Ⅰ期煤工尘肺患者肺功能与血气测定结果分析
Journal of Occupational Health and Damage(2009)
Abstract
目的探讨肺功能与血气分析测定对Ⅰ期煤工尘肺患者致残等级鉴定的影响。方法通过56例Ⅰ期煤工尘肺患者肺功能测定与血气分析测定,比较肺功能损伤结果。结果56例Ⅰ期煤工尘肺患者肺功能FVC、FEV1、MVV的损伤率均达85%以上,且中度和重度损伤率FVC为51.79%;FEV1为62.50%;FEV1/FVC为30.36%;MVV为46.43%。血气分析结果,PO2正常率为57.14%,轻度低氧血症为42.86%,无1例达到中度和重度低氧血症标准。结论肺功能检查受人为因素影响较大,应加强对肺功能检查的质量控制,提高肺功能检查的准确性。对尘肺患者进行致残等级鉴定应当结合肺功能检查和血气分析结果,综合评定肺功能损伤程度。
