The effect of whole body position on lumbar cerebrospinal fluid opening pressure

The effect of whole body position on lumbar cerebrospinal fluid opening pressure

<p>Abstract</p> <p>We compared cerebrospinal fluid (CSF) opening pressure measurements in the lumbar subarachnoid space between the flexed position (F-OP) and relaxed position (R-OP) in recumbent patients. We devised an equation for using F-OP to determine the existence of raised i...
