The role of non-invasive ventilation used immediately after planned extubation for adults with chronic respiratory disorders

Abstract Objectives: To estimate the benefits of non-invasive ventilation (NIV) used immediately after planned postextubation in patients with chronic respiratory disorders. Methods: Cochrane Library, PubMed, the Chinese BioMedical Literature Database of clinical trials (CBD) and Embase were searched for pertinent studies by 2 trained investigators.
