Cerebral hypoxia

"Reducing blood flow to those parts of her brain will place her in a state of cerebral hypoxia."
"What will that do?"
"Render her essentially brain dead, which makes no sense."

―Dr. Carson Beckett, Teyla Emmagan and Dr. Rodney McKay^[src]

Cerebral hypoxia is a condition in which the human brain is deprived of oxygen. Prolonged hypoxia causes neuronal cell death, which results in brain injury and can lead to the individual becoming brain dead. Oxygen deprivation can be caused due to disruption in blood flow or reduced oxygen availability.

History[]

In 2006, Dr. Elizabeth Weir was infested by Asuran nanites and comatose, after being infected by Niam. As a battle of wills took place in her mind, a significant amount of nanites relocated into her arteries that supplied blood flow to the higher functions of her brain. Dr. Carson Beckett put her on 100% oxygen and norepinephrine, five mics per minute. He informed AR-1 that reducing blood flow in those parts of her brain would put her in a state of cerebral hypoxia. Dr. Rodney McKay clarified to Teyla Emmagan that it would render her essentially brain dead. Lt. Colonel John Sheppard came to the conclusion that the nanites were doing it to try to take control of her body with an attempt to replace her consciousness. (SGA: "The Real World")
