From: A mock circulation loop to test extracorporeal CO2 elimination setups
Schematic layout of the mock. The mock consists of two interconnected circuits with one membrane lung (ML) each. The primary circuit represents the simulated organism. It has a blood flow of 5 L/min and creates a hypoxic and hypercapnic (venous) environment with N2 and CO2 as sweep gases. The actual ECCO2R setup to be evaluated is built into the test circuit. CO2 removal over the ML in the test setup is quantified. In this work, the influence of different hemoglobin concentrations (12, 7, and 4 g/dL), different sweep gases (O2 vs. air), and low-flow scenarios (blood flow amplification with recirculation channel, acidification of recirculated blood) on CO2 removal are simulated
