目的:总结无创正压通气对慢性阻塞性肺病急性加重期合并Ⅱ型呼吸衰竭的治疗效果。方法:应用BiPAP呼吸机对45例慢性阻塞性肺病急性加重期合并Ⅱ型呼吸衰竭患者进行通气治疗,观察治疗前后2小时、1天、2天的心率(HR),呼吸频率(RR)及血气变化。结果:治疗后血气指标PaO2、SaO2明显上升,PaCO2明显下降,HR,RR明显改善。结论:BiPAP呼吸机治疗慢性阻塞性肺病急性加重期合并Ⅱ型呼吸衰竭患者疗效显著,且对RR,HR明显改善的患者预后较好。
Objective: To summarize the therapeutic effect of noninvasive positive pressure ventilation on type Ⅱ respiratory failure in acute exacerbation of chronic obstructive pulmonary disease. Methods: Forty-five patients with acute exacerbation of chronic obstructive pulmonary disease and type Ⅱ respiratory failure were ventilated with BiPAP ventilator. The heart rate (HR), respiratory rate (RR) and blood gas were observed at 2 hours, 1 day and 2 days before and after treatment. Variety. Results: After treatment, blood gas indexes PaO2 and SaO2 increased significantly, PaCO2 decreased obviously, HR and RR improved obviously. Conclusion: BiPAP ventilator is effective in patients with acute exacerbation of chronic obstructive pulmonary disease and type Ⅱ respiratory failure, and has a good prognosis in patients with significantly improved RR and HR.
