Table 1
Comparisons of the lung function parameters and 6-minute-walking test before and after endoscopic lung volume reduction.
| Lung function parameter | Before application of AeriSeal | 12 weeks after application of AeriSeal |
| Peripheral oxygen saturation with 2 L supply | 93% | 98% | Oxygen partial pressure | 58 mmHg | 89 mmHg | FEV 1 L (% pred) | 1.3 (37) | 1.4 (44) | Forced vital capacity (FVC) L (% pred) | 3.2 (76) | 3.2 (76) | TLCOc SB mmol/min/kPa
| 21% | 25% | TLCOc/VA mmol/min/kPa | 24% | 28% | Total lung capacity (TLC) L (% pred) | 7.9 (122%) | 7.6 (117%)
| Residual volume L (% pred) | 4.7 (216) | 4.5 (202) | SR tot (kPa·s) (% pred) | 2.6 (217) | 1.79 (151) | 6-minute-walking test (m) | 150 | 230 |
