End-Expiratory Lung Volume in Children Awakening From Propofol Anesthesia

Overview

The goal of this pilot randomized clinical trial is to test the effects of high flow nasal oxygen and head elevation during awakening from propofol anesthesia in pediatric patients undergoing airway surgery. The main question\[s\] it aims to answer are: * High flow oxygen can decrease the occurence of atelectasis during awakening from propofol anesthesia in pediatric patients? * Head elevation can decrease the occurence of atelectasis during awakening from propofol anesthesia in pediatric patients? Researchers will compare high flow oxygen vs low flow oxygen group to see if the use of high flow oxygen decrease the occurence of atelectasis during awakening from propofol anesthesia. And in each group, the patients will be assigned to supine position vs head elevation position to compare the effects of head elevation during awakening from propofol anesthesia.
