| 5-5. ANOXIC BRAIN INJURY Anoxic brain injury is injury to the brain from lack of oxygen (from cardiac arrest, choking, or drowning). Spasms develop in small arteries if the brain goes without oxygen for more than 4 to 6 minutes. Blood flow does not reach the cerebral cortex. The level of brain damage is based on the length of anoxia (lack of oxygen). |
