So a number of years ago when the Dr. prescribed me oxygen they gave me the tanks, but they also gave me an O2 concentrator. Years later I'm still lugging that thing around through about 10 moves. The thing is heavy! But anyways, I'm going through a cycle and I haven't been to a doctor in my new city and haven't got a script for O2, but I still have my concentrator. Low and behold - it works pretty good surprisingly even at a max lpm of maybe 10 or 12 according to the meter. Do they make concentrators with a higher lpm? This one is knocking them out just fine, but feel an even higher lpm would knock them out even faster! This model is an integra. The plus side to a concentrator is no refills...it just does it's thing.
Thanks for anyone's response.
