At what age does the normal respiratory rate for children drop to 12-18 breaths/min?

The correct age at which the normal respiratory rate for children drops to 12-18 breaths per minute is typically from around 12 years and older. At this stage, children's respiratory systems have developed significantly, reflecting a rate similar to that of adults.

In younger age groups, such as infants and toddlers, respiratory rates are much higher due to their smaller lung capacity and faster metabolism. For example, in infants and toddlers (1-3 years), the respiratory rate can be much higher, typically in the range of 24-40 breaths per minute. As children grow, their respiratory rates gradually decrease, reaching lower ranges by the time they hit adolescence.

Understanding normal respiratory rates is crucial for caregivers, as it allows for effective monitoring of a child's respiratory health. Recognizing the expected rates for specific age groups can help in identifying potential health issues or abnormal respiratory patterns.
