RT Journal Article SR Electronic T1 CSF hydrodynamic studies in man. 2 . Normal hydrodynamic variables related to CSF pressure and flow. JF Journal of Neurology, Neurosurgery & Psychiatry JO J Neurol Neurosurg Psychiatry FD BMJ Publishing Group Ltd SP 345 OP 353 DO 10.1136/jnnp.41.4.345 VO 41 IS 4 A1 J Ekstedt YR 1978 UL http://jnnp.bmj.com/content/41/4/345.abstract AB With the patient in the supine position, the subarachnoidal space was infused with artificial CSF at several constant pressure levels. The resulting flow of liquid was recorded. By draining CSF at a low pressure the CSF production rate was determined. Normal values are given and discussed for (1) the resting pressure, (2) the conductance of the CSF outflow pathways, (3) the formation rate of CSF, (4) the pressure difference across the CSF outflow pathways, and (5) the sagittal sinus pressure. None of the variables showed any age dependence, nor was there any sex difference.
