The unconscious patient presents a challenging emergency in the intensive care unit. This is a dangerous time for the patient; patient evaluation and treatment must occur simultaneously. Clinical circumstances with immediate therapeutic consequences, such as hypoxia or hypoglycemia, must be identified and treated quickly.
