What is the normal respiratory rate range for a healthy adult?

The normal respiratory rate for a healthy adult is typically between 12 and 20 breaths per minute. This range reflects the average resting rate for adults, where ventilation is sufficient to meet the metabolic needs of the body without causing undue strain. When assessing respiratory rates, it's important to take into account factors such as the individual's level of exertion, age, and overall health status, but within a resting state, 12-20 breaths/min provides a reliable indication of normal respiratory function. A respiratory rate outside this range could suggest various conditions, such as respiratory distress or metabolic imbalances.
