What is the normal range for adult respiratory rate?

The normal range for adult respiratory rate is 12-20 breaths per minute. This range reflects the typical rate of breathing for a healthy adult at rest and is considered vital for maintaining adequate oxygenation and carbon dioxide elimination. Within this range, the body can efficiently manage gas exchange, ensuring that tissues receive adequate oxygen and that carbon dioxide is expelled effectively. Rates outside this normal range can be indicative of various health issues; for instance, rates lower than 12 may suggest bradypnea or respiratory depression, while rates higher than 20 can indicate tachypnea, often seen in conditions such as anxiety, fever, or respiratory distress. Understanding this normal range is crucial for nursing assessments, as deviations can provide early signs of potential respiratory compromise or other medical concerns.
