I am
sure that the doctors on this group can give the yay or nay, but I was lead
to believe that in medical use a humidifier is used between the bottle and the
patient.
As
for the difference between medical and dry breathing oxygen, I was speaking some
years ago to the LAME who looks after some of the RFDS aircraft. He would
top up both the pilots emergency system and the patients medical system
from the one bottle. I seem to recall he used medical oxygen for
both with no ill effects (either in practice or in
auditing!)

SWK Just
had a quick look at BOC medical gases.
Oxygen
impurities:
medical - moisture < 67 ppm (seems pretty dry to me, as far as
patients breathing it goes)
dry breathing - moisture < 7 ppm
(and strangely New Zealand oxygen <
15ppm)
(then
products/medical/medical gasses/oxygen)
