Absolute % pred
FVC L 2.37 ± 0.7 71.66 ± 17.24
FEV1 L 1.95 ± 0.5 78.51 ± 18.13
FEV1/FVC % pred 83.5 ± 0.05
TLC L 3.94 ± 1.1 71.91 ± 15
DL,CO mL·min−1·mmHg−1 13.37 ± 0.51 57.89 ± 1.78
KCO mL·min−1·mmHg−1·L−1 3.73 ± 0.1 79.86 ± 2.36
Pa,O2 mmHg 75.09 ± 0.14

Data are presented as mean ±sd. % pred: % predicted; FVC: forced vital capacity; FEV1: forced expiratory volume in one second; TLC: total lung capacity; DL,CO: diffusion capacity of the lung for carbon monoxide; KCO: ratio between DL,CO and alveolar volume; Pa,O2: arterial oxygen tension; PA–a,O2: alveolar–arterial oxygen tension difference. 1 mmHg=0.133 kPa.
