    Heart-Lung Machine
    A heart-lung machine adds oxygen to blood from your heart and pumps it back into your body. It is used to take over the function of your heart and lungs during “on-pump” surgical procedures such as conventional coronary artery bypass. Watch this animation to see how it works.

  • A heart-lung bypass machine is used during open heart surgery to allow blood to temporarily bypass the heart. The machine enriches the blood with oxygen and pumps it through your body so surgeons can work on a stopped heart.
