Eligible randomized controlled trials (RCTs) published from 2015 onward and evaluating nocturnal NIPPV in stable COPD were included. Primary outcomes were arterial blood gases (PaCO2, PaO2, pH); secondary outcomes included pulmonary function, 6-min walking distance (6MWD), and health-related quality of life (HRQoL). Pooled effects were calculated using fixed- or random-effects models. PROSPERO Registration (CRD42024608837).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Eight RCTs (736 patients) were analyzed. Nocturnal NIPPV significantly reduced PaCO2 and improved PaO2, with no significant change in pH. Regarding pulmonary function, FVC showed a non-significant trend toward improvement, and no significant differences were found for FEV1 or FEV1\/FVC. Notably, 6MWD showed significant improvement in the NIPPV group. For HRQoL, significant gains were observed in the Severe Respiratory Insufficiency (SRI) questionnaire, and COPD Assessment Test (CAT) scores were significantly reduced. No serious adverse events were reported.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Nocturnal NIPPV is a safe intervention for stable COPD, offering physiological and functional benefits by improving gas exchange and exercise capacity, while pulmonary-function effects were less consistent. However, its effects on spirometric airflow limitation and patient-reported outcomes should be interpreted cautiously because outcome instruments and the number of available studies differed. Further high-quality RCTs with standardized protocols are needed to define its optimal role in long-term management.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2026.1882152","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T05:37:27Z","timestamp":1784007447000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The safety and efficacy of nocturnal noninvasive positive pressure ventilation in patients with chronic obstructive pulmonary disease: a systematic review and meta-analysis"],"prefix":"10.3389","volume":"13","author":[{"given":"Ganying","family":"Huang","sequence":"first","affiliation":[{"name":"Department of Emergency, Affiliated Hangzhou First People\u2019s Hospital, School of Medicine, Westlake University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yitao","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Nursing, Zhejiang Chinese Medical University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yangbin","family":"Zhou","sequence":"additional","affiliation":[{"name":"Department of Emergency, Affiliated Hangzhou First People\u2019s Hospital, School of Medicine, Westlake University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huijie","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Emergency, Affiliated Hangzhou First People\u2019s Hospital, School of Medicine, Westlake University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinhong","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Emergency, Affiliated Hangzhou First People\u2019s Hospital, School of Medicine, Westlake University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weihong","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Emergency, Affiliated Hangzhou First People\u2019s Hospital, School of Medicine, Westlake University","place":["Hangzhou, Zhejiang, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"2300239","DOI":"10.1183\/13993003.00239-2023","article-title":"Global initiative for chronic obstructive lung disease 2023 report: GOLD executive summary","volume":"61","author":"Agust\u00ed","year":"2023","journal-title":"Eur Respir J"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.3390\/jcm11113180","article-title":"Hypercapnia in COPD: causes, consequences, and therapy","volume":"11","author":"Csoma","year":"2022","journal-title":"J Clin Med"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"Cd004104","DOI":"10.1002\/14651858.CD004104.pub4","article-title":"Non-invasive ventilation for the management of acute hypercapnic respiratory failure due to exacerbation of chronic obstructive pulmonary disease","volume":"2017","author":"Osadnik","year":"2017","journal-title":"Cochrane Database Syst Rev"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1469","DOI":"10.1016\/j.chest.2024.02.040","article-title":"Applying noninvasive ventilation in treatment of acute exacerbation of COPD using evidence-based Interprofessional clinical practice","volume":"165","author":"Farmer","year":"2024","journal-title":"Chest"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"1901003","DOI":"10.1183\/13993003.01003-2019","article-title":"European Respiratory Society guidelines on long-term home non-invasive ventilation for management of COPD","volume":"54","author":"Ergan","year":"2019","journal-title":"Eur Respir J"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"395","DOI":"10.1513\/AnnalsATS.202009-1171AG","article-title":"Summary for clinicians: clinical practice guideline for long-term noninvasive ventilation in chronic stable Hypercapnic chronic obstructive pulmonary disease","volume":"18","author":"Orr","year":"2021","journal-title":"Ann Am Thorac Soc"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"e74","DOI":"10.1164\/rccm.202006-2382ST","article-title":"Long-term noninvasive ventilation in chronic stable Hypercapnic chronic obstructive pulmonary disease.
