| 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 |
