To study the influencing factors of prognosis in elderly patients with chronic obstructive pulmonary disease (COPD) complicated with respiratory failure and the intervention effect of specialized nursing and respiratory training mode. A total of 168 COPD patients with respiratory failure admitted to our hospital from May 2021 to April 2023 were enrolled. According to their prognosis in the hospital, they were divided into good prognosis (121 cases) and poor prognosis (47 cases). logistic regression was used to analyze the independent risk factors of poor prognosis in elderly COPD patients with respiratory failure, and Pearson correlation coefficient was used to analyze the correlation.The results of multivariate analysis showed that arterial partial pressure of carbon dioxide (PaCO2), hypoxia-inducible factor-1α (HIF-1α), and High-sensitivity C-reactive protein (hs-CRP) to albumin (Alb) ratio (HCAR), Neutrophil count (Neut) to lymphocyte count (LYMPH) ratio (NLR) and Platelet count (PLT) to LYMPH ratio (PLR) were independent risk factors for poor prognosis in elderly COPD patients with respiratory failure (P < 0.05).Pearson correlation analysis showed that HIF-1α, HCAR and PLR were positively correlated with arterial blood gas index PaCO2 (P < 0.05), and NLR was not correlated with arterial blood gas index PaCO2 (P > 0.05).It can be seen that PaCO2, HIF-1α, HCAR, NLR and PLR are independent risk factors for poor prognosis in elderly COPD patients with respiratory failure, and special nursing and respiratory training mode intervention can be used to improve the prognosis of patients.
