I am indeed a real doctor, triple board certified and one of my boards happens to be neurocritical care. This is a very sad and awful case. I am certain all involved are haunted by it. But yes, the heart can be kept alive indefinitely my ventilating the lungs. The lack of brain function confirm the death.
Thank you. That's what I wanted to know.
I did not mean to cast aspersions on your honesty - I was just stating the obvious, this being the internet we have no way of knowing a poster's claims (for example, I am not actually Don Rodrigo, chasing Moors around with my lance). That said - I fully agreed with your comments and appreciated them. It included important technical details.
