Lung mechanics and partial forced expiratory flows were measured serially in seven normal infants during the first year of life. Lung mechanics were measured by the end inspiratory occlusion technique and partial forced expiratory flows by the rapid chest compression method. Thoracic gas volume, compliance, and partial forced expiratory flows measured at functional residual capacity progressively increased with age and correlated with height cubed. Respiratory system resistance progressively fell whereas volume-corrected flows remained fairly constant over the study period. These findings provide longitudinal lung function data and support the concept of isotropic lung growth.
在七名正常婴儿出生后的第一年，对其肺力学和部分用力呼气流量进行了连续测量。肺力学通过吸气末阻断技术测量，部分用力呼气流量通过快速胸部按压法测量。在功能残气量时测量的胸腔气体容积、顺应性和部分用力呼气流量随年龄逐渐增加，并与身高的立方相关。在研究期间，呼吸系统阻力逐渐下降，而经容积校正的流量保持相当恒定。这些发现提供了纵向肺功能数据，并支持各向同性肺生长的概念。
