Reproducibility of the parameters of bronchial patency was studied in 31 patients with nonspecific pulmonary diseases, changes in the parameters of bronchial patency during the berotek and loading tests--in 28 healthy subjects, the dynamics of bronchial patency in these tests and the value of separate methods of study of bronchial patency--in 119 patients with active pulmonary tuberculosis. The parameters of spirography, forced expiration flow-volume and general plethysmography were used. Assessment of the results of the pharmacological and loading tests require consideration of reproducibility of the parameters and their changes in healthy subjects in connection with a broncholytic action on the tone of bronchial muscles. The table of limited diagnostically insignificant functional changes in bronchial patency in given. When evaluating the results of functional tests, it is expedient to use a combination of the parameters of spirography, the curve of forced expiration flow-volume and general plethysmography and in the choice of method preference should be given to the registration of the curve of forced expiration flow-volume. The most sensitive parameters of the dynamics of bronchial patency in the broncholytic and loading tests have been developed.
对31例非特异性肺部疾病患者支气管通畅参数的可重复性进行了研究，对28例健康受试者在贝罗特克和负荷试验期间支气管通畅参数的变化进行了研究，对119例活动性肺结核患者在这些试验中支气管通畅的动态变化以及支气管通畅研究的不同方法的价值进行了研究。使用了肺量计、用力呼气流量-容积和总体积描记法的参数。药理学和负荷试验结果的评估需要考虑参数的可重复性及其在健康受试者中与支气管平滑肌舒张作用相关的变化。给出了支气管通畅有限的、诊断上无意义的功能变化表。在评估功能试验结果时，宜结合使用肺量计参数、用力呼气流量-容积曲线和总体积描记法，在方法选择上应优先选择记录用力呼气流量-容积曲线。已确定了支气管舒张和负荷试验中支气管通畅动态变化的最敏感参数。
