Tachypnea is generally identified when the respiratory rate exceeds how many breaths per minute?

Explanation:
Tachypnea means abnormally rapid breathing. In adults at rest, normal breathing is typically about 12 to 20 breaths per minute. If the rate exceeds 20 breaths per minute, we call it tachypnea. The numbers at the higher end (such as 30 or 40) describe more severe tachypnea, but the threshold used to identify tachypnea is simply over 20. This change signals increased work of breathing or an underlying issue such as fever, hypoxemia, pain, anxiety, or a metabolic or respiratory problem, so it prompts further assessment of oxygenation and respiratory effort.
