Please, please help me. I need answers desperately and quickly?

I was hoping that someone could please help me. One of my family members, who we are all very close to is very, very sick.. He is 60 years old and smoked his entire life. Last week, he went into respiratory failure and has been on a ventilator and sedated ever since. They said that he has emphysema, pneumonia, possibly a pulmonary embolism and he definitely has MRSA. Tomorrow they are probably going to give him a tracheotomy instead of keep him on the ventilator. I know he is extremely sick but I am trying to see if anyone know whether or not he will be ok? I am trying to stay strong and keep my faith that he will be ok but I also need to stay with reality. Thank you to anyone who takes the time to answer, it means a lot to me.
