At what age range is the normal respiratory rate between 14-22 breaths per minute?

The normal respiratory rate of 14-22 breaths per minute is characteristic of individuals aged 12 and older. This range reflects the typical respiratory patterns found in pre-teens, teenagers, and adults, who generally exhibit a lower respiratory rate than younger children, whose rates tend to be higher due to their smaller lung capacity and higher metabolic demands.

In contrast, younger age groups, such as children between the ages of 3-7, 5-10, or even pre-teens up to 12, usually have a higher respiratory rate, reflecting their developmental stage and physiological needs. Thus, the age range of 12 and up aligns perfectly with the specified normal respiratory rate, confirming that this rate is appropriate for a growing, more adult-like respiratory function.
