无创呼吸机在急性左心衰竭中的应用

目的评价双水平正压无创通气（BiPAP）救治急性左心衰竭的临床疗效。方法84例急性左心衰竭患者随机分为治疗组与对照组，治疗组在常规抗心衰治疗基础上联用BiPAP呼吸机面罩正压通气治疗，42例对照组为常规抗心衰治疗，观察治疗前、治疗后1h、6h的动脉血PaO2、SaO2、PaCO2，心率、呼吸、血压、24h后心功能改善情况。结果两组患者治疗前各指项比较差异无统计学意义（P〈0．05）。治疗组治疗后1h、6h的PaO2、SaO2、PaCO2，心率、呼吸、血压均较对照组明显改善（P〈0．05），24h心功能改善，有效率治疗组较对照组明显增高（95．24％ vs 71．43％，P〈0．05）。结论无创双水平正压通气对急性左心衰的治疗有一定效果。

Bi-level positive airway pressure non-invasive ventilation in the treatment of severe acute left ventricular failure

Objective To explore the therapeutic effect of bi-level positive airway pressure(BiPAP)non-invasive ventilation on severe acute left ventricular failure.Methods Eighty-four patients with acute left ventricular failure were divided into two groups at random.The patients were treated with BiPAP non-invasive ventilation in addition to conventional treatment in therapy group and with conventional treatment in control group.The PaO2,SaO2,PaCO2,heart rate,blood pressure,respiratory rate and heart function were ob...
