渗出性结核性胸膜炎对呼吸阻抗的影响

目的：探讨渗出性结核性胸膜炎（胸腔积液）对呼吸阻抗的影响，评价脉冲振荡法（IOS）测定渗出性结核性胸腔炎（胸腔积液）患者呼吸阻抗的临床意义；方法：测定、分析40例健康人和71例渗出性结核性胸膜炎（胸腔积液）患者的各项IOS指标，同时测定传统通气功能。IOS结果作t检验；结果：与健康组比较，渗出性结核性胸膜炎（胸腔积液）患者共振频率增高，呼气未阻力增高，电抗下降；结论：IOS法测定呼吸阻抗在渗出性结核性胸膜炎（胸腔积液）临床应用中有一定的价值。

The effect of exudative tuberculosis pleurisy on the respiratory impedance

Objective To discuss the effect of exudative tuberculosis pleurisy (pleural effusion) on respiratory impedance and to evaluate the clinical significance of impulse oscillation (IOS) to determine the respiratory impedance the patients with exudative tuberculosis pleurisy (pleural effusion).Methods The IOS indices of 40 normal cases and 71 cases of exudative tuberculosis pleurisy (pleural effusion) were measured and traditional lung function was measured the same time t-test was pursued with the IOS.Results Compared with normal cases, the resonance frequency of the 71 patients with exudative tuberculosis pleurisy (pleural effustion) increased.The resistance increased and reactance descended in end-inspiration.Conclusion Theapplied foreground of IOS in clinical exudative tuberculosis pleurisy (pleural effusion) could be good.
