January 29 - She is still improving, but we are still in the rehab home.  Incisions are fine, heart sounds fine, but still having trouble with fluid on the lungs. 40 mg Lasix/ day and oxygen 2 liters/min.  While she can function for a couple of hours off oxygen, her blood oxygen level then falls below 90%; they are keeping her on oxygen constantly to keep her energy level up for physical therapy, occupational therapy, and speech therapy. The idea seems to be that if they can build up muscles it will make her breathing stronger too. She is very much herself intellectually.
