😮‍💨Pursed-lip breathing is a key technique that helps clients with emphysema improve gas exchange by promoting longer exhalation, reducing air trapping, and maintaining positive airway pressure, which keeps alveoli open longer.

👃Breathing in through the nose warms, filters, and humidifies the air, which is also beneficial for lung function.

🛏️Resting in a supine position can impair ventilation in clients with emphysema; they breathe more effectively in high Fowler's or tripod positions.

🥩A low-protein diet is not advised—clients with COPD or emphysema need adequate protein intake to maintain muscle strength, including respiratory muscles.

💧Limiting fluid intake is not appropriate; clients should have adequate hydration to help thin secretions, aiding in their expectoration and improving ventilation.

📌Core Message

Pursed-lip breathing supports better ventilation and gas exchange in emphysema by reducing air trapping and enhancing airflow.
