The specific airways conductance (SGAW) of 23 patients with copious sputum production and airflow obstruction was measured before and after physiotherapy to determine the effect of bronchial secretions on pulmonary function. Chest physiotherapy to remove these secretions had the effect of reducing airflow obstruction, as measured by SGAW. These findings suggest that sputum has a detrimental effect on pulmonary function and that physiotherapy can reduce airways obstruction.
对23例痰液大量生成且有气流阻塞的患者,在物理治疗前后测量其比气道传导率(SGAW),以确定支气管分泌物对肺功能的影响。通过SGAW测量发现,清除这些分泌物的胸部物理治疗具有减轻气流阻塞的作用。这些发现表明,痰液对肺功能有不利影响,且物理治疗可减轻气道阻塞。
