为评价气道阻塞的肺功能与肺过度膨胀的形态学标准间关系,本文对98例胸片无明显其他异常的老年慢性阻塞性肺病患者的肺功能与胸片测量作了统计学观察,发现两者密切相关:(1)左侧位胸片上右膈弧高≤2.1cm时,93.5％患者肺功能异常,其中44.2％为重度障碍;(2)后前位胸片上右肺长≥26.2cm时,87.5％患者肺功能异常,其中71.4％为重度障碍。因此,对胸片作简单的测量将有助判断老年人慢性阻塞性肺病是否有肺功能障碍。
In order to evaluate the relationship between airway obstruction and lung morphological criteria of over-expansion, we performed a statistical observation of pulmonary function and chest radiography in 98 patients with chest X-ray of other abnormalities without other abnormalities and found that The two are closely related: (1) 93.5% of patients with lung dysfunction on the left chest radiograph when the right phrenic arc height ≤ 2.1cm, of which 44.2% were severe; (2) the right lung length of the anterior chest radiograph ≥26.2cm , 87.5% of patients had abnormal lung function, of which 71.4% were severe. Therefore, a simple measurement of the chest radiograph will help determine whether COPD patients have pulmonary dysfunction.
