What is the normal adult respiratory rate?

The normal adult respiratory rate typically ranges from 12 to 20 breaths per minute. This range is considered the baseline for a resting adult under normal circumstances. A rate within this range indicates that the body's demand for oxygen is being met efficiently, reflecting an effective respiratory system.

Breathing rates outside of this range may signify various medical conditions. For instance, a respiratory rate below 12 could suggest bradypnea, while a rate above 20 might indicate tachypnea, both of which can warrant further assessment by healthcare professionals. The importance of recognizing the normal respiratory rate lies in its role as a vital sign that helps determine a patient's respiratory health and informs clinical decision-making.
