Disruption of normal respiratory function is associated with occupational disorders. Exposure to welding fumes on long term basis affects the lung function of the workers and prompts allergic responses. Therefore, the aim of the study was to manifest the association of exposure to welding fumes and respiratory complications with reference to the undermining of normal lung function and respiratory symptoms. A cross sectional study was conducted in different areas of Lahore in 2016. A comparison was made among welders on the basis of lung function and other physical ailments. Questionnaire survey was performed along with the computation of lung function by using spirometer. Data was statistically analyzed by using analysis of variance (ANOVA). The study confirmed a statistically highly significant decline in FVC, FEV1, FEF 25-75%, PEFR and FEV1/FVC ratio among different types of welders. The current study expressed that occupational exposure to welding fumes can considerably distress the lung function. The application of preventive measures is required to solve the health related questions for welders.
正常呼吸功能的破坏与职业性疾病有关。长期接触焊接烟雾会影响工人的肺功能并引发过敏反应。因此，本研究的目的是参照正常肺功能和呼吸道症状的损害，阐明接触焊接烟雾与呼吸道并发症之间的关联。2016年在拉合尔的不同地区进行了一项横断面研究。根据肺功能和其他身体疾病对焊工进行了比较。通过问卷调查并使用肺活量计计算肺功能。数据采用方差分析（ANOVA）进行统计学分析。该研究证实，不同类型焊工的用力肺活量（FVC）、第一秒用力呼气容积（FEV1）、25%-75%用力呼气流量（FEF 25-75%）、呼气峰值流速（PEFR）和FEV1/FVC比值在统计学上有极显著下降。本研究表明，职业性接触焊接烟雾会严重损害肺功能。需要采取预防措施来解决焊工的健康相关问题。
