What is Anoxia, Hypoxia?
"Drowning, strangling, choking, suffocation, cardiac arrest, head trauma, carbon monoxide poisoning, and complications of general anesthesia can create conditions that can lead to cerebral hypoxia.
Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination.
Recovery depends on how long the brain has been deprived of oxygen and how much brain damage has occurred."
