Neonatal in vitro ECMO model. A graphical depiction of a test circuit adapted from a previous study, which includes each of the in vitro circuit components that include the reservoir bag, pump, and oxygenator. Blood is drained from the reservoir bag, into the pump, pushed through the oxygenator, across an arterial catheter, and returns to the reservoir bag. To simulate the arterial resistance of an actual patient, an arterial catheter connected the oxygenator to the blood reservoir.
