Tidal volume (TV): Air inhaled and exhaled during quiet breathing

  1. Inspiratory reserve volume (IRV): Maximum volume of air that can be inspired in excess of normal inspiration

  2. Expiratory reserve volume (ERV): Maximum volume of air that can be expired in excess of normal expiration

  3. Residual volume (RV): Volume remaining after maximal expiration

Lung capacities

  1. Inspiratory capacity (IC) = TV + IRV

  2. Vital capacity (VC) = TV + IRV + ERV or IC + ERV

  3. Functional Residual Capacity (FRC) = ERV + RV

  4. Total lung capacity (TLC) = IRV + TV + ERV +
