My sympathies are with you and yours, Poppagator. I don't know if your MD is combining treatment with other known therapies or if it is experimental it may have binds upon it so as to not skew the results. Which ever way it goes I wish your wife the best.

The welding shop had a large cage where we started the oxygen bottles and quiet a few O2 patients would come in and buy O2 and swap bottles, sometimes the big 5 ft' tall ones. We bought our O2 from a gas processing plant in Bakersfield. Our family Dr told us that medical and welding all came from that same plant and there was absolutely no difference. The sad thing is that many of the customers used the product for only a short period of time. This was in the 60's and early 70's. They were apparently buying short reprieves from their ailments. If you are on O2 for the long term I would imagine that something pretty serious and irreparable has happened. I had an Uncle with a weird blood condition that made oxygenation very difficult. He lived about 5 years on O2 then passed on. He would not have lived 4 months beyond diagnosis without O2.
