Definition of Cerebral arterial gas embolism (CAGE)

Cerebral arterial gas embolism (CAGE): Gas bubbles traveling and lodging (embolizing) in the arteries that supply the brain with blood (and oxygen).

Gas emboli in the brain can lead to a stroke-like condition with disorientation, difficulty walking and talking, coma, and death.

For example, even a single breath of helium can cause CAGE.
