- In children (especially infants), the sensitivity of the respiratory system (narrow and collapsible airways), circulatory system (weak myocardial contractility), and nervous system (immature blood brain barrier) to anesthetic agents is 2-3 times higher than in adults.
- In children, oxygen consumption is 200% of that in adults, while functional residual capacity is only 50%, resulting in an apnea tolerance time of less than 2 minutes.
- In children, the risk of intraoperative oxygen desaturation is 4 times higher than in adults, necessitating a life support system with second-level response capability.
