The time of inspiration was unchanged whilst the time of deadspace washout was reduced by 16%. After bronchodilatation the absence of a change in TI' was due to the overestimation of effective breathholding time being offset by an increase in the proportion of alveolar volume measured by the single-breath procedure.(ABSTRACT TRUNCATED AT 250 WORDS) ER -
