"The Heart-Lung Machine" (textbook)

The heart-lung machine is a medical device used during certain surgeries, particularly heart surgeries. It takes over the functions of the heart and lungs, allowing the surgeon to operate on a still heart. The machine does this by pumping blood through a system that oxygenates it and removes carbon dioxide, just like healthy lungs. By maintaining blood circulation and oxygen levels, it ensures the body's organs receive the necessary blood supply while the heart can be safely repaired or replaced, ultimately enhancing patient outcomes during complex procedures.
