- Cardiopulmonary bypass
- Bypass of the heart and lungs as, for example, in open heart surgery. Blood returning to the heart is diverted through a heart-lung machine (a pump-oxygenator) before returning it to the arterial circulation. The machine does the work both of the heart (pump blood) and the lungs (supply oxygen to red blood cells).
* * *a method by which the circulation to the body is maintained while the heart is deliberately stopped during heart surgery. The function of the heart and lungs is carried out by a pump-oxygenator (see heart-lung machine) until the natural circulation is restored.
* * *diversion of the flow of blood to the heart directly to the aorta, via a pump-oxygenator, avoiding both the heart and the lungs; a form of extracorporeal circulation used in heart surgery.
