目的 :观察呼吸操对慢性阻塞性肺病 (COPD)患者血气的影响和对缺氧的耐受能力以及对肺功能的影响。方法 :测定 2 0例 COPD急性发作期患者经缩唇呼吸治疗 2 0 min前后的血气变化 ;在做或不做呼吸操状态下分别测定 2 0例 COPD慢性迁延期患者行走活动 6 min后的血气以及在 Sa O2 下降 2 %时的行走活动距离 ;测定 2 0例 COPD缓解期患者经长期呼吸操锻炼前后肺功能的变化。结果 :呼吸操锻炼后对 COPD急性期和迁延期患者的 Pa O2 、 Sa O2 均有显著改善 ,缓解期患者的肺功能亦有显著增高。结论 :呼吸操能改善 COPD患者的血气 ,长期锻炼可以改善其肺功能和生活质量
Objective: To observe the effects of breathing exercises on the blood gas of patients with chronic obstructive pulmonary disease (COPD), the tolerance to hypoxia and the effects on lung function. Methods: Twenty patients with acute exacerbation of chronic obstructive pulmonary disease (COPD) were treated with deflated liposuction for 20 minutes before and after treatment. The blood gas was measured in 20 patients with COPD for 6 min And walking distance at 2% decrease of Sa O2. The changes of pulmonary function in 20 COPD patients before and after prolonged breathing exercises were measured. Results: PaO2 and Sa O2 were significantly improved in patients with COPD in acute phase and extended phase after respiratory exercises, and lung function was also significantly increased in patients with remission. Conclusion: Breathing can improve blood gas in COPD patients. Long-term exercise can improve lung function and quality of life
