What is a characteristic symptom of Cushing's triad?

Cushing's triad is a clinical syndrome characterized primarily by three key signs that indicate increased intracranial pressure (ICP). One of the hallmark features of this triad is increased blood pressure, which occurs as a compensatory mechanism in response to the rising ICP. The body attempts to maintain cerebral perfusion, leading to elevated systolic blood pressure.

This increase in blood pressure may often be accompanied by a decrease in pulse rate (bradycardia) and irregular respirations. This triad of findings is critical in emergency and critical care settings, as it signals potential life-threatening conditions such as traumatic brain injury or brain herniation that require immediate medical intervention. Understanding these symptoms is vital for paramedics and healthcare professionals managing patients with suspected intracranial hypertension.
