Brain death is a medical sham that allows the transplant industry to harvest unpaired essential organs from patients who aren't really dead. Read about it here. If any medical professional asks to do the "apnea test" on your loved one whose been brain damaged in an accident, ask what benefit there is to the patient. The apnea test is performed by turning off the ventilator for up to ten minutes to see if the patient will breathe on his own. It's the prelude to declaring the patient "brain dead" at which point the medical team turns the ventilator back on to keep the organs fresh for harvesting. There is absolutely NO MEDICAL BENEFIT to the patient from the apnea test. Rather it represents another assault on the patient guaranteeing his condition is irreversible. Then they put the pressure on the family to donate the organs.
God help us!
