How can the brain be deprived of oxygen?

In: Human Anatomy [Edit categories]

Answer:

The brain becomes deprived of oxygen when the creature depending on the brain fails to breathe. This can be reversed with quick medical attention; otherwise everything shuts down and the creature dies.

Similarly if the air you are breathing is short of oxygen as in high altitude or with the use of gas mixtures such as nitrous oxide. with some of these situations it feel like you are breathing but you are in fact suffocating and causing damage to the brain.
