Oxygen and Breathing
How long can a person breathe in an atmosphere without
oxygen (say, pure nitrogen or argon) and still recover? What would be the
symptoms of less than full recovery? Do you have a reference to this
It doesn't take long for somebody to become unconscious under such
conditions. The first organ to suffer under conditions of oxygen
deprivation is the central nervous system... less than full recovery would
be brain damage. A textbook on emergency medicine should have information
about this topic.
