Average Normal Values for the Forced Expiratory Volume in White Caucasian Males

Abstract

A linear regression of forced expiratory volume (F.E.V.1) on age and height is reported for 275 healthy male subjects living in the United Kingdom. The regression coefficients are similar to those reported from other countries in N.W. Europe and N. America. The equations have therefore been combined to yield the following overall relationship, which may be of use for predicting average normal values: F.E.V.1= 3.62 Ht (m.) - 0.031 age (years) - 1.41 (S.D.>0.5) 1 B.T.P.S. The limitations to the use of this relationship are discussed. © 1966, British Medical Journal Publishing Group. All rights reserved.
