The field of neurocritical care and traumatic brain injury management is rapidly evolving. We are shifting from older (but not entirely outdated) monitoring techniques to novel diagnostic and therapeutic advances in critical care medicine. Managing intracranial pressure crises involves the careful tiptoeing of a line between maintaining brain circulation and yet reducing intracranial fluid volume. And many of our interventions rely on one simple mathematical construct:

CPP = MAP - ICP

[Cerebral perfusion pressure = Mean arterial pressure – Intracranial pressure]

The importance of this formula cannot be understated. So we are spending 35 minutes today reviewing it, and discussing pearls and pitfalls of ICP monitoring and management. But believe me, it’s worth it.

Produced by James E. Siegler and Jon Rosenberg. Music courtesy of Unheard Music Concepts, Rafael Archangel, Milton Arias, and Quincas Moreira. The opening theme was composed by Jimothy Dalton. Sound effects by Mike Koenig and Daniel Simion. Unless otherwise mentioned in the podcast, no competing financial interests exist in the content of this episode.
