Slow vasogenic fluctuations of intracranial pressure and cerebral near infrared spectroscopy—an observational study

Background/purpose Increased slow-wave activity in intracranial pressure (ICP) signifies an exhausted cerebrospinal compensatory reserve across a range of conditions. In this study, we attempted to describe synchronisation between slow waves of ICP and of near-infrared spectroscopy (NIRS) variables during controlled elevation of ICP.
