WebTLC, a high IC and a low ERV. There was no evidence of gas trapping either absolute (high RV) or relative (high RV/TLC); in fact, FRC and RV were low. The V A, as determined by methane dilution in the single-breath TLCO measurement [7], was normal-to-low in tandem with TLC, i.e. the V A/TLC ratio was within normal limits (0.8) [8–10]. WebRestriction was defined as total lung capacity (TLC) less than 80% predicted, and gas trapping on plethysmography was defined as a residual volume (RV) to TLC ratio (RV/TLC) of greater than 45%. A low DLco (corrected for hemoglobin) and DLco with alveolar volume (VA) correction (ie, DLco/VA) were defined as values of less than 80% predicted.
