棉絮加工女工肺通气功能分析

Analysis of Ventilation Function for Female Cotton Processer

本文对79名棉絮加工女工和73名对照女工的肺通气功能四项参数进行了对比分析,结果是(1)观察组的FEV_1、FEV_1/FVC、MMEF显著低于对照组,肺通气功能异常率明显高于对照组;(2)接尘工龄15年以上者FEV_1、FEV_1/FVC、MMEF显著低于低接尘工龄组,肺通气功能异常率明显高于低接尘工龄组;(3)接尘工龄15年以上者FEV_1、FEV_1/FVC、MMEF的异常率与对照组比较AR分别增加了15.15％、23.68％、25.48％,RR分别增加了4.22、5.09、4、66倍。

The ventilation function(FVC,FEV_1,FEV_1,/FVC,MMEF) of 79 femal cotton prccesors and 73 centrcls were analysed. The showed that the values of FEV_1/FEC,MMEF were significantly iewet and the rate of abnormal ventilation function were singnificantiy higher in cotton processors and the coiton processors who have worked for more than 15 years showed higher abnormal rate than who have worked for less years. The abnormal rates of FEV-1,FEV-1/FVC,MMEF in cotton processors Who have worked for more than 15 years were increased by 15.15％,23.68％,25.68％(AR) and 4.22,5.09, 4. 60 times (RR) than that of the conmol.
