Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1]

Cardiopulmonary bypass is a procedure that diverts blood circulation away from your heart and lungs. It’s a routine part of many heart surgeries. “Cardio” refers to your heart, and “pulmonary” refers to your lungs. “Bypass” means to avoid something by going around it.

2024年8月12日 · Cardiopulmonary bypass (CPB) is a critical technology in cardiac surgery, allowing for the temporary replacement of the heart and lung functions during intricate surgical procedures. The CPB circuit, or heart-lung machine, diverts venous blood from the patient, oxygenates and filters it, and then returns it to the arterial system, ensuring ...

Cardiopulmonary bypass (CPB) provides a bloodless field for cardiac surgery. It incorporates an extracorporeal circuit to provide physiological support in which venous blood is drained to a reservoir, oxygenated and sent back to the body using a ...

2023年12月5日 · Cardiopulmonary bypass (CPB) is a form of extracorporeal circulation in which the patient's blood is diverted from the heart and lungs and rerouted outside of the body. The normal physiologic functions of the heart and lungs, including circulation of blood, oxygenation, and ventilation, are temporarily taken over by the CPB machine.

2020年11月3日 · Cardiopulmonary bypass (CPB) replaces the function of the heart and lungs while the heart is arrested to provide a bloodless, stable surgical field

2022年2月6日 · The role of cardiopulmonary bypass (CPB) is to take over the function of the heart and lungs, and to deliver oxygen uninterrupted to the vital end organs for the purposes of heart-lung surgery.

2017年12月13日 · This post outlines the steps in traditional, central cannulation for cardiopulmonary bypass (CPB). Depending on the nature of the surgery and the patient’s comorbidities, other sites are often cannulated (left heart bypass, femoral-femoral peripheral cannulation, etc.)

2024年8月12日 · Since its inception in the mid-twentieth century, CPB has enabled complex heart surgeries, including coronary artery bypass grafting, valve replacements, and congenital heart defect corrections. Continuous advancements in CPB technology have enhanced safety, reduced complications, and improved patient outcomes.

2024年1月25日 · The core functions of CPB establish mechanisms to (1) drain the body’s deoxygenated blood, (2) oxygenate, heat, and pump extracorporeal blood, (3) re-introduce oxygenated blood to the body, and (4) establish cardioplegia while providing the heart with oxygenated blood (Fig. 9.1).
