Brain Death
Most organ donors are people who suffer from head injuries that result in brain death. These head injuries may include a stroke, trauma after an accident, or brain tumor that has not spread to other parts of the body. Brain death occurs when blood and oxygen cannot flow to the brain while the heart is still beating providing blood and oxygen to other parts of the body. Patients with brain death usually require a ventilator or breathing machine to bring oxygen into the lungs. In brain death the organs remain functional and can be used for transplantation after a physician declares the patient brain dead. Because of the potential for conflict of interest, this physician may not be part of a transplant team.
