What is considered a normal respiratory rate in adults?

Eupnea refers to a normal, unlabored breathing pattern characterized by a regular respiratory rate that is appropriate for the individual’s age and health status. In adults, the typical respiratory rate is generally between 12 to 20 breaths per minute. This rate supports adequate gas exchange and reflects a stable state of respiratory function.

In contrast, bradypnea indicates an abnormally slow respiratory rate, which can be caused by various factors such as certain medications, metabolic disorders, or damage to the respiratory center in the brain. Tachypnea involves an increased respiratory rate, often seen in situations such as anxiety, exercise, or respiratory illnesses, which can signal distress or an underlying health issue. Apnea refers to a temporary cessation of breathing, which is not consistent with normal respiratory function and can be indicative of a serious medical condition.

Thus, eupnea is the only term that accurately describes a normal and healthy respiratory state in adults, making it the correct choice.
