Objective To analyze the application effect of non-invasive bi-level positive airway pressure therapy in patients with acute respiratory distress syndrome (ARDS) . Methods A total of 50 patients with ARDS admitted to our hospital from February 2017 to January 2018 were randomly divided into control group and study group, with 25 cases in each group. The control group was treated with nasal continuous positive airway pressure (NCPAP) , and the study group was treated with bi-level positive airway pressure (BiPAP) . The two groups were compared with PaO2, PaCO2, and SpO2 for 48 hours before treatment. Time and treatment success rate. Results The PaO2, PaCO2 and SpO2indexes of the study group were better than those of the control group at 48 h, the difference was statistically significant (P＜0.05) . The oxygen treatment time of the study group was lower than that of the control group [ (70.35±14.33) h vs (88.79±12.63) h], and the success rate of treatment was higher than that of the control group (96.00％ vs 80.00％) , the difference was statistically significant (P＜0.05) . Conclusion Non-invasive bi-level positive airway pressure therapy for patients with ARDS can significantly improve the blood pressure index, shorten the oxygen therapy time and improve the treatment success rate.%目的 对急性呼吸窘迫综合征 (ARDS) 患者采取无创双水平气道正压通气治疗的应用效果进行分析.方法 选取2017年2月～2018年1月我院收治的50例ARDS患者, 随机分为对照组和研究组, 每组25例.对照组采取鼻塞式持续气道正压通气治疗 (NCPAP) , 研究组采取双水平气道正压通气治疗 (BiPAP) , 对比两组治疗前、治疗48 h的PaO2、PaCO2、SpO2指标、氧疗时间以及治疗成功率.结果 研究组患者经治疗48 h的PaO2、PaCO2、SpO2指标均优于对照组, 差异具有统计学意义 (P＜0.05) ;研究组氧疗时间少于对照组[ (70.35±14.33) h vs (88.79±12.63) h], 治疗成功率高于对照组 (96.00％vs 80.00％) , 差异具有统计学意义 (P＜0.05) .结论 采取无创双水平气道正压通气治疗ARDS患者, 可显著改善患者的气血分压指标, 缩短氧疗时间, 提高治疗成功率.
