   The volume of air remaining in the lung at the end of spontaneous expiration (i.e. end-expiratory lung volume (EELV)) is increased in COPD compared with health. EELV is synonymous with the more conventional term “functional residual capacity”.

   9 lut 2017 · Four standard lung volumes, namely, tidal (TV), inspiratory reserve (IRV), expiratory reserve (ERV), and residual volumes (RV) are described in the literature. Alternatively, the standard lung capacities are inspiratory (IC), functional residual (FRC), vital (VC) and total lung capacities (TLC).
