Hi all đ. I was diagnosed in 2018 with Interstatial Pulmonary Fibrosis and COPD. Have been on 24/7 oxygen since. Am taking Esbriet for IPF, unable to tolerate OFEV. Not doing anything for COPD and wonder what to do? What about the ânumbersâ, what is that? I have a home concentrated with a 50 ft air tube, which is fantastic although irritating, and a portable backpack concentrated Activox, which is heavy for me but it works great. I go any where I want, even on a20 day cruise this past January with the family. Anybody have any suggestions?
