Neuro ICU Flashcards
Rate of CSF per hour, per day, total CSF at any time
~20cc/hr
~500cc/day
Total CSF at any time about 125-150cc total
In the average adult human,
there is roughly 150 mL of CSF circulating
at any given moment. The ventricular
portion amounts to roughly 17% of the
total fluid volume, the rest of which lies
in the cisterns and subarachnoid space.
CSF forms at a rate of about 0.3–0.4 mL/
min; translating to 18-25 mL/hour and
430–530 mL/day
