Which age group typically has a respiratory rate of 22-34 breaths/min?

The age group that typically has a respiratory rate of 22-34 breaths per minute is preschool children. During this developmental stage, which ranges roughly from ages 3 to 5 years, children experience a variety of physiological changes, and their respiratory rate tends to normalize within this range due to factors such as increased lung capacity and efficiency in gas exchange as they grow.

In contrast, infants have a considerably higher respiratory rate, often ranging from 30-60 breaths per minute, as they are in a rapid growth phase and their metabolic demands are high. Toddlers, aged 1-3 years, also experience a higher respiratory rate than preschool children, usually around 24-40 breaths per minute. School-age children, typically aged 6 years and older, tend to have respiratory rates that decrease further, usually ranging from 18-30 breaths per minute. Thus, the respiratory rate of preschool children distinguishes them from the other age groups.
