  1. FVC%: forced vital capacity expressed in percent; FEV1%: forced expiratory volume in the 1 second expressed in percent; FEV1%/FVC: as just explained; COPD index: index of chronic obstructive pulmonary disease; MEF 50: mean expiratory flow at 50% vital capacity; MEF 25: mean expiratory flow at 25% vital capacity; ppo FEV1: predicted postoperative FEV1; pCO 2: partial pressure of CO2 in the arterial blood; pO 2: partial pressure of O2 in the arterial blood; DLCO: diffusing capacity for carbon monoxide; VO 2 max: maximal oxygen consumption.
