cerebral anoxia: a condition in which oxygen is deficient in brain tissue. This state, which is caused by circulatory failure, can exist for no more than 4 to 6 minutes before the onset of irreversible brain damage.

The term anoxia means a total depletion in the level of oxygen, an extreme form of hypoxia or "low oxygen". The terms anoxia and hypoxia are used in various contexts: Anoxic waters, sea water, fresh water or groundwater that are depleted of dissolved oxygen.

Anoxia is known as the absence of oxygen. Anoxia could be an environmental term, describing an environment that has no oxygen, such as anoxic waters or in space. Medically, anoxia describes the absence of oxygen with an emphasis on organs, muscle groups, or blood not getting sufficient oxygen.

The brain requires a constant flow of oxygen to function normally. A hypoxic-anoxic injury, also known as HAI, occurs when that flow is disrupted, essentially starving the brain and preventing it from performing vital biochemical processes. Hypoxic refers to a partial lack of oxygen; anoxic means a total lack.

Shirtsleeved, no radio, no oxygen and 45 degrees below zero outside, only the onset of anoxia encouraged descent. Times, Sunday Times () A long half-life of the tyrosyl radical during .

with lack of oxygen (anoxia). Fetal anoxia may occur from inadequate oxygenation of the mother, low maternal blood pressure, or abnormalities in the uterus, placenta, or umbilical cord that result in inadequate blood flow to the fetus. After birth, anoxia may result from blood loss, shock, or .

Mar 27,  · Cerebral hypoxia refers to a condition in which there is a decrease of oxygen supply to the brain even though there is adequate blood flow. 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.
