Basic characteristics of chronic obstructive pulmonary disease subjects
| Smoking history (pack-yrs) | FEV1/FVC % | RV L | TLC L | RV/TLC % | DL,CO mL·min−1·mmHg−1 | % DL,CO |
| 102.2±40.4 | 44.3±12.7 | 2.56±0.11 | 5.67±0.89 | 45.5±9.2 | 11.0±3.4 | 49.2±14.0 |
Data are presented as mean±SEM
FEV1: forced expratory volume in one second
FVC: forced vital capacity
RV: residual volume
TLC: total lung capacity
DL,CO: diffusing capacity of the lung for carbon monoxide. (mmHg×0.133=kPa)
