What is the typical respiratory rate for a healthy adult at rest?

The typical respiratory rate for a healthy adult at rest is 12 to 20 breaths per minute. This range is recognized as normal and reflects the body's need for oxygen and removal of carbon dioxide while at rest. Factors such as age, fitness level, and general health can influence the respiratory rate, but for a healthy adult, this range is established based on large population studies and clinical observations.

A respiratory rate lower than 12 breaths per minute could indicate bradypnea, while a rate higher than 20 breaths per minute could suggest tachypnea, both of which may require further evaluation to understand underlying health conditions. This normal range ensures adequate gas exchange and meets the metabolic demands of the body without overexertion, supporting overall respiratory health.
