RE: Is it OK to turn on an oxygen concentrator before my APAP machine?
MIL started on her O2 concentrator back in the late 1990's. I remember that it was a beast, it had wheels but with the shag carpet, it took two strong boys and a whole bunch of grunting to move it. I should hope with today's technology, they would be much quieter. I do not remember seeing portable concentrators back then. Everybody used portable O2 bottles (tanks).
