Cardiovascular Perfusionists are primarily responsible for operating the heart-lung machine and related equipment during cardiac surgery, ensuring proper blood circulation and respiratory support while the heart is stopped. They work closely with surgeons, anesthesiologists, and operating room staff to monitor vital signs and adjust equipment as needed. In addition, perfusionists may assist in procedures involving ventricular assist devices, ECMO, or organ transplants. Their daily tasks also include preparing equipment, documenting perfusion activities, and participating in ongoing training and team briefings to maintain high standards of patient care.
