Cardiac and pulmonary integration monitoring
Assessment for pulmonary hypertension and right heart function, which commonly develop secondary to chronic respiratory compromise. Echocardiography and right heart catheterization may be indicated.
Additional treatment options
Lung transplantation evaluation and consideration
Assessment for lung transplantation in end-stage respiratory failure when other interventions fail. Reserved for severe cases with progressive deterioration.
surgicalEnvironmental modification and infection prevention
Home modifications including air filtration, humidity control, and avoidance of respiratory irritants. Also includes vaccination compliance and avoidance of sick contacts.
