Planimetric measurements of total lung capacity (TLC) were made from posteroanterior and lateral chest roentgenograms obtained during a nationwide survey of the civilian, noninstitutionalized United States population. Regression equations for TLC, residual volume (RV), and the ratio of RV to TLC for healthy, nonsmoking participants are presented. The equations predict values that agree closely with previously published normal values obtained by other methods.
在美国全国范围内对非住院平民人口进行的一项调查中，通过后前位和侧位胸部X线片对总肺容量（TLC）进行了平面测量。文中给出了健康、不吸烟参与者的TLC、残气量（RV）以及RV与TLC比值的回归方程。这些方程预测的值与之前通过其他方法公布的正常值非常吻合。
