What is Cushing's triad characterized by?

Cushing's triad is a specific clinical syndrome associated with increased intracranial pressure (ICP) and is characterized by three classical signs: irregular breathing (which can also include periods of apnea), increased mean arterial pressure, and bradycardia. The irregular breathing reflects disturbances in the brain's regulation of respiratory patterns, which can occur when there is pressure on the brainstem. The increase in mean arterial pressure is a compensatory response to maintain cerebral perfusion in the setting of elevated ICP, while bradycardia occurs as a response to increased pressure on the brain, leading to a reduced heart rate.

This triad serves as a critical indicator for healthcare providers, signaling the need for immediate assessment and intervention in suspected cases of significant intracranial pressure, such as after head trauma or in conditions leading to brain swelling. Understanding Cushing's triad is essential in pediatric advanced life support, as it aids in the timely recognition of potentially life-threatening neurological conditions.
