Have you ever wondered what happens when a person's heart or lungs become so sick that even the most advanced ventilators, medications, and intensive care treatments are no longer enough? Is there a way to keep someone alive while giving their body a chance to heal? The answer may lie in a remarkable technology called ECMO. Often described as one of the most advanced forms of life support available today, ECMO has helped save the lives of patients who, only a few decades ago, might not have survived. Yet despite its growing use, many people have never heard of it—or misunderstand what it actually does.
