PATHOPHYSIOLOGY
Brain suffers from traumatic injury
Brain sweeling or bleeding Increasing the intracranial pressure
Rigid cranium allows no room for expansion Of contents so intracranial pressure increases
Pressure on blood vessels within the brain Causes blood flow to the brain slow
Cerebral hypoxia and ischemia occur
Intracranial pressure continues To rise, brain may herniate
Cerebral blood flow ceases
Brain death
