My brother in law is in the hospital, both feet are purple with blisters appearing, his hands are starting to turn purple also. His heart is at 20% capacity and lungs less. Surgeons can t operate because he wouldn t survive surgery. He is hooked to a morphine drip through his stomach. I know that he will pass away, but I am concerned for my nieces and nephews who are with him 24hrs. They are exhausted and all have small children. I want to talk to them about going home for a rest, but I don t want to do that if his death is imminent. What is the duration of his life expectancy. He is heavily sedated and not aware of their presence
