My mother is in her last stages of alzheimers. She forgets to swallow. her lungs are infiltrated. When she used to eat she would choke on everything they give her. While she was aware she always told me that she didn't want to be put in any kind of tubes or anything that would delay her death. My mother is in a nursing home they have her with iv and a part of me is having a hard time with this. I was just wondering how long can she live with just iv. She has been with the iv since december 30.
