Which is the most suitable technique for a patient with muscular dystrophy and pneumonia who struggles to expectorate secretions?

In the case of a patient with muscular dystrophy and pneumonia who is having difficulty expectorating secretions, the use of Intermittent Positive Pressure Ventilation (IPPV) is particularly suitable. IPPV plays a crucial role in aiding ventilation and can assist in mobilizing secretions in patients who have compromised respiratory mechanics, like those with muscular dystrophy. This technique enhances airway pressure to help expand the lungs, improving ventilation and potentially facilitating the process of mucus clearance.

Patients with muscular dystrophy often experience muscle weakness affecting their ability to cough effectively, thereby requiring a more supportive approach to maintain adequate respiratory function and clearance of secretions. IPPV can help offset the inadequate respiratory efforts due to weakened respiratory muscles and may also assist in ensuring adequate oxygenation, which is vital in the setting of pneumonia.

Other methods, although beneficial in various situations, may not be as effective. For instance, postural drainage and percussion rely heavily on the patient's ability to cough and cooperate actively, which may not be feasible for those with significant muscle weakness. Similarly, while techniques like huff coughing and Vibratory PEP therapy can promote mucus clearance, they may not provide the same level of respiratory support and assistance in secretion management as IPPV does, particularly in an acute
