I Am Asking A Question For A Friend. Her Brother

I am asking a question for a friend. Her brother is dying from Cirrhossis of the liver. She is in her 60s herself and doesn't use the internet. She wanted me to tell her what signs to look for in the finally stages. She just wants to be able to prepare for what is about to happen to him. He is already jandice and has been extremly blotted and in a lot of pian. Can you tell me in simple terms what I can tell he to expect.
