1. How many breaths a minute is normal?

The frequency of normal breathing per minute is the breathing frequency, which refers to the frequency of breathing in a quiet state. This frequency is different in different age groups. The frequency of newborn babies is faster, and gradually slows down with the increase of age, but there is almost no difference between male and female babies. After testing, the respiratory rate of newborns can reach 40 beats/min, infants can reach 2030 beats/min, children can reach 20 beats/min, and adults can reach 10. The number of breaths of human body is mainly affected by oxygen demand, metabolites in the body, pathological or physiological changes and other factors. For example, when you have a fever, your metabolism will speed up and your breathing will speed up.

You can usually measure your breathing times. If there is something wrong with the number of breaths, you'd better go to the hospital for examination.
