Heart surgery: The machine is connected via catheters to an inlet from the venous system and an outflow in the aorta, the unoxygenated blood flows into the machine and gets oxygenated and then pumped out once oxygenated to the aorta to supply the body. These are surgical connections. When the operation is done, they are removed and the heart is restarted.

Cardiopulmonary : Cardiopulmonary bypass machine supports the patient. Tubes- cannulae are placed in the veins to drain by gravity the blood to an oxygenator receptacle, the blood is oxygenated, and pumped through another cannula system to the arterial circulation., the are multiple kinds, and sizes of these tubes! we can place them in any big artery or vein to get the flow we need.

A 41-year-old member asked:

During an open heart surgery, does the heart stop before they put the heart lung machine or they put it while the heart is beating?

After: The heart lung machine takes over the function of the heart and lungs so that it becomes safe to make the heart stop after the person is put on the heart lung machine. (so, a patient is first put on the heart lung machine while the heart is still beating>).
