  • Title: [Aviation physiology].
    Author: Frank PW.
    Journal: Z Arztl Fortbild Qualitatssich; 1999 Oct; 93(7):476-9. PubMed ID: 10568247.
    Abstract:
    Aviation physiology should be known at least in parts by the physicians advising air travellers. Due to reducing atmospheric pressure at altitude gas volume in body cavities expands (Boyle's law). This might not be a problem during ascend since air can disappear easily through natural ways. However, air must return to body cavities during descend and a person with a cold may suffer from painful barotitis. Hypoxia is mostly due to a reduced pO2 in high altitude (Daltons's Law). This may be prevented by an aircraft cabin or supplemented oxygen. Decompression sickness is very rare in aviation but divers should comply to a dive free interval before flying.
