My mother had her right upper and middle lobes removed 2 weeks ago today. She has emphysema/COPD and NTM, diagnosed 2013. She is still extremely weak and on home oxygen. Has anyone been through this or have a family member that has been through this? Did you have to stay on oxygen? What is your quality of life now? If a family member, did your loved one survive? My mother is very thin/low body weight and did not exercise prior to surgery and now she can barely walk two steps without gasping.
