Fig. 2.

In vitro CO₂ removal rates. The dual axes show experimental results, as well as the expected values when the system is scaled up by a factor of 22.5. The expected scaled up values are in gray, while the actual values are in black. Triangle symbols: Q _b = 11 mL/min (248 mL/min scaled up), pCO_{2, inlet} = 100 mmHg; diamond symbols: Q _b = 18.7 mL/min (421 mL/min scaled up), pCO_{2, inlet} = 50 mmHg; square symbols: Q _b = 11 mL/min (248 mL/min scaled up), pCO_{2, inlet} = 50 mmHg. Single asterisk indicates p < 0.05 between different blood flow rates (diamond and square symbols). Double asterisks indicate p < 0.05 between different inlet pCO₂ values (triangle and square symbols)
