What is the normal adult range for respirations per minute?

• A. 8-12 breaths/minute
• B. 12-20 breaths/minute
• C. 20-30 breaths/minute
• D. 30-40 breaths/minute

Answer: (B)

The normal adult range for respirations per minute is 12-20 breaths. This range is considered to be the typical rate at which an adult breathes when at rest. Respirations in this range indicate stable and efficient respiratory function, allowing for effective gas exchange in the lungs.

Breathing rates outside this range can indicate various physiological conditions. For instance, rates below 12 breaths per minute can be seen in individuals who may be experiencing respiratory depression, while rates exceeding 20 breaths per minute can indicate conditions such as anxiety, pain, or respiratory distress. Understanding this normal range is crucial for monitoring respiratory health and identifying potential medical concerns.
