What is the normal respiratory rate range for adults?

The normal respiratory rate range for adults is considered to be between 12 to 20 breaths per minute. This range reflects the typical resting respiratory rate for healthy adults and indicates a balance of oxygen intake and carbon dioxide expulsion that is necessary for maintaining adequate metabolic functioning.

A respiratory rate below or above this range may indicate underlying health issues or physiological stress. Rates below 12 can suggest bradypnea, which may be seen in conditions like respiratory depression or certain neurologic issues. Conversely, a rate exceeding 20 may indicate tachypnea, often associated with factors like exercise, anxiety, fever, or respiratory illness. Understanding this normal range is vital for healthcare professionals as it aids in assessing a patient's respiratory status and overall health.
