What is the typical adult respiratory rate?

The typical adult respiratory rate is primarily 12 to 20 breaths per minute. This range is considered normal for a resting adult and can vary based on factors such as activity level, health status, and age. A respiratory rate within this range indicates that the body is effectively taking in oxygen and expelling carbon dioxide during the breathing process.

When assessing a patient's respiratory rate, it's crucial to ensure that it falls within this normal range for adequate respiratory function. Rates outside of this range, such as those indicated in the other choices, could suggest potential medical issues. For example, a rate below 12 breaths per minute may indicate bradypnea, while a rate exceeding 20 breaths per minute could denote tachypnea, both of which may require further evaluation or intervention.
