目的:探讨无创正压通气治疗慢性阻塞性肺疾病合并呼吸衰竭的临床疗效。方法:选择符合条件的患者80例,随意分为观察组和对照组各40例,分别行无创正压通气治疗和常规治疗,比较两组患者PaCO2及PaO2水平,生命体征及呼吸指标改变情况结果:治疗后所有患者心率均减慢,呼吸由浅变深,胸闷气短、意识障碍等症状均有不同程度改善。观察组PaO2、PaCO2、动脉血pH值治疗后改善相比对照组更明显,差异有显著统计学意义(P<0.01)。结论:无创正压通气治疗慢性阻塞性肺疾病合并呼吸衰竭效果较好,使用安全,作用稳定持久,适应范围较广,对本病治疗有较大价值,值得临床推广。
Objective: To investigate the clinical effect of noninvasive positive pressure ventilation on chronic obstructive pulmonary disease with respiratory failure. Methods: 80 eligible patients were randomly divided into observation group and control group, 40 cases were treated with noninvasive positive pressure ventilation and routine treatment, PaCO2 and PaO2 levels were compared between the two groups, the changes in vital signs and respiratory index results : After treatment, all patients with heart rate were slowed down, breathing from shallow to deep, chest tightness, shortness of breath, unconsciousness and other symptoms have varying degrees of improvement. The observation group PaO2, PaCO2, arterial blood pH after treatment more obvious improvement compared with the control group, the difference was statistically significant (P <0.01). Conclusion: Noninvasive positive pressure ventilation is effective in treating chronic obstructive pulmonary disease combined with respiratory failure. It is safe to use, stable in function and long in duration and has a wide range of application. It is of great value to the treatment of this disease and is worthy of clinical promotion.
