This learning activity provides a comprehensive overview of intracranial pressure (ICP) monitoring in neurocritical care. It covers the fundamentals of ICP, including normal values and the Monro-Kellie doctrine, and explores various factors affecting ICP. The learning activity discusses indications for ICP monitoring, detailing both invasive and non-invasive monitoring methods. It then delves into the interpretation of ICP readings, including waveform analysis and derived indices. The management of elevated ICP is addressed, covering general measures, first-tier therapies, and second-tier interventions. The learning activity also highlights important nursing considerations in ICP monitoring and management, potential complications, and emerging technologies in the field. Overall, it serves as a thorough resource for understanding the crucial role of ICP monitoring in managing severe neurological conditions.
