The physiology of human oxygen requirements is well known and documented.
It has almost nothing to do with your physical condition or “toughness”. The
numbers used in this manual apply to a healthy non-smoker in good physical
condition, except where noted. Human oxygen requirements have no “macho”
factor. Modern oxygen equipment is comfortable and relatively inexpensive. If
flying a pressurized IV, consult oxygen equipment manufacturers and purchase
