SPIROMETRIC STUDIES OF VENTILATORY CAPACITY IN ELDERLY PEOPLE

Abstract
Dynamic lung function tests have been studied in apparently healthy men and women, who in essential respects may be considered as representative of the total population within the age range concerned. The results are compared with some previously reported “normal values”. Certain not unimportant differences exist in spite of essentially identical methods. It seems probable that these differences are due mainly to differences in the composition of the series compared; in previous investigations the selection of subjects does not appear to have been done on an adequate statistical basis.
