Table 2. Acceptance and exclusion criteria after 4–6 h of ex vivo lung perfusion.
| Acceptance criteria |
| Delta pO2 ≥350 mmHg |
| Stable or improving pulmonary artery pressure |
| Stable or improving airway pressures |
| Stable or improving pulmonary compliance |
| Acceptable STEEN solution loss |
| Exclusion criteria |
| Delta pO2 <350 mmHg |
