R refers to respiratory rate in medicine, which means the number of breaths per minute. It is one of the important indicators reflecting the functional status of the respiratory system. The normal range varies with age, as detailed below:
1. Newborns (0–1 month): 30–60 breaths per minute
2. Infants (1–12 months): 20–30 breaths per minute
3. Toddlers (1–3 years): 20–30 breaths per minute
4. Preschool children (3–6 years): 18–25 breaths per minute
5. School-aged children (6–12 years): 15–20 breaths per minute
6. Adolescents (12–18 years): 12–20 breaths per minute
7. Adults (18 years and older): 12–20 breaths per minute
It should be noted that the normal range for respiratory rate is not absolute and may be influenced by various factors, such as physical activity, emotional excitement, and changes in temperature. If you notice that your own or someone else's respiratory rate is clearly outside the normal range, medical evaluation should be sought promptly, followed by appropriate treatment based on the specific condition.
