What happens if the brain loses its blood and oxygen supply?
Brain cells die when the brain is deprived of blood and oxygen. This can cause major brain injury. The brain may lose blood and oxygen supplies as a result of a near drowning, choking, heart-stopping electrical shock or respiratory problems. When the brain is deprived of oxygen, it is known as an anoxic brain injury. This type of injury is different from a traumatic brain injury (TBI), which generally results in swelling or bruising of the brain.
