Quick Summary

Cardiopulmonary bypass is a medical procedure that temporarily replaces the function of a patient's heart and lungs during open-heart surgery. It involves using a heart-lung machine to oxygenate the blood and remove carbon dioxide, allowing surgeons to operate on a still, dry heart.123

The process involves diverting deoxygenated blood from the body into the heart-lung machine. There, it is oxygenated and then returned to the body's arterial system, ensuring vital organs receive oxygenated blood. This technology, first successfully used in the early 1950s, revolutionized heart surgery by enabling procedures that were previously impossible or extremely limited in duration. The use of a heart-lung machine is a key component of open-heart surgery, which addresses various cardiac conditions, including valvular disease, congenital heart defects, and coronary artery disease.134
