Impact of Dust Weather on Pulmonary Function of People with Different Exposure Times

Objectives  To master the state of pulmonary function and the type of pulmonary ventilation dysfunction in staffs of a Xinjiang Production and Construction Corps and Pishan Farm, and to discuss the impact of age, the length of time for dust exposure, occupation and cardiopulmonary complications on pulmonary ventilation function.

Methods  A CHESTGRAPH HI-101 pulmonary function analyzer made in Japan Jie Site was used to measure the pulmonary ventilation function.The medical history, chest X-ray, ECG, symptoms and physical signs were analyzed and compared.

Results  There were 107 cases suffered from pulmonary ventilation dysfunction in 519 staffs examined by Kruskal Wallis test, accounting for 23.21%. The indexes of pulmonary ventilation function such as FVC, FEV₁, FEV_1.0% (FEV₁/FVC%), MMF, FEF25, FEF50, FEF75 checked against each other show significant differences (P less than 0.001), especially the maximal mid-expiratory flow (FEF).

Conclusions  The pulmonary ventilation dysfunction was mainly restrictive ventilator dysfunction, which was closely related to field labor, old age, indigenous resident, lower educational level, suffered from emphysema, pulmonary heart disease (PHD), frequent colds, rhinitis, chronic pneumonia, and the like.
