矽尘作业工人及矽肺患者的通气功能国内外屡有报告,但由于检查对象不同,所用仪器不同而每有差异。我们这次对137名接触矽尘工人及53名各期矽肺患者进行通气功能测定,通过各种通气功能的比较,期以阐明矽肺时各种通气功能的改变及最大呼气中期流速在矽肺 Ventilation function of silica dust workers and silicosis patients has been repeatedly reported at home and abroad, but due to the different objects of inspection, the instruments used vary from one to another. We conducted 137 ventilator tests on silicosis workers and 53 patients with silicosis for ventilatory function tests. By comparing various ventilatory functions, we clarified the changes in various ventilatory functions and the maximum expiratory mid-term flow rate in silicosis
