Cushing's Reflex increases which parameter as a compensatory mechanism?

Explanation:
When intracranial pressure rises, the body attempts to preserve cerebral perfusion by increasing systemic arterial pressure. This raises mean arterial pressure, which helps maintain cerebral perfusion pressure (CPP = MAP − ICP) despite the high ICP. The heart rate typically falls due to a reflex (bradycardia), and respirations often become irregular, but the compensatory change is an increase in mean arterial pressure. Cardiac output is not the primary target of this reflex.
