Question

What is the difference between High Flying Oxygen and medical oxygen?

Answer 1

in addition to "dry" O2 -  the emergency O2 uses a chemical reaction to create the O2, it isn't stored in a tank.  it is made to last long enough to get the plane down from altitude

Answer 2

theres no difference

Answer 3

The technical standards state that aviators breathing oxygen (ABO) must be moisture free which is the critical difference between ABO and medical oxygen.

Answer 4

high flying- as in the sky

medical oxygen- oxygen they use that is compacted in the oxygen tanks that people use.

Answer 5

Both answers above me are correct! Good work guys

Answer 6

Aviation oxygen used for high altitudes MUST be moisture-free.  Any moisture in the O2 can cause aviation oxygen systems to freeze up due to the low temperatures involved.

Medical O2 typically has moisture added to prevent drying of the nasal and breathing passages.  Using medical O2 for flight would have catastrophic results when the systems froze up due to the added moisture.

Answer 7

oxygen is oxygen its whats added to it
