From: Blood flow but not cannula positioning influences the efficacy of Veno-Venous ECMO therapy
Recirculation charts for the two different ECMO flows. Oxygen recirculation for different cannula positions and the two considered ECMO flows. (a) 3 L/min. Mean: 7.66, standard deviation: 2.29. (b) \(5\,\hbox {L}/\hbox {min}\). Mean: 33.57, standard deviation: 2.82. In the 3 L/min case a clear pattern emerges: when the cannulae are closer to each other, more recirculation occurs. In the \(5\,\hbox {L}/\hbox {min}\), on the other hand, the blood comes in so fast that its behaviour is unaffected by the small changes in the cannulae’s positions. Regardless, recirculation is much more intense in the \(5\,\hbox {L}/\hbox {min}\) case.
