What triad of symptoms is associated with increased ICP and impending herniation?

The triad of symptoms associated with increased intracranial pressure (ICP) and impending herniation typically includes irregular breathing, hypertension, and bradycardia. This triad reflects the body's response to pressure on the brain.

Irregular breathing patterns often signify brainstem involvement as increased ICP compresses the brain structures, leading to alterations in respiratory control. Hypertension occurs as the body tries to maintain cerebral perfusion in the face of rising pressure. As the condition worsens, bradycardia is frequently observed, which is a reflex response due to increased intracranial pressure affecting the vagus nerve, leading to decreased heart rate.

Other symptom combinations listed do not represent the classic Cushing's triad, which is a significant indicator of elevated ICP and herniation risk. Understanding these symptoms is crucial for identifying patients who require immediate intervention to prevent severe neurological damage.
