The main difference between medical grade and industril grade is that
with medical grade the cylinders are evacuated (they pull a vacuum) to
eliminate the possibility of any contaminating gases.

This is another fine example of BS and strokery.
Aviators oxygen, I believe is checked to make sure it
has a low moister content for obvious reasons, but I'm not
an aviator so don' t take my word for this.
As far as industrial and medical oxygen is concerned
there is absolutely no deference between the two.
The cylinders are filled from the same liquid oxygen bank,
the difference is in the maintenance and handling of the tanks,
and believe me, I have seen industrial tanks in a lot
better shape than medical cylinders. This does not mean this is
always the case.
Oxygen is oxygen is oxygen. No deference other than what you
are breathing it out of, and impurities that can enter the tank during
transfer. This is why o2 should always be analyzed before using or
mixing.
