A heart-lung machine has a defect that causes it to stop pumping blood without sounding a warning alarm. In this case, what is likely to happen?

A heart-lung machine must keep blood circulating and oxygenated during a procedure. If it stops pumping without warning, the medical team may not realize immediately, and the patient could suffer life-threatening harm or die. Becoming uncomfortable or receiving the wrong treatment does not describe the most likely consequence of this failure.
