From: Blood flow but not cannula positioning influences the efficacy of Veno-Venous ECMO therapy
Saturation charts for the two different ECMO flows. Saturation levels at the Tricuspid valve for different cannula positions and the two considered ECMO flows. (a) 3 L/min. Mean: 83.12, standard deviation: 0.49. (b) \(5\,\hbox {L}/\hbox {min}\). Mean: 92.21, standard deviation: 0.37. In both charts, the values span a small range, meaning that moving the cannulae influences the ECMO efficacy by less than \({2}\,\%\), hardly compensating the risk of generating an infection. On the other hand, the worst \(5\,\hbox {L}/\hbox {min}\) configuration performs much better than the best 3 L/min one, indicating that increasing the ECMO flow offers the most benefit.
