The CO2 in the bloodstream is generally the result of oxidation of organic compounds so more O2 in the blood also increases CO2 in the bloodstream indirectly.

You haven't confused Carbon Monoxide with Carbon Dioxide, have you?

CO2's not really particularly poisonous. It's about 0.4% in normal air, and it's about 4% in our exhaled breath.

Generally, in any rebreathing situation, it's oxygen deprivation that gets you, not excess CO2.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.

I give point to ed on this, seems that CO2 buildup can cause enormous problems. It may not act as a poison, but sure can make the system go way haywire leading to death, if only death by confusion.
