从代表亚利桑那州图森市白人群体的随机选择群体中，获得了 3,115 人的满意的流量数据。来自 746 名完全没有心肺疾病症状或病史且从未吸烟的受试者的数据被用于确定肺量参数和最大呼气流量的“正常”预测方程。最大呼气流量-容量曲线显示出相当大的受试者间差异，但当排除疾病、侮辱或损伤的影响时，随着年龄的增长，平均最大呼气流量-容量曲线的形状几乎没有变化。
From a randomly selected population representative of the white population of Tucson, Ariz., satisfactory flow-volume data were obtained for 3,115 persons. Data from the 746 subjects who were totally free of symptoms or history of cardiorespiratory disease and who had never smoked were used in determining "normal" prediction equations for spirometric parameters and maximal expiratory flows. The maximal expiratory flow-volume curve showed considerable intersubject variability, but little change in shape of the mean maximal expiratory flow-volume curve was seen with advancing age when the effects of disease, insult, or injury were excluded.
