Anoxia happens when your body or brain completely loses its oxygen supply. Anoxia is usually a result of hypoxia. This means that a part of your body doesn't have enough oxygen. When your body is harmed by a lack of oxygen, it's called a hypoxic-anoxic injury.

What causes anoxia at birth?

Is anoxia a hypoxia?

Hypoxic refers to a partial lack of oxygen; anoxic means a total lack. In general, the more complete the deprivation, the more severe the harm to the brain and the greater the consequences.
