Examination Results of Pulmonary Ventilation Function of 94 Blasters with Silicosis

[Objective]To study the relationship between pulmonary function and staging silicosis. [Methods]Pulmonary function test instrument was used to measure FVC,FEV1,FEV1% of blaster with silicosis. [Results]Of 94 patients,59(62.8%) had abnormal pulmonary function.The case numbers and degree of abnormal pulmonary function in stage Ⅲ were higher than those of stage Ⅰ or Ⅱ,the difference between each stage was significant.The restrictive and FEV1 abnormal fall were more easily to observe in pulmonary function damage of Silicosis. [Conclusion]The severity and incidence of pulmonary function damage increases with the advancing of silicosis stage,especially for the patients with silicosis stageⅢ. The restrictive and FEV1 abnormal fall of pulmonary function damage were observed easily in this study.The silicosis patients with only FEV1 fall are advised to receive pulmonary diffusion function and other pulmonary function test.
