Cushing triad reflects a dangerous rise in intracranial pressure with brainstem involvement. The body responds to impaired cerebral perfusion by increasing systolic blood pressure to maintain blood flow, which broadens the pulse pressure. At the same time, the surge in ICP triggers a reflex bradycardia. Brainstem compression then disrupts respiratory control, producing irregular breathing patterns. So the combination of widened pulse pressure, bradycardia, and irregular respirations fits this triad. Tachycardia or regular respirations would not align with this scenario, and a narrow pulse pressure would not indicate the hypertensive state seen with elevated ICP.
