Don't even think of using compressed air or Nitrox--neither will do you any good in a reduced pressure environment. Above 30K ft, even pure O2 is not enough--at that point you need to add positive pressure breathing in addition to O2 to even get close to normal partial pressure O2 in the blood.. Douglas W.
