Vdaughter,
He needs to go to the emergency room. If he is bleeding that much. It will start to clot, and he will be unable to pee at all. I do know this from personal experience as my husband waited and then went to the emergency room due to the fact he couldn't urinate, and was in extreme pain, after all was said and done he lost 3 units of blood (the body only has 8 ) and was in surgery 2x's. It is possible to bleed to death, and that is not necessary in 2007. It will not stop on its own unfortunately. . He needs medical attention regardless of the decisions not to go further with the treatment, they can still treat symptoms, or eliviate pain. He should be monitored as he is dying too. There is no need to suffer like that. Take him to the ER, and talk to the Social Services Dept. they will help set up hospice, either at home, or in a facility depending on his and your family's needs.
God Bless You, I know how hard this is. I put my Dad in Hospice 2 yrs. ago Sept. He also had COPD, and ended up on a forced breathing machine before we put him there. They are a very unique group of people (almost like angels on earth) they will help your father during this time, and make sure he isn't in any pain, but they will also help your family tremendously. I still have a lady that calls to see how I am 2 yrs. after my father passed.
If you need anything please PM me. I would be happy to help.
Karen
