Breathing rate, also known as respiratory rate, refers to the number of breaths a person takes per minute. It is an important indicator of a person's respiratory health and can vary depending on factors such as age, physical activity, health status, and environmental conditions.

Typically, the normal breathing rate for an adult at rest is between 12 and 20 breaths per minute. In children, the rate may be higher. An abnormal breathing rate, either too fast (tachypnea) or too slow (bradypnea), can be a sign of underlying medical conditions.
