What is the normal range for respiration rate in adults?

The normal range for respiration rate in adults is typically recognized as 12 to 20 breaths per minute. This range reflects the average number of breaths taken by a resting adult in a minute under normal circumstances. A rate within this range indicates that the body is adequately taking in oxygen and expelling carbon dioxide, supporting bodily functions efficiently.

When assessing respiration rates, healthcare professionals consider factors such as age, health status, and even physical activity. Rates lower than 12 may indicate bradypnea (slow breathing), while rates higher than 20 may suggest tachypnea (rapid breathing), which could be a response to various conditions such as anxiety, fever, or respiratory distress. Thus, option C accurately represents the standard range used in clinical settings for adult respiration rates.
