Influence of Intracranial Components on Epidural Pulse Pressure

It is well known that the pulse pressure (PP) of the intracranial pressure pulse wave increases with rising intracranial pressure (ICP). However, the PP at the same ICP value is not always identical in various intracranial pathologies. The present study was performed to clarify the changes of PP with alterations in intracranial components (water content of brain tissue, blood and cerebrospinal fluid).
