My husband aged 74 was diagnosed with severe emphysema. He has been on oxygen 24/7 for 3 years now. He stays active and most days feels good. But he is so concerned about his future. We don't any of us know how this life will end but he can't really find anything that tells when that will be .Or how. He feels like there are things he needs to take care of before he isn't able to. He recently had a lung capacity test and will get the results of that this next week. Can the Doctor tell him anything as far as how bad he is? I read on here about people who have had this disease for a long time. But not necessarily severe.
