测定38例临床症状缓解期哮喘患者的FEVl%等11项肺功能指标。结果表明大多数(>70%)的患者仍存在较明显的肺功能异常,其中,气道功能障碍甚于肺容量功能障碍;小气道功能障碍甚于大气道功能障碍。小气道功能障碍与患者哮喘病程的长短呈正相关。
Eleven pulmonary function indexes such as FEVl% were determined in 38 patients with clinical symptoms and remission. The results showed that most of the patients (> 70%) still had more obvious pulmonary dysfunction. Among them, airway dysfunction was more than pulmonary capacity dysfunction; small airway dysfunction was worse than airway dysfunction. Small airway dysfunction and the duration of asthma patients was positively correlated.
