Quizplus · Accepted Answer

When blood flow to the brain is reduced by 40%, cerebral tissue becomes acidotic. When the blood flow to the brain is reduced by 60% the electroencephalogram (EEG) pattern changes and the client is at risk for significant brain tissue damage. Cerebral metabolism is altered, which eventually leads to brain tissue hypoxia and areas of brain tissue ischemia.
