Again, that is suffocation (lack of Oxygen) and not because you are 
breathing CO2 which is normally not considered poisonous, otherwise I 
agree with what you say.

It makes little difference once you are dead, but you can be 
resuscitated if removed from the lack of Oxygen, while CO poisoning 
requires treatment and specifically keeping the patient "still" rather 
than letting them exercise.  With enough CO poisoning, the patient may 
have reached the stage where giving them Oxygen won't even work.

With CO2 you simply have to get enough oxygen back into their system for 
a rapid recovery, unless they were Oxygen deprive long enough to have 
done brain damage.
