A healthy adult at rest breathes at about which rate?

Explanation:
Resting breathing rate reflects how many breaths a person takes per minute while not exerting effort. For a healthy adult at rest, the standard benchmark is about 12 to 20 breaths per minute. This range is what EMS clinicians use to assess normal ventilation without distress. Rates lower than this, such as 6 to 12, suggest bradypnea and can indicate depressant effects, fatigue, or high fitness in some cases; rates higher than this, such as 22 to 28, suggest tachypnea and can point to fever, hypoxia, anxiety, or pulmonary/airway problems. The 12–20 window best matches the typical resting rate, making it the correct choice.
