目的 探讨和分析无创呼吸机在呼吸衰竭急诊患者中的应用效果。方法 本次研究选取我院在2011年1月-2016年1月 期间收治的40例呼吸衰竭急诊患者，按照就诊顺序将其分成两组，一组是采用常规急救方法治疗的对照组，一组是 采用无创呼吸机治疗的观察组，每组20例，观察两组患者的救治成功率、临床症状改善情况。结果 观察组患者救 治成功率较高，为95%，与对照组70%救治成功率比较，差异具有统计学意义(P<0.05)；治疗前后,观察组患者临床 改善情况较好，与对照组患者比较，差异具有统计学意义(P<0.05)。结论 呼吸衰竭急诊患者采用无创呼吸机进行 救治，成功率高，临床症状改善效果好，具有推广价值，值得推广。

Objective To investigate and analyze the effect of noninvasive ventilator in emergency patients with respiratory failure. Methods Forty patients with acute respiratory failure admitted in our hospital from January 2011 to January 2016 were divided into two groups according to the order of treatment. One group was treated with routine first aid method, one group Group was treated with non-invasive ventilator observation group, each group of 20 cases, the two groups of patients to observe the success rate of treatment, clinical symptoms improved. Results The success rate of treatment in the observation group was 95%, which was significantly higher than that in the control group (70%) (P<0.05). Before and after treatment, the clinical improvement of the observation group was better, Group, the difference was statistically significant (P<0.05). Conclusion Respiratory failure emergency treatment of patients using non-invasive ventilator, the success rate of clinical symptoms to improve the effect of good, with the promotion of value, it is worth promoting.
