This is reponding to Gingermarie asking about getting rid of oxygen. My rehab leader told me that most people don't get off oxygen unless they get new lungs!!! ---- but some do. I have learned be careful to never say never! The better shape you are in the better you do and then those more in shape muscles need less o2. It all depends on the person. sometimes i see them cutting people back on the flow of oxygen they need in exercise class. I hope you do great in rehab, Ginger. Glad to have you aboard here!!!!!
