Understanding Mean Arterial Pressure Requirements

A nurse is caring for a patient who has undergone surgery for aortic aneurysm repair. Postoperatively, the patient is currently on a monitor that displays vital signs, including heart rate and blood pressure. The nurse understands that effective management of the patient's hemodynamics is essential for preventing complications. After reviewing the patient's arterial blood gas results, the nurse notes a mean arterial pressure (MAP) of 65 mmHg. To maintain adequate organ perfusion, the MAP should ideally be at least ___ mmHg.
