At what age group is a respiratory rate of 12-20 breaths per minute typical?

A respiratory rate of 12-20 breaths per minute is typical for adults, as this range reflects the normal breathing pattern for this age group. In adults, the respiratory system is well-developed, allowing for efficient gas exchange, and the body requires a stable level of ventilation that falls within this range under resting conditions.

In contrast, the normal respiratory rates for other age groups differ significantly. For example, preschoolers tend to have a higher respiratory rate, typically ranging from 20-30 breaths per minute, reflecting their smaller lung capacities and higher metabolic rates. Similarly, school-age children and adolescents also exhibit respiratory rates that differ from adults, with school-age children averaging around 18-30 breaths per minute, and adolescents having rates that start to approach adult values but may still be slightly elevated compared to the adult norm. This is why the specified range correctly aligns with adults, making it vital for health professionals to understand these physiological differences across age groups when assessing respiratory health.
