Hypoxic brain injury (HBI) is a term used to describe a diffuse brain injury as a result of global, temporary loss of blood supply and oxygen. Hypoxic ischemic brain injury (HIBI) is now used to refer to damage due to interruptions in perfusion to the brain, usually due to cardiac arrest or profound hypotension.

Hypoxic brain injury (HBI) occurs when the brain does not get enough oxygen, which causes brain cells to die.

Hypoxic ischemic encephalopathy (HIE) is an umbrella term for a brain injury that happens before, during, or shortly after birth when oxygen or blood flow to the brain is reduced or stopped.

When oxygen levels drop to a dangerous level, brain cells begin to die. This can lead to an anoxia/hypoxia brain injury. Also called a cerebral hypoxia or hypoxic-anoxic injury (HAI), this condition can cause permanent cognitive problems and disabilities, and it can even be life-threatening.

Hypoxic-ischemic encephalopathy (HIE) is a brain injury that occurs when your brain doesn’t get enough blood and oxygen. This can permanently change how your brain functions.
