Tami, I can't speak to the medical parts of your question, but I can address the personal parts. When my 84 yr. old Mom broke her hip late one night, she lay on the floor until the following morning before calling us because she did not want to wake anyone up.[She was one tough cookie]. But after surgery and very painful rehab that wasn't working and a continuous stay of 65 days in the hospital, she looked me in the eye and said she had had enough. I thought that meant she wanted to go home, but she fooled me. The next morning she was gone. I don't know how old your Mother is, but I do know that when you get to her bedside, you will need to listen hard to her wishes and try to balance them with what her doctors are telling everyone involved.It's not going to be easy. You will have support here. Amy
