question: My mother inlaw has final stage copd. The doctors gave her 2 months. It now over 3 mo nths and they are looking to send her home. We were told she would oxygen 24/7 that was a week ago. Today they said her blood oxgen is perfect and she no longer needs it. She went from bed ridden to moving around a bit. How could this be possible or was there a misdiogious. This is the second time in 2 years this had happen. Even the doctors cant explain it.
