What is the normal respiratory rate for an adult?

The normal respiratory rate for an adult typically falls within the range of 12 to 20 breaths per minute. This range is considered standard physiological functioning for a resting adult, indicating adequate ventilation and oxygen exchange in the body.

A respiratory rate below 12 breaths per minute is generally categorized as bradypnea, which can signal underlying health issues, particularly in cases of respiratory depression. Conversely, a rate exceeding 20 breaths per minute can be classified as tachypnea, often associated with heightened physical activity, anxiety, or respiratory distress.

Understanding these parameters is crucial for healthcare professionals in assessing a patient's respiratory status and overall health. Recognizing what constitutes normal respiratory rates can enhance clinical judgment and facilitate timely intervention when respiratory abnormalities are detected.
