Abstract

The importance of ICP monitoring has recently increased in patients with severe neurological disorders caused by increased ICP. Clinical use of these data is vital. One of the major aims of monitoring ICP is to provide an “early warning sign” of dangerous intracranial hypertension and subsequently to prevent worsening intracranial conditions. ICP monitoring provides us with information about not only the absolute value of ICP but also the ICP pulsewave, because the configuration and amplitude of CSF pulsations are to a certain extent an index of intracranial compliance. Since 1979, we have analysed the CSF pulse waveform clinically and experimentally under various conditions (Nitta et al. 1982) and have realized that the CSF pulse waveform is an important early indicator of change in the intracranial situation. The present study was designedto clarify how the arterial pulsewave transmits through the intracranial cavity and produces the CSF pulsewave.
