I am a caretaker for a man with severe emphases and stage 4 copd. He went to urgent care because he coughed so hard a d became breathless although he is on oxygen 24/7. At first it was diagnosed as pnamonia but later were told that it wasn t but was explained as the lung did not fully expand. He goes for a swallow test next week. My question is is this considered close to the e d of life for him?
