Ed thought he would be going home today (day5), but he is SOB when he walks. Apparently, breathing has to be about "93" unaided and when he walks it goes to "88" and so he is back on the oxygen. The deep breathing exercises are painful. Maybe, they have to up his pain killers? He doesn't want that because it makes him "dopier" than he normally is. We are hoping for tomorrow to go home, but I also don't want to rush it.
