While that sounds logical, just saying it is not going to satisfy others
unless more concrete proof is posted to show that the average compressed

prior to refilling.

Actually all that is needed is to know that the FDA and other
agencies require certain additional tests to be performed and paperwork
filled out before something can be called medical oxygen. Under these
laws you cannot knowingly sell non-medical Oxygen for medical purposes
and the insurance company sure as heck won't pay for it.
If the question is can someone go to the local Ox-shop, tell the
person they want welding oxygen, take it home and use it for medical,
yeah. Just like you can use medications for off-label uses, but you take
on extra risks by doing that.
