What is the normal respiratory rate for an adult?

The normal respiratory rate for an adult typically ranges from 12 to 18 breaths per minute. This range reflects the average number of breaths taken when a person is at rest and not exerting themselves physically. Maintaining a respiratory rate within this range is important for adequate gas exchange in the lungs, ensuring that there is a sufficient intake of oxygen and a proper expulsion of carbon dioxide.

Understanding normal respiratory rates can be crucial in clinical settings, as deviations could indicate various health issues. For example, a rate below the normal range may signify bradypnea, while a rate above it may suggest tachypnea, both of which could warrant further assessment. The provided range of 12 to 18 breaths per minute captures this normal physiological state well.
