to be over 100%? I know that technically, +100 doesn't really exist, but I was wondering if due to anomalies or any other factors, it could be made possible.
