What is the normal range for adult respiratory rate?

• A. 10 to 15 breaths per minute
• B. 12 to 20 breaths per minute
• C. 15 to 25 breaths per minute
• D. 20 to 30 breaths per minute

Answer: (B)

The normal range for adult respiratory rate is 12 to 20 breaths per minute. This range is considered to be the standard baseline for assessing respiratory function in adults at rest.

When you take a person's respiratory rate, you are measuring how many times they inhale and exhale within a minute. Rates below 12 breaths per minute can indicate bradypnea, while rates above 20 breaths per minute can point to tachypnea. Both conditions may suggest underlying health issues that need to be evaluated.

Understanding this range is crucial for emergency medical technicians as respiratory rate is a vital sign that can indicate a patient’s respiratory status and overall health. Any deviations from this normal range warrant further assessment and potential interventions.
