Which breathing technique is commonly taught to COPD patients to improve ventilation?

• A. Pursed lip breathing
• B. Nasal breathing
• C. Shallow breathing
• D. Forced rapid breathing

Answer: (A)

In COPD, managing how air leaves the lungs is crucial because airway narrowing and loss of elastic recoil lead to air trapping and increased work of breathing. Pursed-lip breathing is taught because it creates a small amount of back pressure during exhalation. This back pressure helps keep the smaller airways open longer, slows the exhale, and reduces dynamic hyperinflation. With a controlled, slower outflow, ventilation becomes more efficient and the sensation of breathlessness often decreases, especially during activity. To use it, breathe in gently through the nose, then exhale through pursed lips, making the exhale longer than the inhale (often two to three times as long). This simple technique directly addresses the expiratory phase that COPD patients struggle with. Other options aren’t tailored to this expiratory problem: nasal breathing is just a normal pattern and doesn’t specifically address airway collapse during exhalation; shallow breathing lowers overall ventilation and can worsen gas exchange; forced rapid breathing increases work of breathing and air trapping.
