Patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) often suffer from respiratory failure and require respiratory support therapy. High-flow nasal cannula oxygen therapy (HFNC) and non-invasive positive pressure ventilation (NIPPV) are commonly used non-invasive respiratory support methods. HFNC can provide precisely heated and humidified high-flow oxygen, reducing dead space and increasing alveolar ventilation. NIPPV can supply stable high-concentration oxygen and improve gas exchange. This article reviews the application of HFNC and NIPPV in the acute exacerbation stage of COPD, aiming to provide references for reasonable clinical selection.
