自制简易呼吸锻炼装置在不能配合无创通气的Ⅱ型呼吸衰竭COPD患者中的应用

Application of homemade breathing exercises device in type Ⅱ respiratory failure COPD patients with failure non-invasive ventilation

目的分析自制简易呼吸锻炼装置改善不能配合无创通气的Ⅱ型呼吸衰竭慢性阻塞性肺疾病(COPD)患者呼吸功能的效果。方法 100例COPD并Ⅱ型呼吸衰竭且无法配合无创通气患者,随机分为对照组和观察组,各50例。对照组在药物治疗基础上进行腹式缩唇呼吸锻炼,观察组在药物治疗的基础上使用自制简易呼吸锻炼装置进行腹式缩唇吹气泡呼吸锻炼。对比两组治疗效果。结果两组治疗1周、1、3个月后的一秒用力呼气容积(FEV1)、6 min步行距离明显增加,且观察组增加程度明显高于对照组(P<0.05)。结论 COPD并Ⅱ型呼吸衰竭且无法配合无创通气的患者应用简易呼吸锻炼装置进行呼吸锻炼后,可显著改善肺功能与运动耐力。

Objective To analyze effect by homemade breathing exercises device in improving respiratory function in type Ⅱ respiratory failure chronic obstructive pulmonary disease （COPD） patients with failure non-invasive ventilation.Methods A total of 100 type Ⅱ respiratory failure COPD patients with failure non-invasive ventilation were randomly divided into control group and observation group, with 50 cases in each group. The control group received basic abdominal contraction lip breathing exercise, and the observation group received additional homemade breathing exercises device for abdominal contraction lip bubble blowing breathing exercise to drug therapy. Curative effects of the two groups were compared.Results Both groups had increased forced expiratory volume in 1 second （FEV1） and 6 min walking distance in 1 week, 1 and 3 months after treatment, and those in the observation group were higher than the control group （P〈0.05）.Conclusion Implement of homemade breathing exercises device can remarkably improve pulmonary function and exercise tolerance in type Ⅱ respiratory failure COPD patients with failure non-invasive ventilation.
