Intracranial pressure (ICP) is an important "cranial vital sign" to track a variety of conditions affecting the brain and cerebrovascular space. ICP measurement, however, requires surgical penetration of the skull and placement of a pressure-sensitive probe in the brain parenchyma, or insertion of a catheter into the ventricular or extra-ventricular cerebrospinal fluid spaces. This invasiveness and the associated risks cause ICP measurements in current clinical practice to only be made in a small subset of patients whose diagnosis and treatment could benefit from knowing ICP. The overall goal of this study is to assess the feasibility of a noninvasive approach in 210 patients to patient-specific determination and monitoring of ICP in a variety of conditions in which invasive ICP monitoring is currently clinically mandated.
