two parameters , the ratio of forced maximal expiratory flow ( measured from the maximal partial fefv curve ) to tidal expiratory flow ( measured from the expiratory flow-volume curve of tidal breathing ) at midtidal volume ( vm1d ( forced/tidal ] and the minimal compression pressure required to generate maximal expiratory flow at frc ( pmin ) , satisfactorily quantified respiratory function without the need for size correction with absolute lung volume .
