ICP || Guaranteed Pass.
ICP (intracranial pressure) correct answers -*pressure* exerted on the brain by *brain tissue,
blood, and CSF*
-if any of these *increase* then the other two elements must *decrease*
intracranial compliance correct answers -ability of the body to compensate by adjusting levels of
components
-good compliance = ICP is good
-decreased compliance = ICP increases
CPP (cerebral perfusion pressure) correct answers -measures *cerebral blood flow*
-amount of pressure required to perfuse the brain
*Decreases*
-Why?: increased ICP means that there is too much pressure in the brain so blood in the brain
decreases to compensate correct answers When ICP increases, what happens to CPP?
*MAP-ICP=CPP*
CPP decreases with:
-decreased MAP
-increased ICP correct answers What is the formula for CPP? What changes in the formula would
decrease CPP?
60 mmHg or greater correct answers What is the normal value for CPP?
0-15 mmHg correct answers What is the normal value for ICP?
must be *15 or greater* for *5 min or more* correct answers What is the time frame for ICP to
be considered increased?
, -intraventricular catheter
-intraparenchymal sensor/probe
-subarachnoid bolt correct answers What are the three ICP monitoring devices?
inserted at bedside or in OR correct answers Where can ICP monitoring devices be inserted?
intraventricular catheter correct answers -*most common & gold standard* for ICP monitoring
-placed in the *ventricles (innermost part of the brain)*
*Advantages*
-ability to monitor pressure & drain CSF
*Disadvantages*
-increased risk of infection
intraparenchymal sensor/probe correct answers -placed in the parenchyma of the brain
*Advantages*
-accurate measurement of ICP
*Disadvantages*
-inability to drain CSF
subarachnoid bolt correct answers -bolt or screw placed into the subarachnoid area
*Advantages*
