CPB
Also written as: CPB — Cardiopulmonary Bypass
Cardiopulmonary bypass; mechanical circulation and oxygenation during cardiac surgery.
Full Definition
Cardiopulmonary bypass is a technique that temporarily takes over the function of the heart and lungs during cardiac surgery. Blood is diverted from the heart to a machine that oxygenates and pumps it back to the body, allowing surgeons to operate on a still, bloodless heart. CPB management requires close collaboration between the anesthesiologist and perfusionist to maintain adequate organ perfusion and hemostasis.
