How can you determine if a patient is breathing adequately?

• A. Breathing rate of 6 to 8 breaths per minute
• B. Chest rising and falling with a rate of 12 to 20 per minute
• C. Clear lungs on auscultation
• D. Absence of chest movement indicates adequacy

Answer: (B)

Adequate breathing is shown by visible chest rise and fall with a normal breathing rate for an adult, about 12 to 20 breaths per minute. This combination demonstrates that air is moving in and out of the lungs at a typical, adequate pace. If the rate is too slow, such as 6 to 8 breaths per minute, ventilation may be insufficient even if some chest movement is present. Clear lungs on auscultation doesn’t guarantee adequate ventilation, because you could still be moving air at an abnormal rate or with shallow depth. And if there’s no chest movement at all, there’s no ventilation happening. So, observing chest rise and fall and ensuring the rate falls within the normal range is the best way to assess adequacy of breathing.
