Objective:
Cerebrovascular reactivity can provide a continuously updated individualized target for management of cerebral perfusion pressure, termed optimal cerebral perfusion pressure. The objective of this project was to find a way of improving the optimal cerebral perfusion pressure methodology by introducing a new visualization method.
Data Sources:
Four severe traumatic brain injury patients with intracranial pressure monitoring.
Data Extraction:
Data were collected and pre-processed using ICM+ software.
Data Synthesis:
Sequential optimal cerebral perfusion pressure curves were used to create a color-coded maps of autoregulation - cerebral perfusion pressure relationship evolution over time.
Conclusions:
The visualization method addresses some of the main drawbacks of the original methodology and might bring the potential for its clinical application closer.
