What is the normal range for adult resting respiratory rate?

The normal range for adult resting respiratory rate is considered to be between 12 and 20 breaths per minute. This range reflects the typical frequency of breaths taken while at rest and encompasses the physiological needs of an adult at rest under normal conditions. Factors such as age, fitness level, and overall health can influence an individual's resting respiratory rate; however, for most adults, staying within this range is indicative of proper respiratory function.

When assessing respiratory rates, it's important to remember that rates lower than 12 breaths per minute may indicate bradypnea, which can be associated with certain medical conditions or depressant drug use. Conversely, rates above 20 breaths per minute may indicate tachypnea, which could arise from factors such as anxiety, exercise, or respiratory issues. Understanding this normal range is essential for healthcare professionals in evaluating respiratory health in patients.
