Abstract:

To summarize the nursing experience of 3 patients with severe hypercapnia during the acute exacerbation of chronic obstructive pulmonary disease（COPD） undergoing extracorporeal carbon dioxide removal（ECCO₂R），as well as adjustment of oxygen therapy support strategy and implementation of non-pharmacological airway clearance techniques. Additionally，the nursing focus includes all process nursing of ECCO₂R，which covers the key aspects such as catheter selection and placement management，pre-flush setting and bubble handling，dual connection with initial parameter setting for patients，heparin pathway management and bleeding monitoring，observation of thrombosis formation and pressure monitoring during operation and self-examination，evaluation of carbon dioxide removal efficiency and implementation of decommissioning tests. After careful treatment and nursing，2 patients recovered and were discharged，and a patient’s condition improved and was transferred to the respiratory ward for further treatment，and was discharged after 5 days.
