Normoxia vs. Hypoxia — What's the Difference?

(physiology) The condition of having a normal level of oxygen

Deficiency in the amount of oxygen reaching body tissues.

Depletion of dissolved oxygen in aquatic environments to levels that are detrimental or fatal to aerobic organisms, often caused by eutrophication.

(pathology) A condition in which tissues (especially the blood) are deprived of an adequate supply of oxygen; anoxia

A reduced concentration of dissolved oxygen in an aquatic environment.

A very strong drive resulting from a deficiency of available oxygen in the blood and bodily tissues (short of anoxia)
