How do some of you guys that need more than 5LPM fly. I'm on 4 LPM at home and my O2 provider set me up with a stationary concentrator that's capable of 5LPM. Then for going out they gave me some "D" and little m-6 tanks that the home concentrator can fill up while I'm using it or not. Nice to have some back up tanks, but don't use them much because I have my own POC. Now we're going on a small trip and my Pulmo tells me that I should be on 5LPM when in the air because a pressurised cabin is equivalent to 8000 ft. I talked to my O2 provider and they said I couldn't bring the home concentrator because it takes 120v and you can't use airline power. I said how are you going to provide me with oxygen while I'm away from home and on board the aircraft. We will supply you with a concentrator that is pluse dose and LPM on a pull behind cart. Have the battery charged when you go out and use it on pulse dose. When sleeping at night, plug it in and you'll be all set up. Don't put it on LPM when you go out because it will use up the battery real fast. They said my original prescription from my Pulmonologist is 4LPM so the one we are setting you up with go up to 4LPM. I told them that my Pulmo said I need 5LPM in flight. They told me that don't have any that go that high because they would run the battery out to fast. So how do I fly if mine only goes up to 4 LPM. I could have that on and then with another cannula up my nose I will turn on my on POC which will more than make up the difference. Is that how it's done? Why do the airlines care weather it's 5 or 2 or 10 LPM, can't they keep their nose out of it. Why can't I just go on board and let myself decide weather or not I want to use my POC or not. What a hassle. Gotta make something simple into a big deal. Paperwork, a note from a doctor like I'm a kid in school. No wonder some people don't go out. Even with my Inogen G3 and a pulse dose/LPM concentrator I might not be let on board because of their stupid head games. If they don't let me on I will either in up in the hospital or jail because I will be so upset and raise so much hell I will probably just pass out and they will call 911 or I will start throwing stuff and then metro gets me. Which is another question, are you allowed to keep your POC on you while in jail, how about charging it. I'm really a pretty nice man but by reading this you would probably say: " this guy is a nut case, glad I'm not like he is." We will know the 19th, weather it's travel, go back home, the hospital or the old jail house. I just about to the point that I don't really care what happens. Ok, I'll shut up, thanks for listening
