负荷呼吸训练联合高纯度负氧离子对慢性阻塞性肺疾病患者肺功能及康复的影响

Effect of load breathing training combined with high-purity negative oxygen ions on lung function and rehabilitation in patients with chronic obstructive pulmonary disease

目的观察负荷呼吸训练联合高纯度负氧离子对慢性阻塞性肺疾病(COPD)患者肺功能及康复的影响。方法选取2021年1月至2022年11月江苏省无锡市第二人民医院收治的COPD患者150例,根据随机数字表法将其分为对照组和研究组,各75例。对照组给予6周负荷呼吸训练,研究组在对照组基础上予以2周的高纯度负氧离子治疗,观察并比较两组肺功能、血气指标、呼吸肌收缩力及康复指标。结果干预后,两组用力肺活量、最大通气量、第1秒用力呼气容积、血氧分压、血氧饱和度、最大吸气压等指标高于干预前,且研究组高于对照组(P<0.05),6分钟步行距离长于干预前,且研究组长于对照组(P<0.05),而二氧化碳分压、最大呼气压、COPD评估测试及改良英国MRC呼吸困难指数分级评分低于干预前,且研究组低于对照组(P<0.05)。结论对COPD患者采用高纯度负氧离子联合负荷呼吸训练有利于提高患者肺功能,改善呼吸肌力量,促进患者的快速康复。

Objective To observe the effect of load breathing training combined with high-purity negative oxygen ions on lung function and rehabilitation in patients with chronic obstructive pulmonary disease(COPD).Methods A total of 150 COPD patients were admitted to the Second People’s Hospital of Wuxi,Jiangsu Province from January 2021 to November 2022.According to the method of random number table,they were divided into control group and study group,with 75 cases in each group.The control group was given six weeks of loaded respiratory training,while the research group received an additional two weeks of high-purity negative oxygen ion therapy based on the treatment of the control group.The lung function,blood gas indices,respiratory muscle contractility,and rehabilitation indicators of both groups were observed and compared.Results After intervention,the forced vital capacity,maximum ventilation capacity,forced expiratory volume in one second,partial pressure of oxygen,oxygen saturation,maximum suction pressure,and other indicators of the two groups were higher than before intervention,and the study group were higher than the control group(P<0.05).The 6 min walking distance was longer than that before intervention,and that of the study group was longer than that of the control group(P<0.05).The partial pressure of carbon dioxide,maximum expiratory pressure,chronic obstructive pulmonary disease assessment test,and modified UK MRC respiratory difficulty index rating scale scores were lower than those before intervention,and those of the study group were lower than those of the control group(P<0.05).Conclusion High purity negative oxygen ion combined with load breathing training for COPD patients can improve the pulmonary function,improve the strength of respiratory muscles,and promote the rapid recovery of patients.
