This educational video explores the examination of a comatose patient. It details the methods to assess a patient’s depth of coma using the Glasgow Coma Scale, evaluates brain stem function, and checks for focal signs. Techniques such as monitoring pupillary responses, corneal reflexes, and assessing respiratory patterns are demonstrated to differentiate coma from other states like vegetative state and locked-in syndrome. The video emphasizes the importance of accurate diagnosis and understanding the physiological findings and prognoses of conditions mimicking coma.
