Abstract
There is considerable evidence that CSF pressures at equilibrium are equal in magnitude to a pulse throughout the cerebrospinal fluid space (Marmarou et al. 1976). However, there is little data to show if transmission of CSF pressures are evenly distributed throughout the brain tissue. Moreover, if equilibrium is challenged by volume manipulation, it is not clear if the viscoelastic properties of brain are able to prevent uniform pressure gradients. Previous efforts to monitor rapid changes in brain tissue pressure using wick catheters were limited, due to poor frequency response. The purpose of this study was to determine to degree to which brain tissue pressure, as measured by a fiberoptic device (FOD), follows dynamic changes in CSF pressure induced by CSF volume manipulation.
