I don't know the situation with your dad Mike but time stands still for no one. We know what is coming to us all one day yet it still shocks and causes mental turmoil when the medics take you to one side and quietly explain what you've been dreading about a loved one who is in their care in hospital. It can't be easy for the medics even though they will have to deal with these situations on a very regular if not a daily basis. I trust them and feel that they will have done their best for your dad. If it is the case that they are now talking end-of-life care they will want to continue to do their best for your dad for his remaining time. Please consider that he might be in the right place for this if it is so. They have the staff, the equipment and the medicine to make you dad as comfortable as possible - pressure pads/mattress, pain relief turning him in bed etc..
