Such a mean old man or??

Yes Pulmo rehab is a good thing and has helped me a lot. It's a bit expensive with or without insurance so you would tend to think that not only would they have the proper apparatus to exercise on but enough oxygen concentrators as well. Oh I'm sorry sir but this old lady needs to plug into this concentrator, ok that's fine, which one would you like me to plug into? Ah, there are none available at the moment, oh, do you have a special room that I can go sit in to just plain breathe? No sir, you would be kind enough to call 911 for me when I pass out for lack of O2. I get off the treadmill in the middle of my workout breathing heavy and the RT unplugs me and says the old lady needs oxygen. Am I a mean old man or is there something wrong with this picture.
