Abstract
An artificial lung system for a patient having a membrane lung system having an gas inlet, a blood inlet, a blood outlet, and an exhaust; a gas system operably coupled to the gas inlet of the membrane lung system; a gas phase CO2 sensor disposed downstream of the exhaust of the membrane lung system and monitoring an exhaust gas CO2 (EGCO2) level and/or an blood oxygen saturation sensor disposed upstream of the blood inlet of the membrane lung system and monitoring a blood oxygen saturation level; and a feedback controller receiving the CO2 signal and/or blood oxygen saturation signal and outputting a control signal to control gas flow and/or blood flow.
