n.
a condition in which the tissues of the body receive inadequate amounts of oxygen. This may result from low atmospheric pressure at high altitudes; a shortage of circulating blood, red blood cells, or haemoglobin; or disordered blood flow, such as occurs in heart failure. It can also result from insufficient oxygen reaching the blood in the lungs due to poor breathing movements or because disease, such as pneumonia, is reducing the effective surface area of lung tissue. See also hypoxia.
anoxic adj.

anox·ia (ə-nokґse-ə) a total lack of oxygen; often used interchangeably with hypoxia to mean a reduced supply of oxygen to the tissues. anoxic adj
