What term describes a condition where one is experiencing a respiratory rate that is less than normal?

The condition characterized by a respiratory rate that is less than normal is known as bradypnea. This term is derived from the prefix "brady-" which means slow, and "pnea," meaning breathing. Normal respiratory rates for adults typically range from 12 to 20 breaths per minute. When an individual breathes at a rate below this threshold, it is referred to as bradypnea.

This condition can be indicative of various health issues, such as respiratory depression or neurological conditions, and it may also be a result of certain medications or metabolic abnormalities. Recognizing bradypnea is important as it can help healthcare providers assess a patient's respiratory status and overall health.

The other terms provided, while related to respiratory or cardiovascular conditions, do not define a slow respiratory rate. Tachypnea describes an increased respiratory rate, febrile refers to having a fever, and arrhythmia pertains to irregularities in heart rhythm. Understanding these distinctions is essential for correctly identifying and managing various medical conditions.
