Which triad of symptoms is associated with Cushing's Triad?

1. Low pulse, high respiratory rate, low BP

2. Raised systolic BP, lowered pulse, lowered respirations

3. Normal blood pressure, low heart rate, low respiratory rate

4. High pulse, low BP, high respiratory rate

The correct answer is: Raised systolic BP, lowered pulse, lowered respirations

Cushing's Triad is a clinical syndrome characterized by a specific triad of symptoms that indicates increased intracranial pressure (ICP) and possible brain herniation. The symptoms include hypertension (raised systolic blood pressure), bradycardia (lowered pulse), and irregular or abnormal respirations. The raised systolic blood pressure occurs as the body attempts to maintain cerebral perfusion despite the increasing pressure in the skull. Bradycardia is a compensatory response to the elevated blood pressure, and the respiratory changes reflect the effect of ICP on the brainstem, which can result in abnormal breathing patterns. This triad is an important clinical finding in emergency situations, particularly in trauma cases or instances of suspected intracranial hemorrhage. It serves as a critical indicator for healthcare providers to quickly identify and intervene in life-threatening conditions associated with brain injury. Recognizing Cushing's Triad promptly can lead to timely interventions aimed at relieving pressure and protecting brain function.
