If it were my family member, I would get him out of that hospital, by force if necessary.
How does that work — a ventilator weighs a couple hundred pounds, the patient is probably not able to assist in movement — the hospital bed weighs several hundreds of pounds, oh, and if you disconnect the vent for a short time the patient would die.
It really is amazing the things some people say without thinking about it.
Once in, and vented….they’re trapped 😩
Short of that, it takes a really strong willed (persistent) person to advocate for them, without having access to them.
