目的建立成都地区正常儿童简易呼气峰流速值的参考值。方法以成都地区450名健康儿童为研究对象,采用美国伟康公司生产的580型呼气峰值流速测试仪测定呼气峰流速(PEF),分析其影响因素,采用SPSS14.0进行统计分析。结果男女儿童PEF与身高、年龄、体重均有密切关系,与身高关系最密切,体重对其影响最小。并且随身高、年龄的增加而增长。结论分别建立了男女儿童PEF与身高的直线回归方程。
Objective To establish a reference value of simple expiratory peak flow velocity of normal children in Chengdu. Methods A total of 450 healthy children in Chengdu were enrolled in this study. Peak expiratory flow (PEF) was measured by the 580-type expiratory peak flow tester manufactured by Weike company. The influencing factors were analyzed and analyzed by SPSS14.0. Results The PEF of boys and girls was closely related to height, age and weight, most closely related to height, and weight had the least effect on PEF. And with height, age and growth. Conclusions The linear regression equation between PEF and height of boys and girls respectively was established.
