What term describes respiratory rate below 12 breaths per minute?

• A. Apnea
• B. Labored Breathing
• C. Rales
• D. Bradypnea

Answer: (D)

Bradypnea describes a slower-than-normal breathing rate, defined as fewer than 12 breaths per minute in adults. Normal breathing is usually about 12–20 breaths per minute, so dipping below 12 fits bradypnea. This contrasts with apnea, which is a complete halt in breathing; labored breathing, which means increased effort and work to breathe; and rales, which are abnormal crackling sounds heard in the airways. Recognizing bradypnea helps identify potential issues with the respiratory or nervous system and the risk of insufficient ventilation if the rate is too slow.
