How many breaths does a typical adult take per minute?

• A. 12-20
• B. 8-12
• C. 20-30
• D. 30-40

Answer: (A)

Normal resting breathing for an adult is about 12 to 20 breaths per minute. This range represents quiet, effortless breathing at rest, providing enough oxygen and removing carbon dioxide without extra effort. Breathing slower than this (around 8 to 12) is slower than typical resting rate and can indicate bradypnea, while breathing faster (20 to 30 or 30 to 40) is faster than typical resting rate and can indicate tachypnea, often associated with fever, illness, hypoxia, pain, or anxiety. So, a typical adult takes roughly 12–20 breaths per minute.
