What is the normal adult respiratory rate?

The normal adult respiratory rate is 12 to 20 breaths per minute. This range is considered the standard for healthy adults at rest and reflects a normal level of respiratory function. Understanding this range is important for assessing a patient’s respiratory status, as deviations can indicate underlying health issues.

A rate lower than 12 breaths per minute can indicate bradypnea, often associated with conditions such as respiratory depression, neurological disorders, or drug overdoses. Conversely, a rate higher than 20 breaths per minute may suggest tachypnea, which could be the result of anxiety, fever, pain, or underlying respiratory or cardiovascular conditions.

Recognizing the normal respiratory rate allows healthcare providers to identify abnormalities and initiate further assessment or interventions as needed.
