Beyond the basics: interpreting altered mental status assessment findings

EMS providers frequently encounter patients who are not alert and present with an altered mental status, meaning their level of brain function is in question. Various physical examination techniques are employed during the assessment to determine the level of cerebral function and integrity of the brainstem. It is important to understand the limitations of these techniques, as well as potential findings that may cause you to erroreously interpret, re port and document the level of brain function. This information is often used to identify trends to determine if the patient's condition is deteriorating, remaining the same or improving.
