Fig 2. Within-subject difference in FRC measured by multiple breath nitrogen washout (FRCN2) and body plethysmography (FRCpleth).

Fig 2

The mean within-subject difference FRCN2—FRCpleth decreased after the three tissue N2 excretion equations were applied to washout data from healthy and CF populations.
