Design outcomes

Primary

Measure	Time frame
Ventilatory parameters (peak airway pressure, plateau pressure, mean airway pressure, inspiratory and expiratory tidal volume, inspiratory and expiratory minute ventilation, inspiratory expiratory ratio, compliance, airway resistance,end tidal carbon dioxide)Timepoint: After intubation/Supraglottic airway device placement, before carboperitoneum, after carboperitoneum, at 10 minutes after position, after release of carboperitoneum.	—
