This cross-sectional study aimed to evaluate the knowledge, attitudes, and practices (KAP) regarding oxygen therapy among emergency nurses in Sichuan Province, China. From November to December 2023, data were collected from 410 qualified emergency nurses (response rate: 63.08%) across 15 tertiary hospitals using a validated, self-developed questionnaire. Participants were predominantly female (83.9%), with mean scores of 16.74 ± 8.44 (range 0-26) for knowledge, 23.85 ± 1.73 (range 5-25) for attitude, and 55.29 ± 5.26 (range 12-60) for practice. Scores exceeding 70% in each domain were considered satisfactory. Notable knowledge gaps emerged regarding two critical aspects: 21.95% of respondents expressed uncertainty about oxygen administration in myocardial infarction patients with SpO > 93% without respiratory distress, while 14.88% demonstrated unclear understanding of Venturi mask applications for hypercapnic patients. Structural equation modeling (SEM) analysis demonstrated good model fit (CMIN/DF = 3.323, RMSEA = 0.075, IFI = 0.881, TLI = 0.870, CFI = 0.881). The results of the model revealed significant direct effects: knowledge positively influenced attitude (β = 0.184, p < 0.001), which in turn directly affected practice (β = 0.024, p < 0.001). The findings indicate that while Sichuan's emergency nurses maintain positive attitudes and proactive practices regarding oxygen therapy, significant knowledge deficiencies persist. These results emphasize the critical need for ongoing education and training programs to enhance nurses' knowledge and skills pertaining to oxygen therapy protocols, ultimately improving patient care outcomes.
这项横断面研究旨在评估中国四川省急诊护士对氧疗的知识、态度和实践（KAP）。2023年11月至12月，使用经过验证的自行编制问卷，从15家三级医院的410名合格急诊护士中收集数据（回复率：63.08%）。参与者以女性为主（83.9%），知识平均得分为16.74±8.44（范围0 - 26），态度平均得分为23.85±1.73（范围5 - 25），实践平均得分为55.29±5.26（范围12 - 60）。每个领域得分超过70%被认为是令人满意的。在两个关键方面出现了明显的知识差距：21.95%的受访者对SpO>93%且无呼吸窘迫的心肌梗死患者的氧疗表示不确定，而14.88%的受访者对高碳酸血症患者使用文丘里面罩的理解不清晰。结构方程模型（SEM）分析显示模型拟合良好（CMIN/DF = 3.323，RMSEA = 0.075，IFI = 0.881，TLI = 0.870，CFI = 0.881）。模型结果显示出显著的直接效应：知识对态度有正向影响（β = 0.184，p < 0.001），态度又直接影响实践（β = 0.024，p < 0.001）。研究结果表明，虽然四川的急诊护士对氧疗保持积极态度并积极实践，但仍存在明显的知识缺陷。这些结果强调了持续开展教育和培训项目的迫切需求，以提高护士在氧疗方案方面的知识和技能，最终改善患者护理结果。
