What is the normal respiratory rate in adults?

The normal respiratory rate for adults is considered to be between 12 and 20 breaths per minute. This range signifies a healthy respiratory function in resting adults. Rates outside of this range can indicate potential respiratory or underlying health issues: a rate lower than 12 may suggest bradypnea, while a rate higher than 20 may indicate tachypnea.

This range is established based on physiological norms and is used as a vital sign during medical assessments to ensure that a patient’s breathing is adequate for their metabolic needs. Monitoring the respiratory rate is essential as it provides insights into a person's condition and overall health.
