This observational study aims to evaluate the effects of different inspiratory to expiratory (I:E) ratios (1:2 vs. 1:3) during mechanical ventilation in pediatric patients undergoing dental procedures under general anesthesia. Due to behavioral challenges, dental phobia, or medical conditions, general anesthesia is often required to ensure immobility and cooperation during dental treatments in children. In the clinic where the study will be conducted, the I:E ratio is routinely adjusted approximately 20-30 minutes before the end of the procedure to facilitate a smoother transition to spontaneous breathing during emergence from anesthesia. While 1:2 is commonly used, the 1:3 ratio may improve respiratory efficiency and recovery by prolonging the expiratory phase. The study aims to compare vital signs, respiratory parameters (heart rate, blood pressure, SpOâ‚‚, EtCOâ‚‚, respiratory rate), recovery quality, and respiratory complications between the two I:E ratios. The findings aim to optimize ventilation strategies and improve patient comfort and safety during emergence from anesthesia.
