Do people now confuse CO and CO2 or maybe people do not know there can be more than one compound of two elements? (In all fairness I have forgotten which oxides of nitrogen are which).

That's like that joke, two scientists are in a Bar:

Scientist one says "I'll have some H2O", and gulps down the whole glass
Scientist two says "I'll have some H2O too", and gulps down the whole glass and dies.

Also, we need CO2:
Low carbon dioxide levels in our body lead to narrowing of the blood vessels that supply blood to the brain. This reduction in blood supply to the brain leads to symptoms like lightheadedness and tingling in the fingers. Severe hyperventilation can lead to loss of consciousness.
