What are the side effects of a heart lung machine?

The heart-lung machine, used during certain surgeries to temporarily take over the functions of the heart and lungs, can have several side effects. Common side effects include blood clot formation, bleeding, and potential damage to red blood cells. Patients may also experience inflammation, respiratory complications, or neurological effects due to reduced blood flow or air bubbles. Additionally, some may have a longer recovery time or experience cognitive changes post-surgery.
