Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Medication management with follow-up
Active treatment with regular monitoring by a healthcare provider is recommended.
Thoracic expansion surgery
Surgical procedure to expand the thoracic cavity and improve respiratory function by modifying rib cage structure. This is a complex intervention typically considered when conservative measures fail to maintain adequate oxygenation.
Respiratory function monitoring
Regular assessment of lung function, oxygen saturation, and respiratory effort through polysomnography and pulmonary function tests. Early detection of respiratory compromise allows for timely intervention.
Additional treatment options
Non-invasive positive pressure ventilation
Application of CPAP or BiPAP devices to maintain airway patency and improve gas exchange during sleep and potentially during waking hours. Often initiated when nocturnal hypoventilation is detected.
procedureRespiratory infection management
Aggressive treatment and prevention of pulmonary infections through antibiotics and clearance therapies. Airway clearance techniques help prevent mucus accumulation in compromised lungs.
medicationChest physiotherapy and pulmonary rehabilitation
Specialized physical therapy techniques including postural drainage, percussion, and breathing exercises to improve lung expansion and secretion clearance. Ongoing therapy maintains respiratory function.
