To determine the relation of functional residual capacity and maximal expiratory flow at functional residual capacity to sex, age, height, and weight in healthy young children living in Portland, Oregon, we tested 37 boys and 36 girls using a modified helium-dilution technique and partial expiratory flow-volume curves. Within the age, height, and weight ranges studied, exponential or multiple regression techniques offered no substantial advantage over simple linear regression using height, weight, or age. There were no sex differences for the relationship between either variable and age, height, or weight. These techniques can readily be used in children as young as 3 years of age and may provide a method for studying lung growth and development in early childhood and a way to observe the progression of disease or the effect of treatment in the young child.
为了确定俄勒冈州波特兰市健康幼儿的功能残气量以及功能残气量时的最大呼气流量与性别、年龄、身高和体重之间的关系，我们使用改良的氦稀释技术和部分呼气流量-容积曲线对37名男孩和36名女孩进行了测试。在所研究的年龄、身高和体重范围内，指数回归或多元回归技术与使用身高、体重或年龄的简单线性回归相比没有显著优势。在这两个变量与年龄、身高或体重之间的关系上没有性别差异。这些技术可以很容易地应用于年仅3岁的儿童，可能为研究幼儿期肺的生长发育提供一种方法，以及观察幼儿疾病进展或治疗效果的一种方式。
