Which option lists the components of Cushing's Triad?

• A. Increased BP, Decreased HR, Irregular respirations
• B. Increased BP, Increased HR, Irregular respirations
• C. Decreased BP, Decreased HR, Regular respirations
• D. Increased BP, Decreased HR, Regular respirations

Answer: (A)

Cushing's Triad signals rising intracranial pressure and reflects a brainstem-mediated response. The classic components are increased systolic blood pressure (a widened pulse pressure), a slower heart rate (bradycardia), and irregular or altered respirations. This combination happens because the brain attempts to maintain cerebral perfusion as intracranial pressure climbs: the sympathetic system raises blood pressure to push blood into the brain, the brainstem reflexes slow the heart, and the affected respiratory centers produce irregular breathing patterns. So the option that lists increased blood pressure, decreased heart rate, and irregular respirations matches these signs perfectly. These changes are a late and concerning sign, often indicating potential brain herniation, and require immediate stabilization and rapid transport.
