What is the purpose of the roller pump during ECMO?

Explanation:
The roller pump’s job in ECMO is to drive blood through the circuit, creating and maintaining the flow that moves blood from the patient, through the oxygenator, and back to the patient. This artificial circulation supports systemic perfusion and effectively augments cardiac output when the heart isn’t able to pump adequately. Rewarming is accomplished by the heat exchanger, not the pump. Bubble removal and gas exchange are handled by the bubble traps and the oxygenator, respectively; the pump’s role is simply to circulate the blood.
