he barely has a few minutes left in this video before the breathing reflex is gone too, then he is totally dead. he was dead the moment this event happened. at least it was quick for him
I always wonder with stuff like this, seeing as they say there has to be no brain function for someone to be truly dead, is he still alive, because obviously there is some sort of function going on in the brain to control the breathing that is still happening.
The part of the central nervous system that regulates breathing is the brain stem so under the brain , in the dangly bit.
