Guest guest Posted July 26, 2009 Report Share Posted July 26, 2009 It is true that astronauts have used 100% oxygen in a hypobaric environment. 75% oxygen in an normobaric environment will cause a delayed death due to inflammation of the lungs. In a hyperbaric chamber 100% oxygen can cause convulsions and death in minutes. Source: " Oxygen: The Molecule that made the World " Nick Lane. Oxford University Press. Carbogen (95% oxygen with 5% carbon dioxide) is a radiation sensitizer. Quote Link to comment Share on other sites More sharing options...
