Answer Wiki. Breathing pure oxygen kills you because it destroys the normal gas balance with CO2 (carbon dioxide) in the lungs required for effective oxygenation on the cellular level. That's why some modern lifesaving applications prefer using Carbogen instead of pure Oxygen. Carbogen is a 95:5 mixture of O2 and CO2.
It definitely will kill you, but definitely not instantly. Nitrogen is not toxic at all under normal circumstances. We breath 78% nitrogen all day long and it doesn't harm us at all. But breathing pure nitrogen means we're not breathing oxygen, which means that we'll die of oxygen deprivation in a matter of minutes. But a pure nitrogen environment is particularly dangerous because it's odorless, tasteless and invisible. Moreover, if you're breathing nitrogen, you don't feel like you're suffocating.
