What is the normal respiratory rate range for adults?

The normal respiratory rate range for adults is typically defined as 12 to 20 breaths per minute. This range indicates the average number of breaths a healthy adult should take while at rest. Factors such as age, health conditions, and physical fitness can slightly influence an individual’s respiratory rate, but the standard range provides a baseline for assessing respiratory health.

The option that lists 10 to 20 breaths per minute includes values that are lower than what is commonly accepted for adult respiratory rates. A respiratory rate consistently below 12 breaths may be indicative of respiratory distress or other medical concerns. This is why understanding the correct range is important for proper health assessment and response.
