Which breathing technique is commonly used during exercise for emphysema?

• A. Pursed-lip breathing
• B. Rapid, shallow breathing
• C. No breathing technique
• D. Vibration therapy

Answer: (C)

During exercise for emphysema, using breathing techniques that improve air flow and reduce breathlessness is important. Pursed-lip breathing fits this goal perfectly because it creates a little resistance when you exhale. That resistance helps keep the airways open longer, slows down exhalation, and reduces air trapping. As a result, more complete breaths can occur, gas exchange improves, and the effort of breathing during activity decreases, which can boost endurance and comfort. Rapid, shallow breathing tends to worsen air trapping and dyspnea, since it doesn't effectively empty the lungs. Not using any technique misses a simple, effective way to optimize ventilation during effort. Vibration therapy is mainly for loosening mucus rather than guiding breathing during exercise.
