Use of technology in the management of the severely brain-injured patient has increased over the past decade and can be confusing and overwhelming to the critical care nurse clinicians who are new to the field of neurology. This article will describe normal physiology and cerebral dynamics and potential abnormal physiology encountered after brain injury. The technology reviewed will include intracranial pressure monitoring, cerebral blood flow monitoring and autoregulation, cerebral oxygen consumption and tissue oxygen monitoring, metabolism, sedation, and temperature monitoring. Integration of appropriate technology into patient management will be discussed using a case study to explore the utility of information at the bedside. Recognizing the difficult task of trying to control secondary injury in our patients is the first step to better outcomes. Implementing the use of technology to mitigate the situation must be done with careful consideration and a team approach to achieve the greatest benefit for the patient.
