Increased intracranial pressure (ICP) can significantly affect vital signs, and one of the hallmark responses to elevated ICP is bradycardia. When the pressure inside the skull rises, it can create a situation known as Cushing's triad, which includes hypertension, bradycardia, and irregular respirations. The pressure on the brain can stimulate the vagus nerve, leading to a decrease in heart rate, which is defined as bradycardia.

The relationship between increased ICP and bradycardia is primarily due to the body's attempt to regulate blood flow to the brain under pressure, as the heart rate slows in response to increased pressure, reflecting a compensatory mechanism. This vital sign change is crucial for EMTs and other healthcare professionals to recognize as it may indicate a life-threatening condition requiring immediate intervention. Understanding this physiological response is essential in emergency situations where ICP may be a concern, such as in traumatic brain injuries or strokes.
