Fig. 3

Extracorporeal elimination of carbon dioxide (CO₂) depending on blood flow and sweep gas flow with a membrane lung surface of 0.4m² (a) and 0.8m² (b). The extracorporeal CO₂ elimination was plotted against sweep gas flow. Blood flow was titrated from 300 to 900 mL/min (a) and 300 to 1800 mL/min (b). Each data point represents the mean and standard deviation among nine pigs. Of note, compared to Fig. 1, the values shown are the absolute and non-normalized CO₂ values, demonstrating the physiological variance of the CO₂ amount before the membrane lung in an animal ECCO₂R experiment
