What is the normal respiratory rate for an 18-month-old male child?

The normal respiratory rate for an 18-month-old child typically falls within the range of 30 to 40 breaths per minute. This range is established based on pediatric guidelines, which indicate that as children grow, their respiratory rates gradually decrease. Infants have a higher respiratory rate compared to older children and adults, but by the time a child reaches 18 months, their rate stabilizes to this specific range. Understanding these normal vital sign parameters is crucial in pediatric assessment, as deviations can indicate respiratory distress or other clinical concerns.

In this context, options reflecting significantly lower or higher respiratory rates do not align with the expected norms for this age group. Accurate knowledge of vital sign benchmarks is essential for effective monitoring and intervention in pediatric care.
