Detection of Impaired Cerebral Autoregulation Using Selected Correlation Analysis: A Validation Study

Table 1

Characteristics of patients, receiving treatment for either SAH (subarachnoid hemorrhage) or TBI (traumatic brain injury) who were included in the study. The initial levels of consciousness at admission according to the Glasgow Coma Scale is depicted in column GCS; patients receiving decompressive craniectomy due to brain swelling are indicated by “y”; the next column describes the brain monitoring time for each patient in hours; outcome at last follow-up is noted in column GOS. The mean ICP and PRx columns describe the mean ICP and PRx values averaged over the entire observation time per patient.
