I studied brain death a lot last year. I think it’s possible to make an error in the determination of brain death. It’s rare though. Usually, they have two doctors make the determination a specified period of time apart. The tests they do are outlined in youtube videos.
I followed the Israel Stinson case and was really swept up in the emotions surrounding it. While one can say he had some life left in him, it was very very little. Essentially, he was kaput. That’s the best word I can use.
It’s different when somebody is in a coma. It’s also different if somebody is in a vegetative state. But if a person can’t breathe on his own and needs a ventilator, AND displays all the signs of brain death, I would say it’s best to let them go.
If you had a clock that was right two times a day, but otherwise not working, it really is best to admit that your clock is kaput and can’t function as a clock. Yes, Israel Stinson had some reactions, and I don’t agree with the doctors who think it’s all reflexes, for it’s not, but we’re talking such a low low level of liveliness. It takes a lot of medical expertise to keep people on a ventilator; in some cases the patient can get a tracheostomy, but the question is, “Is this person even aware he’s alive?”
