3 main components that contribute to pressure within the skull

Brain tissue, CSF, blood flow

What is intracranial regulation?

the ability of the brain to compensate for changes in blood pressure, CSF, and brain tissue

Primary injury to brain

blunt trauma (car accident)

Secondary injury to brain

something else that causes injury to tissue (hypoxia, ischemia, edema)

what is normal ICP?

5-15 mmHg

How does the brain compensate for extra pressure?

shunts blood and CSF away from the brain

Normal CPP is?

60-100

CPP = _______ - ________

MAP - ICP

MAP should be greater than ____% in order to adequately perfuse organs

65

_____ ICP leads to ____ CPP

increased, decreased *the more pressure in the brain, the less the blood is able to reach the tissue because the vessels are being compressed
