What is the normal range for adult respiratory rates?

The normal range for adult respiratory rates is typically considered to be between 12 to 20 breaths per minute. This range reflects the average respiratory activity in a resting adult human being. It is essential to understand that respiratory rate can vary based on multiple factors such as age, fitness level, and health status. For most adults, maintaining a respiratory rate within this range indicates adequate lung function and oxygenation of the body. When assessing a patient, noting the respiratory rate helps to evaluate their respiratory health and can indicate whether further medical evaluation may be necessary.
