Nonpharmacologic strategies essential to maintain respiratory function in muscular dystrophy?

• A. Airway clearance techniques, chest physiotherapy, regular pulmonary rehabilitation, and noninvasive ventilation when indicated
• B. Vaccinations
• C. Bed rest
• D. Antibiotics

Answer: (A)

Maintaining respiratory function in muscular dystrophy relies on techniques that actively help clear airways and support ventilation, rather than relying on drugs or prolonged rest. Airway clearance techniques and chest physiotherapy directly improve how air moves and how mucus is removed, reducing the risk of atelectasis and infection. Regular pulmonary rehabilitation builds endurance and strengthens respiratory muscles, improves chest expansion, and enhances overall conditioning, which helps sustain breathing efficiency. When there are signs of insufficient ventilation, noninvasive ventilation provides breathing support without invasive procedures, helping maintain gas exchange during sleep and periods of daytime fatigue.

Vaccinations help prevent respiratory infections and are important for overall lung health, but they do not directly maintain respiratory mechanics. Bed rest tends to weaken muscles and reduce conditioning, which is the opposite of what’s needed. Antibiotics treat infections but do not preserve respiratory function on their own.
