Hypoxia Explained

Hypoxia means a lower than normal level of oxygen, and may refer to:

Reduced or insufficient oxygen

Hypoxia (environmental), abnormally low oxygen content of a specific environment
- Hypoxia in fish, responses of fish to hypoxia
Hypoxia (medical), abnormally low level of oxygen in the tissues
- Autoerotic hypoxia or erotic asphyxiation, intentional restriction of oxygen to the brain for sexual arousal
- Cerebral hypoxia, a reduced supply of oxygen to the brain
- Diffusion hypoxia or Fink effect, a factor that influences the partial pressure of oxygen within the pulmonary alveoli
- Histotoxic hypoxia, the inability of cells to take up or use oxygen from the bloodstream
- Anemic hypoxia, Blood is not able to take sufficient amount of oxygen due to Anemia
  - - Hypoxemic hypoxia or hypoxemia, a deficiency of oxygen in arterial blood
- Hypoxic hypoxia, a result of insufficient oxygen available to the lungs
- Intrauterine hypoxia, when a fetus is deprived of an adequate supply of oxygen
- Generalized hypoxia is hypoxia distributed amongst all tissues
- Latent hypoxia is artificially raised oxygen concentration in the blood due to high ambient pressure and will reduce when the pressure is reduced to normal, associated with freediving blackout.
- Pseudohypoxia, increased cytosolic ratio of free NADH to NAD⁺ in cells
- Tumor hypoxia, the situation where tumor cells have been deprived of oxygen
