The normal number of breaths per minute for a healthy adult at rest typically ranges from 12 to 20 breaths per minute. Some sources specify a narrower range of 12 to 16 breaths per minute, while others note 12 to 18 or up to 20 as normal
. This respiratory rate reflects the balance needed for adequate oxygen intake and carbon dioxide removal under resting conditions. Variations within this range can depend on factors such as age, physical fitness, health status, and whether the person is at rest or active. For example, elderly adults may have a slightly wider normal range, and children have higher normal respiratory rates that decrease with age
. In summary:
- Typical adult resting respiratory rate: 12–20 breaths per minute
- Common narrower range cited: 12–16 breaths per minute
- Elderly adults: may range from about 12 to 28 breaths per minute
- Children: higher than adults, decreasing with age
Respiratory rate is a vital sign used to assess respiratory and overall health, with deviations from the normal range potentially indicating medical issues that may require evaluation
