THANK YOU all for your information.
I dont know what questions to ask at this point.
I had always heard so much bad news about being on a vent - but glad to know they can do the trach if needed.
They do think he has some sort of infection setting in (temp is 100) and they are treating him for that and looking to see what the cause is.
He did have to go back in for a 2nd surgery 4 hours after the lobe removal because of bleeding, so he did loose a lot of blood.
I am trying to be positive, but it is still very scary.
