[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12 h后治疗组患者PaO2、PaCO2、pH基本恢复正常，与对照组比较有统计学差异(t=3.428、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。

[Abstract] Objective To explore the clinical effect of acute left ventricular failure with noninvasive positive pressure ventilator(ALVF). Methods 86 cases of ALVF patients from my hospital in March 2010—2012 year in March were randomly divided into control and treatment group，each of 43 cases. Control group were used conventional methods of anti—heart failure treatment；the treatment of patients in the control group were used on the basis of bi—level positive airway pressure(BiPAP) treated with mechanical ventilation，two groups were compared blood gas analysis and treatment efficiency. Results Before treatment，patients were arterial blood gas analysis showed no statistical difference in the treatment of 12 h in patients treated with the PaO2 PacO2，pH back to normal，compared with control group significant difference(t = 3 ......
