@ethanmcconkey , I was just told today that the Pulm. Dr. wants me to try the trilogy machine to help blow off my carbon dioxide in my severe COPD/ ILD Respiratory Bronchiolitis. We are pretty much maxed out on medications and nebulizer meds. I never heard of this machine and am doing some research on it. I have seen CPap and Bipap machines, but this is new to me. Is this new machine a lot better than those? It is more beneficial or does it just depend on your diagnosis? I am already on O2 24-7 and have "flare ups" way too often now. Also have several different other problems such as an ASD, and PH. Thank you for any information you may give me.
