In 1930 the young American surgeon, John H Gibbon, saw a patient die during a heart operation. He then dreamt about inventing a machine that could replace the heart during heart surgery. In 1953 – 23 years later – he performed the first successful operation with the aid of a heart-lung machine.

The heart-lung machine takes the place of the heart and lungs. It consists of a pump and an oxygenator – an artificial lung. The machine is connected to a circulatory system. It ensures that the blood receives oxygen and removes carbon dioxide before the blood is pumped back into the body. The heart must be completely still to undergo surgery, therefore cold blood mixed with potassium is added via the heart-lung machine during surgery.
