hypoxia n : a very strong drive resulting from a deficiency of available oxygen in the blood and bodily tissues (short of anoxia)
- A condition in which tissues are deprived of an adequate supply of oxygen.
Hypoxia literally means "a deficiency in oxygen." It can refer to:
(medical), a shortage of oxygen in the body. Hypoxaemia is the
reduction of oxygen specifically in the blood; anoxia is when there
is no oxygen available at all.
- Environmental hypoxia, a condition in high altitudes such as mountains where the reduced partial pressure of oxygen available leads to hypoxia.
- Ischemia, a restriction in blood supply (and therefore oxygen supply) to an organ or section of the body, generally due to constriction or blocking of blood vessels.
- Hypoxia (environmental) or oxygen depletion, a reduced concentration of dissolved oxygen in a water body leading to stress and death in aquatic organisms.
In popular culture
- Oxygen saturation, a relative measure of the oxygen dissolved or carried in a medium; a measure of the severity of hypoxic conditions.
- Oxygen toxicity (hyperoxia), the opposite condition of hypoxia, an excess of oxygen in body tissues.
- Time of Useful Consciousness, a measure of how quickly hypoxia renders a person incapable of normal thought.
- Respiratory Acidosis, a decrease in physiological pH due to hypoventilation or decrease in gas exchange by alveoli
hypoxia in German: Hypoxie
