Manual Ventilation Versus Pressure Controlled Mechanical Ventilation in Children

Comparison Between Pressure Controlled Mechanical Ventilation and Manual Ventilation During Mask Ventilation for Induction of Anesthesia in Children

The investigator will compare the feasibility of manual ventilation and pressure-controlled mechanical ventilation during facemask ventilation in children. The hypothesis is that the incidence of gastric insufflation would be lower during pressure-controlled mechanical ventilation when compared to manual ventilation.
