Lets not get dioxide and monoxide confused now!
The difference between the two is that since the body does not react to increased levels of CO in blood, you will pass out peacefully (same happens when O2 decreases below normal levels).

The body will fight rising CO2 levels by increasing respiratory frequency (and the horrible "I can't breathe feeling") but the end result will be the same.

A 40'000 ppm concentration is classified as an immediate threat to life (for the math inclined people, that's 4% by volume). Maximum short term exposure is 30'000 ppm and average safety limit 5'000 ppm.
