慢阻肺Ⅱ型呼吸衰竭患者使用简易呼吸训练器的价值

Value of simple respirator in COPD respiratory failure patients

目的探究慢性阻塞性肺疾病(COPD)Ⅱ型呼吸衰竭患者使用简易呼吸训练器进行呼吸功能锻炼对动脉血气及活动耐力的影响。方法2017—2020年间本院收治的40例COPDⅡ型呼吸衰竭患者进入研究,均分为参照组和研究组。参照组实施缩唇腹式呼吸,研究组添加简易呼吸训练器。比较两组治疗效果。结果研究组治疗后氧分压和二氧化碳分压水平更优(79.23±5.17 VS 89.76±6.21,41.36±4.18 VS 49.79±4.23),P<0.05。研究组患者治疗后用最大分钟通气量、第1秒用力呼气容积占预计值百分比均优于参照组(98.41±4.27 VS 85.74±4.58,83.17±4.89 vs 75.76±4.32),P<0.05。结论COPDⅡ型呼吸衰竭患者采用简易呼吸训练器治疗有效降低二氧化碳潴留,改善缺氧,提高活动耐力,改善临床症状,提高治疗有效率。

Objective To investigate the effects of simple breathing trainer on arterial blood gas and activity endurance in patients with type ii respiratory failure of chronic obstructive pulmonary disease(COPD).Methods From 2017 to 2020,40 patients with COPD type Ⅱ respiratory failure admitted to our hospital were enrolled into the study,which were divided into the reference group and the study group.The control group was given lip contraction abdominal breathing,and the study group was given a simple breathing trainer.The therapeutic effects of the two groups were compared.Results The oxygen partial pressure and carbon dioxide partial pressure were better in the study group(79.23±5.17 VS 89.76±6.21,41.36±4.18 VS 49).The percentage of maximal minute ventilation volume and forced expiratory volume in the first second in the predicted value of patients in the study group was better than that in the reference group(79.23±5.17 VS 89.76±6.21,41.36±4.18 VS 49.79±4.23),P<0.05.Conclusion Patients with COPD type Ⅱ respiratory failure treated with simple breathing trainer can effectively reduce carbon dioxide retention,improve hypoxia,improve activity endurance,improve clinical symptoms and improve treatment efficiency.
