Pediatric airway management is characterized by which true statement?

• A. Airways are proportionally smaller than adults
• B. Larger airways in proportion to adult patients
• C. Higher metabolic requirement
• D. Decreased Functional Residual Capacity

Answer: (A)

The key idea here is that pediatric airways are proportionally smaller than adult airways, and that size difference has a major impact on how you manage ventilation and intubation. Because the radius of a tube or airway is drastically smaller in children, even a tiny decrease in diameter from swelling, secretions, or an endotracheal tube can cause a large jump in airway resistance. This makes obstruction more likely and ventilation more difficult, so sizing devices carefully, choosing appropriate equipment, and using gentle technique are critical. The small airway diameter also means children desaturate more quickly during apnea, so rapid preoxygenation and efficient airway management are vital.

While children do have higher oxygen consumption per kilogram and a lower functional residual capacity, which contribute to rapid desaturation, the most defining factor that shapes airway management decisions is the proportionally smaller airway size.
