Question:
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 topic?



Replies:
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.
