You could put it that way, I suppose, but it's hardly the same thing as being hooked up to a machine. You could feed a person through an NG tube just by manually pouring the nutrients into a funnel. Her parents have been more than willing to take care of her that way.
Has she eaten orally since her collapse? Don't you suppose that nursing staff have at least tried ice cream or baby food in 16 years?
I don't know the full details of her care. I only know that her husband has refused (formal) swallowing evaluations on her. What the nurses might have done off the side and off the record is anyone's guess.
Well, except for the sworn affidavits of the nurses.
