Abstract
Chronic obstructive pulmonary disease (COPD) is a significant global health issue that is characterized by airflow constriction and breathing difficulties. Non-invasive ventilation (NIV) is a recommended treatment for acute exacerbations of COPD (AECOPD), offering benefits over invasive mechanical ventilation (IMV). We aimed to evaluate the effectiveness, safety, and impact of NIV in managing AECOPD. The study adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed, Medline, Cochrane Library, Embase, and Google Scholar for relevant studies published between 2015 and 2024. Inclusion criteria focused on studies involving AECOPD patients treated with NIV, including randomized controlled, cohort, and observational studies. We included 10 studies that fit our inclusion criteria for a thorough review. From the studies selected, NIV demonstrated significant reductions in mortality rates, intubation rates, and hospital stays compared to IMV. Albeit the need to train healthcare providers is essential, high adherence to NIV guidelines was observed. Different NIV modes showed comparable efficacy, and structured weaning protocols reduced relapse rates. NIV is a highly effective and safe treatment for patients with AECOPD than IMV. High-flow nasal therapy (HFNT) is a viable alternative for patients intolerant to NIV. Further research should standardize treatment protocols and optimize NIV use in clinical practice.
