Information on the use of neuromonitoring in intensive care units is scattered but significant. Nurses who do not care for neurologically impaired patients on a daily basis may not have a strong understanding of the utility of various neuromonitoring techniques, why they are used, or how they are interpreted. Two main types of neuromonitoring that are frequently seen but poorly understood are reviewed here: transcranial Doppler sonography and electrophysiology. Information on these 2 techniques tends to be either superficial with limited applicability to the critical care setting or very technical. This review provides information about neuromonitoring to help guide critical care nurses providing care to neurologically impaired patients. (Critical Care Nurse. 2014;34[3]:30–40)
