In the intervention group after induction of anesthesia & intubation, patients will be ventilated with pressure control mode. so the pressure will increase until ideal tidal volume (6-8 ml/kg) reached
In control group for mechanical ventilation during anesthesia, volume control mode will be used. Tidal volume set on 6-8 ml/kg of ideal body weight.
