I like the fact most COPD pts know they have the disease well before they need oxygen therapy anyway. Like this guy, they live with it and understand it. He is on 3 L/M at rest and 5 L/M with exertion. I doubt I would have trouble giving him more if he need an Oxygen burst. So both are wrong and COPD is really individualized. Thanks for all the articles. All are a good read. http://www.okanefamily.net/living_with_copd.htm
