I get conflicting info from textbooks and internet.

Some say 5-10

Some say 50-200

this is from Lab Values (Cerebrospinal Fluid Analysis) in Lewis, Heitkemper, and Dirksen Medical-Surgical Nursing in Canada:

Test - Normal Values/SI Units (Conventional Units)

Pressure - 60 - 150 mm H2O (same as SI units)

Could it be the difference between the pressure measured as ICP and lumbar puncture pressure?

60-150 - lumbar CSF pressure

0-10 - ICP (CSF)

well look at what i think...

i far as i knw...

CSF pressure may be measured using a vrtical tube atttached to a lumbar puncture needl. IT REMAINS FAIRLY CONSTANT ABOUT 10 cm H2O when a person is lying on his side and about 30cm H2O whrn sittin up...

hey so let me knw ..i am also a bit confused now....

It is going to differ significantly as to where it is being measured. ICP is CSF that is in the cranium, and it is much more restricted as to how high that it can get without causing swelling and seizures, and everything else that goes along with high ICPs.

There are several threads that address this topic on the Neurosurgical Forum, have a look there.
