It is very difficult to manage the respiratory status of pediatric patients during anesthesia because children’s respiratory physiology changes dramatically from neonate to teenager. Anesthesiologists have to take particular care with each patient（age, body weight, height）to determine adequate ventilator setting according to idiosyncrasy. In addition, anesthesiologists have to understand the respiratory physiology of pediatric patients according to age：changes in respiratory rate, relatively narrow airway compared to adult patients, alveolar size and amount, stiffness of rib cage, etc. We select adequate tracheal tubes and set ventilator settings. It is also crucial to understand the difference in respiratory physiology between anesthetized mechanical ventilation and spontaneous breathing to manage pediatric patients.
