Update on my Mom

My mom has been put on a ventilator and is being sedated. She began coughing blood last night and could not breath with the machine she was on. She is also being given amnesia medicine so that if/when she is taken off of the ventilator she won't remember being on it. The doctors are still talking positively, of course they will until there is literally nothing else they can do. So at this point it is a waiting game. They still have not biopsied her lungs and still do not know what is truly going on. They are putting off the biopsy because it is surgery and is a great risk.
