In cases of brain herniation, the body's typical initial compensatory response involves increasing blood pressure. This physiological reaction occurs as a way to maintain cerebral perfusion pressure despite the increased intracranial pressure. When the brain is under pressure, it can lead to reduced blood flow and oxygen delivery to brain tissues, which the body attempts to counteract by elevating blood pressure. This response is part of a broader mechanism known as the Cushing reflex, where the body works to ensure that the brain continues to receive adequate blood flow even in compromised situations.

The increase in blood pressure serves to push blood into the cranial cavity and maintain adequate circulation to vital brain structures, thereby attempting to preserve function in the face of potentially life-threatening conditions like brain herniation. Understanding this initial response is critical in managing patients with neurological emergencies effectively.
