What is the term for a respiratory rate that is slower than normal?

The term for a respiratory rate that is slower than normal is referred to as bradypnea. This condition is characterized by a lower than usual respiratory rate, commonly defined as fewer than 12 breaths per minute in adults. Bradypnea can be indicative of various medical conditions, such as certain respiratory disorders, neurological issues, or the effects of certain medications. Understanding this term is crucial for health professionals as it helps in assessing a patient's respiratory function and overall health.

In contrast, tachypnea refers to an abnormally rapid respiratory rate, typically more than 20 breaths per minute in adults. The terms afebrile and febrile are related to body temperature; afebrile indicates the absence of fever, while febrile indicates the presence of fever. These terms do not relate directly to calculating or assessing respiratory rates.
