目的 分析对重症肺源性心脏病呼吸衰竭患者实施不同通气模式的临床治疗效果.方法 80例重症肺源性心脏病呼吸衰竭患者, 按照不同的通气模式分为研究组和对照组, 各40例.对照组进行有创通气治疗, 研究组进行有创无创序贯法通气治疗.比较两组患者的临床指标改善情况.结果 治疗后, 研究组动脉血氧分压(PaO2)、动脉血二氧化碳分压(PaCO2)均优于对照组(P<0.05), 两组的pH值比较, 差异无统计学意义(P>0.05);研究组的机械通气时间、平均住院时间短于对照组(P<0.05);研究组的肺炎发生率5%低于对照组的20%(P<0.05).结论 应用有创无创序贯通气法治疗重症肺源性心脏病呼吸衰竭, 可有效改善患者的临床指标, 加快机体功能的恢复速度, 临床应用效果良好.%Objective To analyze clinical effects by different ventilation modes for patients with respiratory failure and severe pulmonary heart disease.Methods A total of 80 patients with respiratory failure and severe pulmonary heart disease were divided by different ventilation modes into research group and control group, with 40 cases in each group. The control group received invasive ventilation for treatment, and the research group received sequential treatment by invasive and non-invasive ventilation. Improvements of clinical indexes were compared between the two groups.Results After treatment, the research group had all better arterial partial pressure of oxygen (PaO2) and arterial partial pressure of carbon dioxide (PaCO2) than the control group (P<0.05). There was no statistically significant difference of pH value between the two groups (P>0.05). The research group had shorter mechanical ventilation time and average hospital stay time than the control group (P<0.05). The research group had lower incidence of pneumonia as 5% than 20% of the control group (P<0.05).Conclusion Application of sequential treatment by invasive and non-invasive ventilation in treating respiratory failure and severe pulmonary heart disease can effectively improve clinical indexes and accelerate body function rehabilitation in patients. This method shows remarkable clinical application effect.
