尘肺患者肺功能分析

Pulmonary Function in 238 Patients With Pneumoconiosis

目的探讨尘肺病患者肺功能损伤特点及影响因素。方法用成都日升公司RSFJ-900型肺功能测定仪对238名尘肺病患者进行肺功能测定并对测定结果进行分析。结果238例尘肺患者的肺功能FVC、FEV1.0、FEV1.0%实测值与预测值的比值分别为78.2%、50.6%、53.7%,差异有统计学意义(P<0.05);不同期别、不同年龄组和吸烟与非吸烟组的肺功能损伤程度差异有统计学意义(P<0.05)。结论尘肺病可引起患者肺功能损害,随着病程的进展和年龄的增长损害加重,吸烟对尘肺病患者的肺功能损害有协同效应。

Objective To investigate the injury characteristics and influence factors of pulmonary function in patients with pneumoconiosis, and to provide prevention and cure measures. Method The pulmonary function in 238 patients with pneumoconiosis were measured and ahalyzed. Results The results showed that the ratios of the measured value to standard expected value of FVC, FEV1.0, FEV1/FVC% were 78.2%,50. 6%, and 53.7% separately, indicating that these patients＇ pulmonary function had descended obviously （P 〈 0. 05）. The results also showed that smoking, age and the course of pneumoconiosis were the most important factors to the damage of pulmonary function. Conclusion Pulmonary function in patients with pneumoconiosis can result in damage. With the progress of disease and age increase and smoking, the damage was aggravated.
