| Parameter | Measured | Predicted value | Lower limit | % predicted |
| FEV1 (L) | 1.00 | 3.54 | 2.84 | 28 |
| FEV1/FVC | 62.25 | 84.35 | 73.64 | 74 |
| FVC (L) | 1.60 | 4.11 | 3.28 | 39 |
| TLC (L) | 3.61 | 5.30 | 4.31 | 68 |
| DLCO (mL·min−1·mmHg−1) | 11.14 | 23.97 | 18.65 | 46 |
| DLCO/VA (mL·min−1·mmHg−1·L−1) | 4.52 | 4.69 | 3.66 | 96 |
FEV1: forced expiratory in 1 s; FVC: forced vital capacity; TLC: total lung capacity; DLCO: diffusing capacity of the lung for carbon monoxide; VA: alveolar volume.
