What is the average normal respiratory rate for infants?

• A. 50 breaths per minute
• B. 12-20 breaths per minute
• C. 30-60 breaths per minute
• D. 40 breaths per minute

Answer: (A)

Infants breathe much faster than older children and adults because their metabolic needs are higher and their lungs are smaller and still maturing. A normal resting rate for infants is about 30 to 60 breaths per minute. Within that range, 50 breaths per minute sits near the middle, making it a reasonable average to report. Other options fall outside the common midpoint: 12–20 is typical for adults, not infants; 30–60 is the broad normal range but doesn’t give a single representative average; 40 is within the range but 50 often serves as the standard mid-range value used in many clinical references. When measuring, count for a full minute and ensure the infant is at rest to get an accurate reading.
