Question

Normal range of breathing rate per minute in an average adult person at rest is
1. 9 - 12
2. 12 - 20
3. 21 - 24
4. 30 - 33

Answer 1

Correct Answer - Option 2 : 12 - 20

The correct answer is 12 - 20

• The normal range of breathing rate per minute in an average adult person at rest is 12 - 20.

• Breathing (or ventilation) is the process of moving air into and out of the lungs to facilitate gas exchange with the internal environment, mostly by bringing in oxygen and flushing out carbon dioxide.
• Respiratory rate:
  • A person's respiratory rate is the number of breaths you take per minute.
  • The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.
  • A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal.
  • Among the conditions that can change a normal respiratory rate are asthma, anxiety, pneumonia, congestive heart failure, lung disease, use of narcotics or drug overdose.
