摘要
目的:探讨脉冲强迫振荡测定呼吸阻抗在肺结核患者中的应用。方法:用脉冲强迫振荡测试系统(IOS)对937例肺结核患者进行呼吸阻抗测定,并与常规肺功能比较,以及健康人脉冲振荡参数进行分析比较。结果:肺结核患者Zrs、R_5、X_5、Fres都与正常人有明显差异,其中响应频率(Fres)是肺结核患者肺功能损害最为敏感的指标。并且随结核病情严重程度的增加呼吸阻抗参数的异常率也升高。结论:呼吸阻抗测定对肺结核患者在临床诊断和治疗中有重要指导作用。
Objective: To study the applied value of impulse oscillation for measurement of respiratory impulse in the patients with pulmonary tuberculosis. Methods: The respiratory impedance in 937 patients with pulmonary tuberculosis was detected with impulse oscillation test system(IOS), and compared with the routine pulmonary function and the parameter of impulse oscillation in health person. Results: There was significat difference between patients with pulmonary tuberculosis and normal person in the total impedance(Zrs), the total airway resistance(R5), the peripheral capucitance(X5) and resonance fre-quenc.the frequency(Fres), among them resonance frequenc the frequency(Fres) was most sensitive index of pulmonary function damage in patients with pulmonary tuberculosis. The abnormal rate of respiratory impedance parameter was also increased along with the exacerbation of tuberculosis degree. Conclusion: The measurement of respiratory impedance has an important guiding role in clinical diagnosis and treatment of pulmonary tuberculosis.
