Cushing's Reflex is a physiological response that occurs when there is increased pressure in the skull, often due to conditions like a brain injury or tumor. This reflex is characterized by a specific pattern of changes in heart rate and blood pressure, where the body attempts to maintain blood flow to the brain despite rising intracranial pressure. The reflex typically involves an increase in blood pressure and a decrease in heart rate, known as bradycardia. This response is a protective mechanism, signaling that the body is trying to ensure adequate oxygen and nutrient delivery to the brain during times of stress or injury.
