WebAnother clue that an initial inspiration was inadequate comes from the position of the tidal loop within the maximal flow-volume loop. Over a relatively broad range of ages and heights the Expiratory Reserve Volume (ERV) is between one-third to one-quarter of the FVC (or alternately one-half to one-third the size of the Inspiratory Capacity (IC)). WebOct 27, 2011 · The Respiratory Flow Volume Loop (procedure code 94375) is used to evaluate the dynamics of both large and medium size airways. This test is more useful than the conventional spirogram. The procedure is the same for spirometry except for the addition of a maximal forced inspiration at the end of the force expiratory measures.
