The aim of this study is to assess the impact on lung mechanics during robotic lung resection when no capnothorax is used.
Assess the improvement of oxygenation, ventilation and lung mechanics in patients ventilated with individualized PEEP without capnothorax. PEEP requirement and lung mechanics without capnothorax will be compared with a historical cohort population of robotic surgery with capnothorax.

| Measure | Description | Time Frame |
|---|---|---|
| Respiratory airway pressures | Respiratory airway pressures (peak pressure, plateau pressure and PEEP in cmH2O) | During intra-operative mechanical ventilation (4 hours) |
| Respiratory rate | Respiratory rate (in cycles per minute) | During intra-operative mechanical ventilation (4 hours) |

| Measure | Description | Time Frame |
|---|---|---|
| Arterial blood gas parameters: pO2 | pO2 in mmHg in arterial blood gas sample | During intra-operative mechanical ventilation (4 hours) |
| Arterial blood gas parameters: pCO2 | pCO2 in mmHg in arterial blood gas sample |
