**[Hypoxia](/source/Asphyxia)** means a lower than normal level of oxygen, and may refer to:

## Reduced or insufficient oxygen

- [Hypoxia (environmental)](/source/Hypoxia_(environmental)), abnormally low oxygen content of a specific environment - [Hypoxia in fish](/source/Hypoxia_in_fish), responses of fish to hypoxia
- [Hypoxia (medical)](/source/Hypoxia_(medical)), abnormally low level of oxygen in the tissues - [Autoerotic hypoxia](/source/Autoerotic_hypoxia) or erotic asphyxiation, intentional restriction of oxygen to the brain for sexual arousal - [Cerebral hypoxia](/source/Cerebral_hypoxia), a reduced supply of oxygen to the brain - [Diffusion hypoxia](/source/Diffusion_hypoxia) or Fink effect, a factor that influences the partial pressure of oxygen within the pulmonary alveoli - [Histotoxic hypoxia](/source/Histotoxic_hypoxia), the inability of cells to take up or use oxygen from the bloodstream - [Anemic hypoxia](/source/Anemic_hypoxia), Blood is not able to take sufficient amount of oxygen due to Anemia - [Hypoxemic hypoxia](/source/Hypoxemic_hypoxia) or hypoxemia, a deficiency of oxygen in arterial blood - [Hypoxic hypoxia](/source/Hypoxic_hypoxia), a result of insufficient oxygen available to the lungs - [Intrauterine hypoxia](/source/Intrauterine_hypoxia), when a fetus is deprived of an adequate supply of oxygen - [Generalized hypoxia](/source/Generalized_hypoxia) is hypoxia distributed amongst all tissues - [Latent hypoxia](/source/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](/source/Pseudohypoxia), increased cytosolic ratio of free NADH to NAD+ in cells - [Tumor hypoxia](/source/Tumor_hypoxia), the situation where tumor cells have been deprived of oxygen
