探讨体描法气道阻力测定的异常发生率及其指标的临床异常值应用价值。 [方法 ]对 31 7例矽肺患者进行用力呼气量 [FEV:FVC%、FEV1 .0 %、(FEV1 .0 / FVC% ) ]及体描法气道阻力测定 [Raw(气道阻力 ) %、s Raw(比气道阻力 ) %、Gaw(气道传导率 ) %、s Gaw(比气道传导率 ) % ]。并比较其气道阻塞性障碍各项指标的异常发生率。 [结果 ]FEV1 .0 %、(FEV1 .0 / FVC) %异常发生率分别是 75 .71 %、41 .0 1 %。 Raw%、s Raw%、Gaw%、s Gaw%异常发生率分别是 71 .6 1 %、6 9.40 %、78.2 3%、75 .39%。约 70 %左右的矽肺患者有较明显的阻塞性通气功能障碍 ,其异常发生率随矽肺期别上升而增高。FEV1 .0 %与 s Gaw%两项测定的符合率为 87.0 7%。 [结论 ]在临床判断患者有无气道阻塞性通气功能障碍及阻塞程度方面 ,体描法气道阻力测定不仅较 FEV1 .0 %更为直接 ,且更具敏感性和客观性 ,其指标异常值可行。两者联合应用于矽肺患者肺功能检测可取得互补效果。
To explore the abnormal incidence of airway resistance measurement and its clinical value of abnormal value. [Method] The forced expiratory volume (FEV: FVC%, FEV1.0%, FEV1 .0 / FVC%) and physical airway resistance measurement (Raw, airway resistance) were measured in 317 patients with silicosis. s Raw%, Gaw%, s Gaw%. And compare the abnormal incidence of various indicators of airway obstruction. [Results] The incidences of FEV1 .0% and (FEV1 .0 / FVC)% were 75.71% and 41.0%, respectively. Raw%, s Raw%, Gaw%, s Gaw% abnormal rates were 71.61%, 69.40%, 78.2%, 75.39%, respectively. About 70% of patients with silicosis have more obvious obstructive ventilatory dysfunction, the abnormal incidence of silicosis increased with the rise. The coincidence rate between FEV1.0% and s Gaw% was 87.0 7%. [Conclusion] The physical tracing method of airway resistance was not only more direct and more sensitive and objective than the FEV1.0% in judging whether patients had airway obstructive ventilatory dysfunction and obstruction, feasible. The combination of the two in the detection of lung function in patients with silicosis can achieve complementary effects.
