What happens to the brain after 20 minutes without oxygen?

Is dying from lack of oxygen painful?

What did it say begins to die without oxygen?
Brain cells begin to die within 3 to 5 minutes from lack of oxygen. The longer a person is without it the more severe the injuries will be. Once oxygen is restored, the body will begin to function again. However, there could be permanent damage that has already occurred.
