Abstract: Objective: To apply the best evidence for pulmonary rehabilitation training for patients receiving high -flow nasal cannula oxygen therapy in health service and evaluate the effectiveness. Methods: An evidence-based team was formed guided by the i-PARIHS framework, and the evidence was converted and applied according to five steps including evidence acquisition, baseline review, obstacle analysis, evidence application, and effect evaluation. Using cluster sampling method, 45 nurses and 120 patients with chronic respiratory diseases who applied HFNC were included. Thepromotion and obstacle factors of the review indicators with a clinical implementation rate of<90% were evaluated and action strategies were developed. Clinical standard implementation rate of nurses and the 6-minute walking distance of patients before and after implementing interventions based on comparative evidence were compared. Results: Thirteen best evidences were included finally and 14 review indicators were developed. The implementation rate of the review indicators to improve the best evidence-based practice of pulmonary rehabilitation training was more than 90%, and the implementation rate of 14 indicators was improved after intervention. In addition, the 6-min walking distance of patients in the evidence application stage was better than that in the baseline review stage (P<0.05). Conclusion: Through the evidence -based practice of pulmonary rehabilitation based on i-PARIHS framework, the effect of pulmonary rehabilitation training on HFNC patients was effectively improved and the activity endurance of patients was enhanced.
