Cardiopulmonary Bypass Equipment such as pump does the job of the heart, pumps blood through the body, and ensures that body tissues get the oxygen they need. More invasive life support, such as heart/lung bypass, is only maintained for a few hours or days, but patients with artificial hearts have survived for as long as 512 days.
