What is the normal adult respiratory rate?

• A. 10 to 15 breaths per minute
• B. 12 to 20 breaths per minute
• C. 16 to 24 breaths per minute
• D. 20 to 30 breaths per minute

Answer: (B)

The normal adult respiratory rate is typically considered to be between 12 to 20 breaths per minute. This range represents the average respiratory function for a healthy adult at rest, allowing for sufficient oxygen exchange without inhalation or exhalation occurring too rapidly or too slowly. Understanding that respiratory rates can vary based on factors such as age, fitness level, and overall health is important, but the established norm for adults is grounded in physiological research and clinical practice. Rates below or above this normal range can indicate possible respiratory problems or other health issues. Thus, the choice of 12 to 20 breaths per minute as the correct answer aligns accurately with the clinical criteria used worldwide for assessing respiratory function in adults.
