A member asked:

How many minutes without oxygen does it take before a child suffers permanent brain damage?

A doctor has provided 1 answer

Varies: Depends on whether the deprivation is complete or not. The brain uses 20% of oxygen with every breatn taken because it is the most metabolically tissue in the body.Complete deprivation will kill the lower part of the brain in seconds.
