Abstract
A new lung function index, the area under the maximum expiratory flow-volume curve (AFVx) is described. A predicted AFVx based on age, sex and height is determined, and the measured to predicted AFVx ratio is assessed by comparison with other established lung function parameters. This ratio appears to be a very sensitive indicator of the degree of lung function impairment.
