  • 高频胸壁振荡排痰仪用于慢性阻塞性肺疾病和肺部感染患者排痰效果评价

    目的 评估高频胸壁振荡排痰仪的排痰效果以更好应用于临床。 方法 将2010年5月11月收治的60 例慢性阻塞性肺疾病和肺部感染患者随机分为高频振荡排痰组和振动排痰组。观察比较两组患者接受排痰治疗后第1、2、3天的日排痰量,每次操作前后指尖的血氧饱和度(SpO2)。 结果 高频振荡排痰组日排痰量及操作前后SpO2变化比值大于振动排痰组(P<0.05)。 结论 高频胸壁振荡排痰仪能有效促进患者痰液排出,减少护士工作量,其排痰效果优于振动排痰仪。

  • 振动排痰与人工排痰在老年慢性阻塞性肺疾病急性发作中的效果比较

    目的了解振动排痰在老年慢性阻塞性肺疾病急性发作(AECOPD)患者中的应用效果。 方法随机将2012年1月-12月住院治疗的80例老年AECOPD患者分为2组,分别采用振动排痰及人工排痰方式予以干预,并就两种干预方式的效果进行观察比较。 结果1周后,振动排痰组和人工排痰组排痰总有效率分别为97.5%和80.0%,两组比较差异有统计学意义(χ2=6.135,P=0.013);振动排痰组患者咳嗽减轻、呼吸困难消失时间分别为(3.2±1.7)、(2.9±1.3)d,均低于人工排痰组[(4.3±1.6)、(3.8±1.2)d],两组比较差异有统计学意义(P<0.05)。 结论振动排痰能有效促进老年AECOPD患者分泌物及痰液的排除,缩短患者咳嗽、呼吸困难症状的时间。

  • A comparative study between high-frequency chest wall oscillation expectoration and mechanical vibration expectoration in elderly patients with pulmonary infection

    Objective To compare the effect of high-frequency chest wall oscillation (HFCWO) expectoration and mechanical vibration (MV) expectoration in elderly patients with pulmonary infection. Methods Thirty elderly patients with pulmonary infection were randomly divided into a HFCWO group and a MV group with 15 patients in each group. On the basis of routine treatment, the HFCWO group was treated with HFCWO vest to help expectoration, and the MV group underwent traditional mechanical vibration to help expectoration. The respiratory rate, peripheral oxygen saturation (SpO2), activities of daily living (ADL) score were measured before treatment (D1), 7 days (D7), and 14 days (D14) after treatment. Results Except ADL score had no difference between D7 and D14 in the MV group, there were significant differences in daily amount of sputum, respiratory rate, SpO2, ADL score between D1, D7, and D14 in both groups (P<0.05). There were no significant differences in daily amount of sputum between two groups on D1, D7, or D14. SpO2 and ADL score were significantly higher in the HFCWO group on D7 and D14 compared with the MV group (P<0.05). Conclusions Both high-frequency chest wall oscillation and mechanical vibration are effective in improving expectoration. The HFCWO vest is superior in improving blood oxygen and relieving shortness of breath than mechanical vibration expectoration.

  • Arterial blood gas and clinical efficacy of respiratory training based on mechanical vibration-assisted expectoration in chronic obstructive pulmonary type 2 respiratory failure

    Objective To explore the effect of respiratory training based on mechanical vibration-assisted sputum expulsion on arterial blood gases in patients with chronic obstructive pulmonary type 2 respiratory failure and clinical efficacy observation. Methods 105 patients with chronic obstructive pulmonary disease combined with type 2 respiratory failure who were hospitalized in our hospital from November 2019 to February 2023 were selected as study subjects. They were randomly numbered and divided into experimental and control groups according to the order of admission, and 3 patients withdrew from the study cohort due to their own reasons, and 51 cases each of the experimental and control groups were finally included. Patients in the control group were given conventional treatment and lung function exercise, while the experimental group was given respiratory training with mechanical vibration-assisted sputum expulsion. Lung function and blood gas analysis indexes were measured before and 2 weeks after treatment to evaluate the clinical efficacy and incidence of adverse events in the two groups. Results After the treatment, pulmonary function indexes such as PEF, FVC, FEV1 and FEV1/FVC, and blood gas analysis indexes such as PaO2, PaCO2 of the experimental group and daily sputum excretion improved significantly compared with those of the pre-treatment and control groups (P<0.05). The total clinical efficacy rate of the patients in the experimental group was significantly higher than that of the control group (P<0.05), and the incidence of adverse events was lower than that of the control group, but the difference was not statistically significant (P>0.05). Conclusion Respiratory training based on mechanical vibration-assisted sputum expectoration can help improve the lung function and blood gas level of patients with chronic obstructive pulmonary disease combined with type 2 respiratory failure, and it has a certain clinical value in promoting the rehabilitation and prognosis of patients.
