the bones of the skull form a rigid cranial compartment that contains:


Ans>>


brain tissue (80%)


CSF (10%)


blood volume (10%)




the pressure of _____ must remain _____ to maintain a normal _____


Ans>> brain tissues, CSF, and blood volume;




balanced;


intracranial pressure (ICP)


intracranial pressure (ICP)


Ans>> the pressure inside the skull, brain tissue, and CSF




1

,normal ICP for a resting, supine adult


Ans>> 5-15 mmHg




what causes change in ICP?


Ans>> volume changes in:




brain tissue


cerebral blood flow


CSF




what is the monroe-kellie hypothesis?


Ans>> an increase in the volume of one component must be compensated by a decrease in the

volume of another




EX: A slow-growing brain tumor increases the volume of brain tissue. What happens?


Ans>> The CSF production is slowed to compensate and maintain normal ICP.




2

, What happens once the volume of the brain tumor exceeds the volume of the CSF reduction?


Ans>> ICP increases




when the compensating mechanisms are totally exhausted....


Ans>> ICP will increase




ICP is maintained until _____


Ans>> a maximum point is reached




what is a major cause of increased ICP?


Ans>> cerebral edema




what are major causes of cerebral edema?


Ans>> trauma




hemorrhage
