【摘 要】目的：呼吸重症监护室发生呼吸机相关性肺炎的危险因素分析。方法：选择在我院呼吸重症监护室治疗且实施机械通气的140例患者，研究对象筛选时间范围是2017年1月-2018年12月。观察本組患者呼吸机相关性肺炎发生情况，对危险因素进行分析。结果：本组患者呼吸机相关性肺炎发生率是25%，年龄超过70岁、超过5d的上机时间、处于昏迷、应用2种及以上抗生素、合并基础疾病是影响呼吸机相关性肺炎的危险因素，项目之间比较有统计学差异，P<0.05。结论：龄超过70岁、超过5d的上机时间、处于昏迷、应用2种及以上抗生素、合并基础疾病是影响呼吸重症监护室呼吸机相关性肺炎的危险因素，在护理过程，要予以重视，实施针对性预防，保障治疗安全性。
