Peak Expiratory Flow RateNormal Values

In men, readings up to 100 L/min lower than predicted arewithin normal limits. For women, the equivalent figure is 85 L/min.

Values are derived from Caucasian populations.

Normal PEF values in children correlate best with height; with increasing age, larger differences occur between the sexes.

These predicted values are based on the formulae given inLung Function by J.E. Cotes (Sixth Edition),

adapted for Mini-Wright peak flow meters by Clement Clarke.
