What is the normal range for adult respiratory rate?

The normal range for an adult's respiratory rate is classified as 12 to 20 breaths per minute. This range reflects the typical respiratory rhythm that can be observed in healthy adults at rest. Breathing rates can vary based on several factors, including age, activity level, and overall health, but generally, when examining a resting adult, a rate within 12 to 20 breaths indicates adequate ventilation and normal function of the respiratory system.

A respiratory rate lower than 12 breaths per minute may suggest bradypnea, which can be associated with various medical conditions, whereas a rate exceeding 20 breaths per minute indicates tachypnea, which might reflect a response to stress, anxiety, or underlying health problems. Understanding the normal respiratory range is crucial for healthcare providers in assessing a patient’s respiratory function and overall physiological state.
