Table 2
Mean (SD) lung volumes and C5 responses of normal subjects, both strapped and unstrapped, compared with patients with CFA
| Unstrapped (n=9) | Strapped (n=9) | CFA (n=15) | |
|---|---|---|---|
| FVC % predicted | 111 (14) | 63 (14) | 75 (14) |
| FEV1 % predicted | 123 (15) | 71 (15) | 82 (11) |
| RV % predicted | 100 (24) | 75 (30) | 75 (30) |
| TLC % predicted | 101 (16) | 67 (15) | 74 (16) |
| FRC (l) | 3.2 (1.0) | 2.2 (0.8) | 2.5 (0.9) |
| IC (l) | 3.5 (0.8) | 2.0 (0.6) | 1.9 (0.4) |
-
FVC = forced vital capacity; FEV1 = forced expiratory volume in one second; RV = residual volume; TLC = total lung capacity; FRC = functional residual capacity; IC = inspiratory capacity.
