I believe three doctors have declared her brain dead..when the brain no longer functions she is no longer there but by the grace of a machine pumping air into her body.
I'm surprise by your comment.
Something went wrong that caused this to happen..a healthy 13 year old girl going for a routine procedure doesn’t wake up, start vomiting blood, and then dies..someone screwed up here..this poor child is obviously brain dead but the hospital is in a huge rush to remove her from the machines..give the family time to grieve they were not expecting this when they took her to the hospital for this procedure
