[The maximary expiratory flow-volume curve].
The maximal expiratory flow-volume curve is obtained by recording simultaneously, in the course of a forced expiration, the volume in abscissa and the flow in ordinate. Mention is made of the various recording technics and also of the ways for quantifying the results (determinations of the instantaneous flows at various volumes). The clinical applications of the flow-volume curves are taken in consideration. The advantages and inconvenients of this method are discussed.
