Carson is infected/influenced by something that makes he see what he thinks should be, not what is. It also infects those he is around/in contact with. He thinks John is hurt and should be on a ventalitor so he has him restrained and put on one. John keeps fighting it because he doesn't actually need it. Someone eventually figures out what is going on and gets John free.
Hopefully someone has better luck than me and can find it soon, it's been driving me crazy for weeks!
