| FEV1 – forced expiratory volume in the first second; FVC – forced vital capacity; SVC – slow vital capacity; PEF – peak expiratory flow; FEF25-75% – forced expiratory flow at 25 and 75% of the pulmonary volume; TLC – total lung capacity; RV – residual volume; FRC – functional residual capacity; DLCO – diffusing capacity of the lung for carbon monoxide; DLCO(Hb) – DLCO adjusted for hemoglobin; Kco – carbon monoxide transfer coefficient; Kco (Hb) – Kco adjusted for hemoglobin; Hb – hemoglobin. | |||
