目的探讨BiPAP呼吸机治疗慢性阻塞性肺疾病(COPD)并发Ⅱ型呼吸衰竭的疗效。方法比较分析62例COPD并发Ⅱ型呼吸衰竭病人经常规治疗(对照组)和加用BiPAP呼吸机治疗(实验组)的临床疗效。结果对照组仅动脉氧分压(PaO2)较治疗前有显著性差异(P<0.05),而实验组在pH、PaO2、动脉二氧化碳分压方面均较治疗前有极显著性改善(P<0.01)。结论BiPAP呼吸机能明显改善Ⅱ型呼吸衰竭病人的低氧血症及高碳酸血症,是治疗COPD并发Ⅱ型呼吸衰竭的有效措施。
Objective To investigate the efficacy of BiPAP ventilator in the treatment of chronic obstructive pulmonary disease (COPD) complicated with respiratory failure. Methods The clinical effects of routine treatment (control group) and BiPAP ventilator (experimental group) in 62 COPD patients with type Ⅱ respiratory failure were compared and analyzed. Results In the control group, only PaO2 was significantly lower than that before treatment (P <0.05), while the experimental group had a significant improvement in pH, PaO2 and arterial carbon dioxide partial pressure (P <0.01) ). Conclusion BiPAP respirator can significantly improve the hypoxemia and hypercapnia in type Ⅱ respiratory failure patients. It is an effective treatment for COPD complicated with type Ⅱ respiratory failure.
