Brain dead patients do not breathe on their own and cannot breathe. If there is breathing, it is being assisted by a ventilator. A brain-dead patient who is still breathing on his or her own means that the diagnosis of brain death is faulty. A truly brain-dead patient has a complete loss of brain function that cannot be recovered, and the same respiratory center located in the medulla oblongata of the brain also loses function and stops working, and the patient is not breathing on his or her own, but the heart is still beating. Without the help of a ventilator, the brain-dead patient would die from cardiac arrest within minutes. Even with a ventilator to help with breathing, the vast majority of patients’ hearts will stop beating within a week. A diagnosis of brain death is the same as declaring a person dead with no resuscitation value, but with ventilator maintenance, useful organs can be donated to patients who need them before their hearts stop beating.
