What is the normal respiratory rate range for adults?

The normal respiratory rate range for adults is 12 to 20 breaths per minute. This range is considered the standard for healthy adults at rest and reflects an adequate exchange of oxygen and carbon dioxide in the body. Rates below or above this range may indicate underlying health issues.

For instance, a rate lower than 12 breaths per minute could suggest bradypnea, which may be associated with conditions affecting the central nervous system or drug effects, while a rate over 20 breaths per minute could indicate tachypnea, often resulting from anxiety, fever, or respiratory distress. Understanding these parameters is essential in providing appropriate nursing care and interventions.
