目的 探讨在冠脉搭桥手术后应用BiPAP无创通气对急性呼衰的治疗作用。方法 对32例冠脉搭桥手术后发生急性呼衰患者采用BiPAP呼吸机经面罩双水平气道正压通气，观察治疗前后血气分析的pH、PaO2、PaCO2、及SpO2和PaO2/FiO2指标变化。结果 BiPAP无创通气治疗后PaO2、SpO2、PaO2/FiO2均升高，PaCO2降低，pH改善，均有显著性差异（P<0.05）。结论 BiPAP呼吸机经面罩双水平气道正压通气治疗冠脉搭桥手术后急性呼衰疗效满意，无明显并发症，值得临床推广应用。

The clinical analysis on treatment of with CABG complicated by acute respiratory failure with BiPAP noninvasive ventilation
【Abstract】 Objective To investigate the therapeutical effect of bi-level positive airway pressure （BiPAP） noninvasive ventilation in the CABG with acute respiratory failure.Methods Before and after utilization of BiPAP ventilator，the blood gas parameters including pH,PaO2,PaCO2,SpO2,PaO2/FiO2were observed in the mode of positive airway pressure ventilation via facial mask in 32 patients with CABG with acute respiratory failure.Results Both of the values of PaO2 and SpO2 increased obviously,while the value of PaCO2 decreased obviously,and the value of pH improved significantly after utilization of BiPAP noninvasive ventilation.All the differences were statistically significant （P<0.05）.Conclusion Utilization of BiPAP ventilator via facial mask positive airway pressure ventilation in the CABG with CABG respiratory failure has a satisfactory therapeutic effect,without any obvious complications and deserves further clinical application.
