Definition


Anoxia indicates a drop in the quantity of oxygen distributed by the blood to the tissues. It results in anoxhemia, which is a drop in the quantity of oxygen present in the blood. Anoxia can be caused by heart failure, acute respiratory disease, or anemia, among others. Affecting the skin and mucus membrane, anoxia provokes cyanosis, meaning a bluish-purple discoloration. When anoxia affects the brain, it can be tragic, the brain being unable to support a lack of oxygen for long; the consequences range from a loss of consciousness to coma, sometimes irreversible, and the affects can be serious. To treat anoxia, a diagnosis of the cause must be established, and the cause must be treated.
