The pulmonary function has been studied by several methods using radioactive gases since 1955. Knipping and col. reported the first study with 133Xe in the evaluation of the gas distribution in pulmonary ventilation. In this study, we report the pulmonary function in 40 normal persons, evaluated by injection in a peripherical vein of this radioactive substance. The elementary respiratory functions: ventilation, diffusion and perfusion were calculated by distribution curves of 133Xe and we obtained the V/P index is very important for the diagnosis and therapeutic evaluation of the pulmonary function. Comparative studies with several examples of human pulmonary disease are in progress in our laboratory.
自1955年以来，已经使用放射性气体通过多种方法对肺功能进行了研究。Knipping及其同事报告了第一项使用133Xe评估肺通气中气体分布的研究。在本研究中，我们报告了通过向外周静脉注射这种放射性物质评估的40名正常人的肺功能。通过133Xe的分布曲线计算基本呼吸功能：通气、扩散和灌注，并且我们获得了对肺功能诊断和治疗评估非常重要的V/P指数。我们实验室正在对几例人类肺部疾病进行比较研究。
