It is a question of how this child is going to die. As I said very clearly in my earlier post (but I'll repeat it anyway) . . . If the ventilator is turned off and the child dies, then the child has effectively died of whatever medical condition caused his hospitalization in the first place. If the child were breathing on his own and the feeding tube was removed, then starvation/dehydration --
not the condition that resulted in his hospitalization -- would be the cause of death.
This might sound very subtle, but it represents a huge distinction in medical ethics.
