| Objective:Peak Expiratory Flow(PEF)is an important screening method for investigation and follow-up of pulmonary function,since reading the obtained PEF results requires reference values,the aim of this study was to establish normal values of Peak Expiratory Flow(PEF)for our children population in XinJiang.Material and Method:We investigated 3520 healthy children(1705 males and 1815 females)aged from 7 to 16 years.Using MicroPeak Peak Flow Meter(PFM),We measured the PEF values and wrote down children's age,sex,height and weight in both sexes.The statistical solflware SPSS14.0 was used to fit the model.Result:With the increasing of the height, age and weight PEF is increasing.Height,age and weight were found to correlate significantly with peak expiratory flow in both sexes.Conclusion:Regression equations for sex and height were made after measurement and data analysis.PEF values can be easily calculated knowing one's height. |
