What is the normal range for adult respiratory rate?

The normal range for adult respiratory rate is between 12 to 20 breaths per minute. This range is considered typical for a resting adult and reflects the body's need for oxygen while eliminating carbon dioxide efficiently. A respiratory rate falling within this range indicates effective ventilation and overall respiratory health.

Rates lower than 12 breaths per minute may indicate bradypnea, which can occur in conditions such as drug overdose or severe respiratory distress, while rates above 20 breaths per minute may suggest tachypnea, often seen in states of anxiety, fever, or respiratory conditions. Understanding this normal range is crucial for monitoring a patient’s respiratory status effectively.
