双水平气道正压通气治疗慢性阻塞性肺疾病合并冠心病患者呼吸衰竭的临床研究

目的 探讨应用双水平气道正压（BiPAP）通气治疗慢性阻塞性肺疾病（COPD）合并冠心病患者呼吸衰竭的疗效及对循环系统的影响。方法 将合并有冠心病的COPD呼吸衰竭患者随机分为2组，常规治疗组予以常规治疗，BiPAP治疗组在常规治疗基础上应用BiPAP通气治疗，观察2组疗效及病情变化。结果 BiPAP通气治疗组疗效明显优于常规组，尤其能使动脉二氧化碳分压下降，且对血流动力学无明显影响。结论 BiPAP通气治疗是COPD合并冠心病患者呼吸衰竭的有效治疗方法，且不会使冠心病病情恶化。

Bilevel positive airway pressure ventilation in patients with chronic obstructive pulmonary disease complicated by coronary heart disease

Objective To evaluate the application of Bilevel positive airway pressure (BiPAP) in chronic obstructive pulmonary disease(COPD) complicated by coronary heart disease patients and to study the effect on circulation system.Methods 42 patients with COPD complicated by coronary heart disease were randomly divided into two groups.17 patients in control group were treated by routine therapy while 25 patients in treatment group,based on routine therapy,were treated by BiPAP.The therapeutic effect and disease condition were observed.Results The therapeutic effect in treatment group was obviously superior to that of control group,especially the PaCO2 was decreased without effect on hemodynamics.Conclusion BiPAP is the effective way to treat COPD complicated by coronary heart disease,which also can not aggravate the coronary heart disease.
