Intracranial Pressure Pulse Wave Form and Its dp/dt Analysis of Plateau Waves
It is generally accepted that plateau waves reflect vasodilatation with a subsequent increase in cerebral blood volume (CBV) (Lundberg et al. 1968). It has also been shown that the ICP-pulse wave form changes with intracranial compliance and vasotonicity (Avezaat et al. 1986). The configuration of the ICP-pulse wave represents three fairly consistent components (P1, P2 and P3) (Cardoso et al. 1983). The present study was performed to investigate how each component of the ICP-pulse wave changed during the up- and downward course of plateau waves.
