This course gives nurse anesthesiologists a practical roadmap for using non-invasive ICP tools to protect the brain when invasive monitoring isn’t possible or ideal. You’ll review the core physiology of ICP and CPP, then dive into how to apply technologies like TCD, ONSD ultrasound, NIRS, and other emerging methods in real perioperative and ICU scenarios. Clear, clinically focused sections walk you through recognizing worrisome ICP trends, adjusting ventilation, hemodynamics, and anesthetic depth in response, and integrating “good enough” non-invasive data into high-stakes decisions to prevent secondary brain injury.
