G-5振动排痰仪振动前胸部排痰及呼吸功能训练对慢性阻塞性肺气肿患者排痰效果及肺功能的影响

Effects of expectoration through vibrating anterior chest by G-5 vibration sputum extractor and respiratory function training on sputum excretion effect and pulmonary function of patients with chronic obstructive pulmonary emphysema

目的探究G-5振动排痰仪振动前胸部排痰及呼吸功能训练对慢性阻塞性肺气肿患者排痰效果及肺功能的影响。方法选取2017年2月至2019年3月本院收治的186例慢性阻塞性肺气肿患者,根据随机数表法将其分为观察组与对照组,各93例。对照组给予传统人工叩击排痰,观察组给予G-5振动排痰仪振动前胸部排痰以及呼吸功能训练。比较两组患者的排痰效果以及肺功能指标。结果干预后,两组患者的日均排痰量及痰液黏稠度评分均显著降低,且观察组低于对照组(P<0.05)。观察组的排痰总有效率明显高于对照组(P<0.05)。观察组干预后的FEV1/FVC、FEV1、PEF%pred、MMEF均高于对照组和干预前(P<0.05)。结论G-5振动排痰仪振动前胸部排痰及呼吸功能训练能提高慢性阻塞性肺气肿患者的排痰效果,改善其肺功能。

Objective To explore the effects of expectoration through vibrating anterior chest by G-5 vibration sputum extractor and respiratory function training on sputum excretion effect and pulmonary function of patients with chronic obstructive pulmonary emphysema.Methods A total of 186 patients with chronic obstructive pulmonary emphysema admitted in our hospital from February 2017 to March 2019 were selected and divided into observation group and control group according to the random number table method,with 93 cases in each group.The control group was given traditional manual percussion expectoration,while the observation group was given expectoration through vibrating anterior chest by G-5 vibration sputum extractor and respiratory function training.The expectoration effects and pulmonary function indexes of the two groups were compared.Results After intervention,the average daily sputum output and sputum viscosity scores of the two groups significantly decreased,and those of the observation group were lower than the control group(P<0.05).The total effective rate of expectoration in the observation group was significantly higher than that in the control group(P<0.05).The FEV1/FVC,FEV1,PEF%pred and MMEF in the observation group after intervention were higher than those in the control group and before intervention(P<0.05).Conclusion Expectoration through vibrating anterior chest by G-5 vibration sputum extractor and respiratory function training can improve sputum excretion effect and pulmonary function of patients with chronic obstructive pulmonary emphysema.
