Hi all. I'm new to this community. I'm a member of the RA community (for myself) and I thought that I'd like to join this community (for my husband) to try to get more knowledgeable about his emphysema. My husband was diagnosed 17 years ago with his emphysema. Time has passed and we hadn't thought too much about it (head in sand syndrome ). Then in October 2015 the doctor put him on oxygen 24x7 and it really scared us. We had no idea he'd gotten so much worse. We just saw our GP this week and he's upped my husband's oxygen to 3 liters and has added another inhaler (Advair) to his already Combivent. While we were at the appointment, I asked the doctor what stage my husband was at. I was shocked when he said "the highest stage". How can that be??? What is entailed with being at stage 4? I'm so confused. He has never been hospitalized and he hasn't ever had a lung infection of any kind. The doctor had my husband walk around inside the building for a few minutes (while on oxygen) then took his readings. His readings went to 76. That's bad isn't it? My husband is so stoic, I never know when he's struggling. I'm frightened and I thought this would be a great safe place to share my fears and confusion. Thank you for listening, and if you have any insight I'd love to hear it.
