Cerebral hypoxia refers to the largest parts of the brain, called the cerebral hemispheres. However, the term is often used to refer to a lack of oxygen supply to the entire brain. In cerebral hypoxia, sometimes only the oxygen supply is interrupted. Brain cells are extremely sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.

You're not a native speaker-but I am, and I don't think that is a very appropriate usage. Having said that, I think the most likely synonym in your contexct is simply irrelevant (which is not exactly the sense in which the expression out of context is normally used). â FumbleFingers Aug 4 '14 at 16:53.
