What would you expect the respiratory rate of a resting adult to be?

The expected respiratory rate of a resting adult typically falls within the range of 12 to 20 breaths per minute. This range is considered normal and reflects an efficient respiratory system that adequately meets the body's oxygen demands at rest. Breathing occurs in an automatic, rhythmic manner, and within this rate, the individual is likely to have a steady, comfortable pattern of inhalation and exhalation, optimizing gas exchange in the lungs.

A respiratory rate below 8 breaths per minute could indicate bradypnea, which may signal respiratory depression or an underlying medical condition requiring further investigation. Similarly, rates above 25 breaths per minute or around 30 breaths per minute suggest tachypnea, which often occurs during exertion, stress, fever, or respiratory distress. Both of these scenarios surpass the normal range and typically indicate a physiological response to conditions that require more oxygen or involve increased respiratory effort. Thus, the range of 12 to 20 breaths per minute is the standard for assessing normal respiratory function in a resting adult.
