目的探讨胸部叩击和气流震荡叠加主动周期性呼气对咳痰患者肺功能的影响。方法 90例肺部感染并伴有咳痰症状患者,根据其入院先后顺序分为对照组和观察组,各45例。对照组给予抗感染、祛痰等一般治疗,观察组在对照组治疗基础上给予胸部叩击及气流震荡叠加主动周期性呼气。两组患者均在治疗前后给予肺功能检测,以第一秒用力呼气容积(FEV1)为观察指标,观察两组患者FEV1的变化情况。结果治疗前两组患者FEV1实测值占预计值百分比分别为(76±7)%及(75±6)%,比较差异无统计学意义(P>0.05)。治疗后,两组FEV1实测值占预计值百分比分别为(83±5)%及(77±3)%,比较差异有统计学意义(P<0.05)。结论胸部叩击及气流震荡叠加周期性自主呼气对咳痰患者的肺功能恢复明显有效,能够促使患者肺功能好转。
Objective To investigate the effects of chest-tap and air-stream shock superimposed active cyclical expiration on pulmonary function in sputum patients. Methods Totally 90 patients with lung infection and sputum symptoms were divided into control group and observation group according to the sequence of their admission. The control group was given anti-infective, expectorant and other general treatment. The observation group was given thoracic tapping and air flow oscillation plus active cyclical expiration on the basis of the control group. Both groups were given pulmonary function tests before and after treatment. The first second forced expiratory volume (FEV1) was used as the observation index to observe the changes of FEV1 in both groups. Results The percentages of the predicted values of FEV1 in the two groups before treatment were 76 ± 7% and 75 ± 6%, respectively, with no significant difference (P> 0.05). After treatment, the percentages of the predicted values of FEV1 in the two groups were (83 ± 5)% and (77 ± 3)% respectively, with statistical significance (P <0.05). Conclusions Chest tapping and airflow turbulence combined with periodic spontaneous expiration are effective in the recovery of lung function of sputum in patients with sputum, which can promote the improvement of pulmonary function in patients.
