Anoxia: Means a total depletion in

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: Anoxia is usually associated with hypoxia and is a severe form of hypoxia itself. Anoxia happens when your body fails to get any oxygen, and this might result in a hypoxic-anoxic injury. Read on to find out what is anoxia, its causes, symptoms, types, treatment, diagnosis and prognosis Anoxia can result from a number of conditions including cardiac arrest, carbon monoxide poisoning, stroke, brain injury, and complications due to anesthesia. It is thought that cells exposed to anoxia release glutamate. The CA1 cells of the hippocampus contain high concentrations of glutamate and are particularly vulnerable to subnormal oxygenation levels. Therefore, it appears that the action of glutamate on these cells is the putative mechanism mediating cell death in this region of the ... Anoxia occurs when the body or parts of the body do not receive oxygen—it's a life-threatening condition. The loss of oxygen can occur due to respiratory failure, cardiac arrest, traumatic brain injury, difficult delivery (affecting newborns), or other medical conditions.
