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.
Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy.The result of breathing elevated partial pressures of oxygen is hyperoxia, an excess of oxygen in body tissues.xygen toxicity is managed by reducing the exposure to elevated oxygen levels. Studies show that, in the long term, a robust recovery from most types of oxygen toxicity is possible.
