Effects of ACBT Technique Combined with Resistance Breathing Training on Patients with AECOPD
-
摘要:
目的 探讨主动呼吸循环技术(ACBT)联合抗阻呼吸训练对慢性阻塞性肺疾病急性加重期(AECOPD)患者的肺功能和运动能力的影响。 方法 选取2024年1月至2024年5月昆明某三甲医院老年医学科住院的AECOPD患者60例作为研究对象。采用随机数列方式,将患者分成两组,每组30例。对照组接受常规肺康复护理,观察组实施ACBT技术联合抗阻呼吸训练,出院后4周收集患者的肺功能指标、改良的英国医学委员会呼吸困难量表(mMRC)评分、6MWT距离、CAT量表评价干预效果。 结果 进行干预后,观察组的肺功能、mMRC得分、6MWT以及CAT量表的指标均比干预前有显著提升,且均优于对照组(P < 0.05)。 结论 ACBT技术联合抗阻呼吸训练能更有效促进AECOPD患者排出痰液,降低呼吸肌疲劳,增加活动耐力,改善呼吸困难程度及肺功能。 -

Abstract:Objective To investigate the effects of active respiratory circulation technique (ACBT) combined with resistance breathing training on pulmonary function and exercise capacity in patients with acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Methods A total of 60 hospitalized AECOPD patients from the Geriatrics Department of a tertiary hospital in Kunming were selected as research subjects from January to May 2024. Patients were randomly divided into two groups, with 30 patients in each group. The control group received conventional pulmonary rehabilitation nursing, and the observation group received ACBT combined with resistance breathing training. Pulmonary function indicators, modified British Medical Council(mMRC) dyspnea scores, 6-minute walk test (6MWT) distances, and the COPD Assessment Test (CAT) scores were collected 4 weeks after discharge to evaluate the intervention's effectiveness. Results After the intervention, the observation group showed significant improvements in lung function, mMRC scores, 6MWT distances, and CAT scores compared to pre-intervention levels, and all were superior to the control group (P < 0.05). Conclusion ACBT combined with resistance breathing training can more effectively promote sputum clearance, reduce respiratory muscle fatigue, increase exercise endurance, and improve dyspnea severity and lung function in AECOPD patients. -
