Hypoxia

Hypoxia is the lack of oxygen to any tissue or organ in the body. Cerebral hypoxia refers to a condition where there is a decrease of oxygen supply to the brain, even if there is normal blood flow.
Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination. Prolonged hypoxia can cause coma, seizures, and even brain death.

Hypoxia is a possible secondary complication that can develop over a period of hours to days after the initial TBI.
