Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Volume controlled ventilation
During the steep trendelenburg position and pneumoperitoneum, volume controlled ventilation will be applied with 8ml/kg (ideal body weight) and inspiration:expiration ratio (I:E) = 1:2.
Volume controlled ventilation
During anesthesia and surgical procedure, volume-controlled ventilation will be applied with an inspiration:expiration ratio of 1:2 and a tidal volume of 8 mL per ideal body weight (kg) without ventilatory mode change.
Autoflow-volume controlled ventilation
During the steep trendelenburg position and pneumoperitoneum, Autoflow-volume controlled ventilation will be applied with 8ml/kg (ideal body weight) and inspiration:expiration ratio (I:E) = 1:2.
Autoflow-volume controlled ventilation
After tracheal intubation, volume-controlled ventilation will be initiated with an I:E ratio of 1:2 and a tidal volume of 8 mL per ideal body weight (kg). Immediately after CO2 pneumoperitoneum with steep Trendelenburg positioning, Autoflow-volume controlled ventilation will be applied instead of volume-controlled ventilation. Immediately after CO2 desufflation and supine positioning, volume-controlled ventilation will be applied again.
