The morphology of the lungs and heart was analysed in 824 newborn infants with normal cardiorespiratory adaptation. Under normal conditions, the air content of the lungs became satisfactory in the first 6--12 hours and normal in all cases after 24 hours. The values for the transverse diameter of the chest and heart were brought into correlation with birth weight, body length and gestational age. The transverse diameter of the chest and heart did not change during the early postnatal period (between 6--12 hours and 5 days). Both diameters were correlated with birth weight. The closest correlation was found in newborns under 1500 g, a varying one in those between 1500 and 2000 g and a close correlation in the category over 2000 g. The correlation of the two diameters with both length was linear and close, without any difference between the values obtained at different times of examination. A rather loose correlation was found between the transverse diameter of the chest and heart, and gestational age.
对824例具有正常心肺适应能力的新生儿的肺和心脏形态进行了分析。在正常情况下，肺的含气量在出生后的最初6 - 12小时内达到满意水平，24小时后所有病例均恢复正常。将胸围和心脏横径的值与出生体重、身长和胎龄进行相关性分析。出生后早期（6 - 12小时至5天）胸围和心脏横径未发生变化。两者直径均与出生体重相关。在体重低于1500克的新生儿中发现相关性最强，在体重介于1500至2000克之间的新生儿中相关性各异，而在体重超过2000克的类别中相关性密切。两直径与身长的相关性呈线性且密切，不同检查时间所获数值之间无差异。胸围和心脏横径与胎龄之间的相关性较为松散。
