What respiratory rate indicates an adult is in the normal range?

A respiratory rate of 12-20 breaths per minute is considered the normal range for adults. This range reflects the typical respiratory drive and metabolic demands of a healthy individual at rest. Breathing within this range indicates adequate ventilation and oxygenation, which are crucial for maintaining homeostasis.

When assessing a patient's respiratory rate, it's important to consider factors such as age, activity level, and overall health. A rate below 12 breaths per minute may suggest respiratory depression or other medical conditions, while rates above 20 breaths per minute could indicate increased metabolic demand, anxiety, pain, or respiratory distress. Therefore, understanding what constitutes a normal respiratory rate helps healthcare providers identify potential respiratory issues early and respond accordingly.
