In an 8-year-old with cystic fibrosis on positive expiratory pressure therapy who develops a middle ear infection, what should be recommended?

• A. Continue therapy at a reduced resistance
• B. Change to an external percussive device
• C. Administer IPPB with Pulmozyme
• D. Instruct the patient in huff coughing

Answer: (B)

When a child with cystic fibrosis develops a middle ear infection, it’s important to avoid airway clearance methods that increase expiratory pressure, because that pressure can be transmitted via the Eustachian tube to the middle ear and potentially worsen the infection or cause discomfort. Positive expiratory pressure therapy does exactly that—it creates resistance during exhalation and raises airway pressures, which can affect the ears. An external percussive device, such as high-frequency chest wall oscillation, clears mucus through chest wall vibrations without requiring positive expiratory pressure. It provides effective airway clearance while minimizing pressure changes that could aggravate the middle ear infection, making it the most appropriate choice in this scenario. Continuing therapy with reduced resistance would still involve expiratory pressure. Intermittent positive pressure breathing would also raise airway pressures and could worsen the ear condition. Huff coughing alone helps loosen mucus but is typically not as effective for CF clearance as oscillatory or vest-based methods, especially during an active infection.
