Final answer:
The average number of breaths per minute in slow-paced breathing is around 6 breaths per minute, which is less than the average non-exertion rate of 12-15 breaths per minute.
Step-by-step explanation:
The average number of breaths per minute when using slow-paced breathing is typically around 6 breaths per minute. This is a significant reduction from the average respiratory rate under non-exertion conditions, which is about 12-15 breaths per minute. Slow-paced breathing involves taking fewer breaths per minute while increasing the tidal volume per breath (the amount of air inhaled or exhaled), which helps maintain adequate alveolar ventilation and prevents carbon dioxide buildup in the alveoli.
