Estimated/Expected Peak Expiratory Flow (Peak Flow)

Gender
Age
Height inches
Estimated Peak Flow: L/min
Note: There are many different equations and models for estimating peak flow. While results are frequently similar, they are not exactly the same.

Children: PEFR = ((Height in cm - 100) * 5) + 100
Adult Men: ((Height * 5.48) + 1.58) - (Age * 0.041)) * 60
Adult Women: (((Height * 3.72) + 2.24) - (Age * 0.03)) * 60
