A closed head injury may present with signs known as Cushing's triad. All of the following are part of Cushing's triad EXCEPT:

Explanation:
Cushing's triad signals rising intracranial pressure with brainstem involvement. The hallmark signs are a rise in systolic blood pressure with a widened pulse pressure, a slowing of the heart rate (bradycardia), and irregular respirations (often patternless or with periods of apnea). An increasing respiratory rate is not part of the triad; respirations tend to be irregular or decreased due to brainstem dysfunction. Recognizing this pattern is crucial because it points to dangerous ICP and potential herniation, requiring urgent management.
