Mentions: The patient circulation and ECMO circuit were represented by a flow model (Fig. 1). Pump C was set at 3 1/min throughout. Pump E (ECMO) and S (shunt) were varied to provide 3 shunt fractions, (approximately 12, 25, 50%) at each of 3 ECMO flow rates (approximately 0.5, 1.0 and 2.0 l/min). Following a bolus injection of lithium chloride (0.15 mmol), its dilution curves were recorded simultaneously by sensors A and B (see Fig. 1). The flows through pump S and pump C were calculated from the 9 pairs of lithium dilution curves and compared to the actual flows delivered.
