Peak expiratory flow (PEF) is an important screening method for investigation and follow-up of the pulmonary function. Since reading the obtained PEF results requires reference values, the aim of this study was to establish normal values for PEF in our adolescent population.
The investigation included 1154 healthy teenagers aged from 15 to 19 years using a peak flow meter Harlow, Essex CM 2ED. Detailed explanations, purpose of investigation and function demonstrations were done prior to testing. Results were statistically analyzed.
Obtained results showed an increase of PEF values with age and body height in both sexes. Elevation of PEF was more significant in boys; high correlation was found in regard to age and height in boys and moderate correlation in girls.
Regression equations for sex, age and height were made after measurements and data analysis. PEF values can be easily calculated knowing one's age and height.
呼气峰值流速（PEF）是用于调查和跟踪肺功能的一种重要筛查方法。由于读取获得的PEF结果需要参考值，本研究的目的是建立我们青少年人群的PEF正常值。
使用埃塞克斯郡哈洛CM 2ED型峰值流量计对1154名年龄在15至19岁的健康青少年进行了调查。在测试前进行了详细的解释、调查目的和功能演示。对结果进行了统计分析。
获得的结果显示，男女两性的PEF值均随年龄和身高增加。男孩的PEF升高更为显著；男孩的年龄和身高之间存在高度相关性，女孩则为中度相关性。
在测量和数据分析后得出了性别、年龄和身高的回归方程。知道一个人的年龄和身高就可以很容易地计算出PEF值。
