Table 6. Pulmonary function tests in patients with sarcoidosis.
| Pulmonary function tests | n (%) |
| FEV1 (n=99) | |
| ≥80% predicted | 56 (56.6) |
| <80% predicted | 43 (43.4) |
| FVC (n=99) | |
| ≥80% predicted | 73 (73.7) |
| <80% predicted | 26 (26.3) |
| FEV1/FVC (n=99)* | |
| 75 - 82 | 34 (34.3) |
| <70 | 21 (21.2)† |
| TLC (n=78) | |
| ≥80% predicted | 66 (84.6) |
| <80% predicted | 12 (15.4) |
| DLCO (n=78) | |
| <80% predicted | 29 (37.2) |
FEV1 = forced expiratory volume in 1 second
FVC = forced vital capacity
TLC = total lung capacity
DLCO = diffusion capacity for carbon monoxide
* 75 - 82 considered normal
† 16 patients had a normal FVC and 5 a reduced FVC
