What breathing rate signifies inadequate breathing in adults?

In adults, a breathing rate of less than 12 or more than 20 breaths per minute is generally considered indicative of inadequate breathing. The normal respiratory rate for a healthy adult typically ranges from 12 to 20 breaths per minute. When a person breathes less than 12 times per minute (bradypnea) or more than 20 times (tachypnea), it can reflect underlying respiratory distress or inadequate ventilation.

Low respiratory rates may lead to insufficient oxygen intake and carbon dioxide retention, while high rates can suggest an attempt to compensate for reduced oxygen or increased carbon dioxide levels in the blood. Monitoring breathing rates is essential in assessing overall respiratory function and identifying potential respiratory failure or significant distress.
