What is the correct term for the condition of a decreased respiratory rate?

1. Hypopnea

2. Bradypnea

3. Tachypnea

4. Apnea

The correct answer is: Bradypnea

The condition characterized by a decreased respiratory rate is known as bradypnea. This term specifically refers to a slower than normal breathing rate, which can be indicative of various medical conditions or responses to medications, especially those that depress the central nervous system. Hypopnea refers to shallow breathing and is not directly associated with the rate of breaths per minute; instead, it focuses more on the depth of each breath, making it distinct from bradypnea. Tachypnea, on the other hand, denotes an increased respiratory rate and is often linked to conditions that necessitate greater oxygen intake or clearance of carbon dioxide. Apnea signifies a temporary cessation of breathing and is typically a more severe condition distinguished from the gradual reduction in rate that bradypnea represents. Understanding these specific definitions helps identify the correct term for decreased respiratory rate as bradypnea.
