What is the normal respiratory rate for an adult at rest?

The normal respiratory rate for an adult at rest typically ranges between 12 to 20 breaths per minute. Within this context, a rate of 15 breaths per minute is a representative figure that falls well within the standard range, making it a suitable answer.

This range reflects the body's need for oxygen and the efficiency of the respiratory system during periods of rest. Rates lower than 12 breaths per minute might indicate bradypnea, which could point to potential health issues, while rates exceeding 20 breaths per minute could indicate tachypnea, often related to stress, anxiety, or underlying medical conditions.

Therefore, the answer of 15 breaths per minute accurately aligns with what is considered normal for adults at rest and provides a practical understanding of typical respiratory function.
