The aim of the study assesses static and dynamic cerebrovascular autoregulation daily over one week in patients with traumatic brain injury or intracranial hemorrhage to quantify the temporal profile of the autoregulatory status.

Condition Intervention

TBI (Traumatic Brain Injury)
Intracranial Hemorrhages
Other: There are no interventions in this study

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Serial Measurement of Static and Dynamic Cerebrovascular Autoregulation After Brain Injury
