Isn't CO₂ poisoning in humans supposed to cause a panic reaction which would serve as a defence? Why didn't that happen here?

- aYsY4dDQ2NrcNzA 10y agoI've never heard of this. Do you have a source? I recently learned that CO2 is toxic to human in large concentrations. It doesn't just displace oxygen in your lungs.

- gruturo 10y agoThere is normally still plenty of O2 left in the air, so you are conscious and panic when too much CO2 is around (actually, in your bloodstream rather than around). If a huge amount of CO2 displaces everything else quickly, there is suddenly no O2 at all and you just faint, then die.
- arrosenberg 10y agoThat's why CO2 poisoning is the humane way that lab specimens are put to sleep.
