Which tool besides age-based formula can be used to estimate pediatric airway size?

• A. Broselow tape
• B. Endotracheal sizing wheel
• C. Palpation
• D. Random guess

Answer: (A)

Estimating pediatric airway size works best when you use a child's length to gauge their overall size, not just age. The Broselow tape gives a quick length-based estimate of weight and then directly maps that weight to the appropriate endotracheal tube size and insertion depth. This approach accounts for variability in how children grow and body habitus, making it more reliable in real emergencies than age alone. It’s fast—you simply lay the tape alongside the child and read the color zone for the recommended tube size and depth. Palpation isn’t dependable for sizing, a sizing wheel isn’t a standard tool in this context, and guessing randomly can easily cause airway injury or misplacement.
