What is the typical range for respiratory rate in adults?

The typical range for respiratory rate in adults is 12 to 20 breaths per minute. This range is considered normal for resting adults, as it reflects the body's metabolic demands and the need for oxygenation and carbon dioxide elimination. Respiratory rates outside of this range may indicate abnormal physiological states.

A rate lower than 12 breaths per minute may suggest bradypnea, which can occur in conditions like drug overdose or respiratory depression. In contrast, a rate higher than 20 breaths per minute indicates tachypnea, which could be a sign of conditions such as anxiety, fever, or respiratory distress. Understanding this normal range is essential for healthcare providers to assess respiratory status effectively and respond appropriately to any deviations.
