What is the adult respiratory rate range considered normal?

The adult respiratory rate range considered normal is 12 to 20 breaths per minute. This range is established based on physiological studies and clinical observations that define the typical breathing patterns in healthy adults at rest.

Breathing within this range is crucial for effective gas exchange in the lungs, ensuring that the body receives adequate oxygen and effectively eliminates carbon dioxide. Rates below 12 breaths per minute may indicate bradypnea, which could suggest respiratory depression, while rates above 20 breaths per minute could signal tachypnea, indicating potential respiratory distress or other underlying medical conditions.

Recognizing the normal respiratory rate is essential in clinical practice, as deviations can help healthcare providers assess and respond to a patient's respiratory status promptly.
