1、无创正压通气在治疗急性左心衰竭中应用观察［摘要］目的探讨无创正压通气呼吸机治疗急性左心衰竭(ALVF)患者的临床效果。方法将我院2010年3月〜2012年3月收治的86例ALVF患者随机分为对照组和治疗组,各43例。对照组采用常规抗心衰的方法进行治疗；治疗组患者在对照组的基础上采用双水平气道正压通气(BiPAP)机械通气治疗，比较两组患者治疗前后血气分析情况及治疗的总有效率。结果治疗前两组患者动脉血气分析比较无统计学差异，治疗12h后治疗组患者Pa02、PaC02、pH基本恢复正常，与对照组比较有统
2、计学差异(23.428、2.835、2.307,P〈0.05)。对照组中痊愈13例，显效10例，有效7例，无效13例，总有效率为69.8%；治疗组中痊愈19例，显效13例，有效6例，无效5例，总有效率为88.4%,两组比较差异有统计学意义(P<0.05)。结论双水平气道正压通气(BiPAP)机械通气法治疗ALVF效果十分明显，值得临床进一步使用和推广。［关键词］双水平气道正压通气；左心衰竭［中图分类号］R541.6［文献标识码］B［文章编号］1673—9701(2012)27—0159—02Obse
