What is the average respiratory rate (RR) for a resting adult?

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

Answer: (B)

The average respiratory rate for a resting adult typically falls between 12 to 20 breaths per minute. This range is considered normal and reflects a healthy functioning respiratory system at rest. Within this range, individual variability can occur due to factors such as fitness level, age, and even the presence of respiratory illness. A personal resting respiratory rate within this range suggests efficient gas exchange and overall good pulmonary function. Breathing rates slower than 12 breaths per minute may indicate bradypnea, which could be associated with various conditions such as respiratory depression or increased intracranial pressure. Conversely, a respiratory rate exceeding 20 breaths per minute may indicate tachypnea, often seen in states of anxiety, fever, or respiratory distress. Thus, option B accurately represents the normal physiological range for adult respiration while understanding that deviations from this range can signify underlying health issues.
