无创正压呼吸机辅助治疗慢性阻塞性肺疾病合并呼吸衰竭的疗效观察

目的探讨（鼻）面罩多功能双水平无创正压通气辅助治疗慢性阻塞性肺疾病合并呼吸衰竭的作用。方法40例慢性阻塞性肺疾病急性加重期合并呼衰患者，分为常规治疗组及应用双水平无创正压呼吸机辅助通气治疗组，记录通气各组治疗前后血气及心率（HR）变化。结果经双水平无创正压呼吸机辅助通气治疗组的临床症状改善和血气分析指标恢复正常，与常规治疗的对照组比较差异有统计学意义（P〈0．01）。同时治疗组间差异均有统计学意义（P〈0．05）。结论应用多功能双水平无创呼吸机辅助通气治疗慢性阻塞性肺疾病合并呼吸衰竭效果肯定，可明显提高患者血气的PH值及PaO2，同时可降低PaCO2，使患者通气功能和缺氧体征得到明显的改善。

To Investigate the (nasal) Mask Bi-Level Multi-Functional Noninvasive Positive Pressure Ventilation,Auxiliary Treatment of Chronic Obstructive Pulmonary Disease with Respiratory Failure Role

Objective To investigate the （nasal） mask bi -level multi -functional noninvasive positive pressure ventilation, auxiliary treatment of chronic obstructive pulmonary disease with respiratory failure role. Methods 40 cases of chronic obstructive pulmonary disease with acute exacerbation of respiratory failure in patients with the merger, divided into conventional treatment group and application of bi - level noninvasive positive pressure ventilation in the treatment of ventilator - assisted group, Record ventilation in each group before and after treatment of blood gas and heart rate （HR） changes. Results The bi -level noninvasive positive pressure ventilator -assisted ventilation in the treatment group to improve the clinical symptoms and blood gas analysis indicators returned to normal, and conventional treatment control group difference was significant （ P 〈 0. 01 ）. At the same time, differences between the treatment group were significantly （ P 〈 0.05）. Conclusion Application of multi - function bi - level non - invasive ventilator - assisted ventilation in the treatment of chronic obstructive pulmonary disease with respiratory failure effect and can significantly improve in patients with PH value of blood gas PaO2, at the same time can reduce the PaCO2, so that patients with hypoxic ventilatory function and the signs have been significantly improved.
