With the development of technology, ECCO2R is not difficult to implement in intensive care unit. Many recently clinical studies have showed that ECCO2R can effectively remove CO2, reduce patient breathing work, improve the patient respiratory failure, and avoid endotracheal intubation. But there are also treated failure and high incidence of complications such as bleeding in the AECOPD patients with ECCO2R treatment, and the treatment related to airway management are less mentioned. Therefore, we set a more strict inclusion criteria in AECOPD patients and evaluate the clinical effectiveness and associated risk of ECCO2R in the treatment of AECOPD.
