This study aimed to investigate the impact of chain management (defined as a systematic protocol integrating dynamic risk assessment, standardised nursing pathways, multidisciplinary coordination, and real-time biomarker monitoring to optimise clinical decision-making) on inflammatory markers (interleukin [IL]-1b, IL-6, IL-8, tumour necrosis factor[TNF]-a, and procalcitonin[PCT]), vascular endothelial function, blood gas parameters, and T lymphocyte subsets in patients with ARF. Methods: A retrospective analysis was conducted on 101 ARF patients admitted between October 2023 and December 2024. The patients were categorised into two groups: a conventional group (55 cases, receiving standard risk warning management) and a chain group (46 cases, undergoing chain management). Levels of inflammatory factors and vascular endothelial markers (nitric oxide[NO], endothelin-1 [ET-1], etc.) were measured using enzyme-linked immunosorbent assay (ELISA), blood gas function was evaluated with a blood gas analyser, and T lymphocyte subsets (CD3+, CD4+, and CD8+) were analysed via flow cytometry. Results: Compared to the conventional group, the chain group demonstrated significantly shorter durations of mechanical ventilation and ICU stays (P&amp;lt;0.05). Moreover, the chain group exhibited more pronounced reductions in inflammatory factors, including IL-1b, TNF-a, and PCT (P&amp;lt;0.05). Improvements in vascular endothelial function were also more evident in the chain group, with higher NO levels and lower ET-1 levels (P&amp;lt;0.05). Additionally, the chain group achieved better blood gas outcomes, characterised by higher PaO2 and lower PaCO2 levels (P&amp;lt;0.05), as well as greater increases in CD3+ and CD4+ cell counts (P&amp;lt;0.05). Conclusions: Chain management effectively mitigates inflammatory responses and enhances vascular immune function, endothelial function in ARF patients through multi-targeted interventions.<\/jats:p>","DOI":"10.5937\/jomb0-58099","type":"journal-article","created":{"date-parts":[[2025,5,12]],"date-time":"2025-05-12T03:20:47Z","timestamp":1747020047000},"page":"1405-1412","source":"Crossref","is-referenced-by-count":1,"title":["Chain management reduces inflammation (IL-1b, IL-6, IL-8, TNF-a, PCT) and improves vascular (NO, DD, VWF, and ET-1)\/immune function in acute respiratory failure: A retrospective cohort study"],"prefix":"10.5937","volume":"44","author":[{"given":"Yunxia","family":"Chen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xinyu","family":"Yuan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sisi","family":"Sun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenjuan","family":"Ding","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ningning","family":"Dai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"3964","reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Chen L, Rackley CR.
