  • FEV1: forced expiratory volume in 1 s; FVC: forced vital capacity; VC: vital capacity; TLC: total lung capacity; FRC functional residual capacity; RV: residual volume; TL,CO: transfer factor of the lung for CO; KCO: transfer coefficient of the lung for CO. Spirometry showed some mild small airways obstruction, but her lung function was essentially normal.
