肺功能测验在尘肺防治工作中已广泛应用,常用肺功能降低程度作为尘肺患者劳动力鉴定的评价。目前,国内外多限于以肺通气功能测验作为尘肺患者临床治疗的疗效观察指标之一。本文试图探讨柠檬酸铝治疗石棉肺14个月(二个疗程)后肺通气功能中,能反映小气道功能的 FEF25—75%和 FEF75—85%二项指标的变化状况。 Pulmonary function tests have been widely used in the prevention and treatment of pneumoconiosis, commonly used as a reduction in pulmonary function evaluation of labor appraisal of patients with pneumoconiosis. At present, at home and abroad are mostly limited to lung ventilation test as one of the efficacy indicators of clinical treatment of patients with pneumoconiosis. This article attempts to investigate the changes of the binominal indices of FEF25-75% and FEF75-85%, which reflect the function of small airways in the lung ventilation after 14 months (two courses) of citrate treatment of asbestosis in lungs.
