Hypoxia generically means a low level of oxygen. In different contexts it may refer to:

In the body:

  • $Hypoxia$, the reduction of oxygen in tissues below levels which are considered to be normal.
  • $Hypoxaemia$, the reduction of oxygen specifically in the blood.
  • Anoxia the extreme form of hypoxia where there is no oxygen present.
  • Ischemia is a medical term for hypoxia where there is a restriction in blood supply, generally due to factors in the blood vessels. Also ischaemia or ischæmia.
  • Hyperoxia, the condition opposite to hypoxia, is an excess of oxygen in body tissues or a higher than normal partial pressure of oxygen.

In the environment:

  • $Environmental hypoxia at high altitudes$ the reduced partial pressure of oxygen available to organisms at high altitude leads to hypoxia.
  • $Environmental hypoxia in sea water$ or oxygen depletion, a reduced concentration of dissolved oxygen in a water body leading to stress and death in aquatic organisms.
  • $Hypoxic zones, ordead zones$, are hypoxic areas in the world's oceans.
  • Anoxic sea water is a condition where there is an abnormally low level of oxygen in the sea.
  • The oxygen minimum zone is the depth in the sea at which the disolved oxygen level is lowest, or most hypoxic.

Measurements of hypoxia

  • Oxygen saturation is a relative measure of the amount of oxygen that is dissolved or carried in a given medium and is therefore a measure of hypoxia or hypoxic conditions.
