PEAK EXPIRATORY FLOW RATE - NORMAL VALUES
For use with EU/EN13826 scale PEF meters only
Adapted by Clement Clarke for use with EN13826 / EU scale peak flow meters
from Nunn AJ Gregg I, Br Med J 1989:298;1068-70
In men, readings up to 100 L/min lower than predicted are
within normal limits. For women, the equivalent figure is 85
L/min. Values are derived from Caucasian populations.

Clement Clarke has developed mathematical equations that
will allow conversion of P.E.F. readings from Wright-
McKerrow scale to EN 13826 scale, and vice-versa. Contact
