I'm trying to help my dad, who is in a nursing home in California, but I live in Oregon. I don't have money or power of attorney for him. Any advice?

I am so lost and need help. My dad had at least 3 strokes and is in a nursing home in Bakersfield. I live in Oregon. He has nobody to see him or help him. I would like to get him to Oregon but I can't seem to find out how. He can not talk or walk or use the bathroom without help and I don't have money. He gets a small amount from social security and he has Medicare, but I do not know how long he gets it. I cannot find out anything because I'm not power of attorney. I went to legal aid to ask about power of attorney but they could not help me. The place he is at now sent me a bill for 10 grand. I was able to apply for MediCal but won't know for 45 days if he can get it and I don't know if the place he is at now will keep him there until then. I'm overwhelmed and I don't know where to go next. Any advise could be good.
