What is the term for the number of breaths taken per minute?

The term for the number of breaths taken per minute is called the respiratory rate. This measure is an important indicator of a person's respiratory health and overall physiological state. It reflects the frequency of breathing and is often assessed in both clinical and fitness settings to evaluate a person's response to exercise, stress, or various health conditions.

In contrast, tidal volume refers to the amount of air inhaled or exhaled in a single breath, while cardiac output pertains to the volume of blood the heart pumps per minute, a separate measure related to cardiovascular performance. Oxygen consumption, on the other hand, is a measure of how much oxygen is used by the body during metabolic processes, reflecting the efficiency of the body to utilize oxygen during physical activity. Each of these terms plays a distinct role in understanding different aspects of human physiology, but the specific term for breathing frequency is indeed the respiratory rate.
