Question Answer
What are the general compensatory measures in someone with increased ICP?
Show Answer
Decrease in cerebral blood volume; decrease in cerebral spinal fluid (easiest); tissue expansion.
What is the normal ICP level?
Show Answer
5-15; measured by a lumbar puncture or catheters.
What is the hypothesis for ICP called?
Show Answer
Monro-Kellie Closed Box Hypothesis
If CPP is greater than _______, this is called hyperfusion and can lead to ICP.
Show Answer
100 mmHg
The Glasgow coma scale is used to track progress in _______ conditions.
Show Answer
acute (*not used for chronic conditions like strokes)
In the Glasgow coma scale, the _______ the number, the better the prognosis.
Show Answer
higher
What is used to measure level of consciousness?

What are the stages of ICP?
Show Answer
Stage 1: intracranial hypertension, vasoconstriction and external compression of the venous system. Stage 2: increased pressure causes ischemic neurons which leads to systemic arterial compression/ vasoconstriction. Stage 3: brain tissue hypoxia and hypercapnea
What is the cycle of increased ICP?
Show Answer
Increased ICP; decrease in CSF, then CBF (vasoconstriction to decrease BV); tissue expansion; hypoxia; increase PCO2 (hypercapnea) and decrease pH (acidosis); vasodilation, edema and increase ICP.
Where do sensory fibers decussate?
Show Answer
In the medulla or spinal column.
Where do motor fibers decussate?
Show Answer
