| Mean | 50 | 74 | 55 | 132 | 105 | 39 | 34 | 5.07 | 10.53 |
| Standard deviation | 25 | 26 | 24 | 33 | 31 | 7.8 | 19 | 0.64 | 2.0 |
FEV1 = forced expiratory volume in one second; FVC = forced vital capacity; RV = residual volume; TLC = total lung capacity; Tlco = carbon monoxide lung transfer factor; Paco 2, Pao 2 = arterial carbon dioxide and oxygen tension.
