Ultra-Protective Lung Ventilation With Extracorporeal CO2 Removal for Moderate ARDS

HLS5.0 Cardiohelp® (Getinge Cardiopulmonary Care, Rastatt, Germany): 1.3 m² polymethylpentene hollow fiber membrane oxygenator. The extracorporeal blood flow is in the range of 1000 to 1500 mL/min. Sweep gas (air or oxygen) is drawn through the hollow fibers by a vacuum pump, creating a diffusion gradient for gas exchange across the membrane.
