Volume-Controlled Ventilation and Pressure-Controlled Ventilation Volume Guaranteed in Obese Patients in Laparoscopic-Assisted Surgery

"Respiratory parameters will be set as: actual tidal volume 8 mL/kg actual body weight, respiratory rate 12 breaths/min, PEEP of five mmHg, oxygen flow 1 L/min, fraction inspired oxygen (FiO2) 0.6, and I:E ratio of 1:2.~Respiratory parameters will be kept constant if ETCO2 is \<45 mmHg. When ETCO2 exceed 45 mmHg, respiratory rate or tidal volume will be adjusted to maintain ETCO2 below 45 mmHg."
