FIGURE 99.3 Chest radiograph showing pneumothorax If pneumothoraces are recurrent or persistent, the patient should be evaluated for pleurodesis While this may prevent recurrence, such intervention may have implications for lung transplant eligibility and should be discussed with physicians having experience in either CF or lung transplantation Daily CF therapies, such as chest percussion and postural drainage, oscillatory percussive vest therapy, other airway clearance techniques (e.g., positive expiratory pressure [PEP] mask, flutter valve), inhalation of dornase alfa (pulmozyme), and pulmonary function testing, should be suspended temporarily to avoid exacerbating the pneumothorax Inhalational therapy with bronchodilators and/or ICSs may be continued with nebulization, but the usual inhalational maneuvers with MDIs probably should be avoided until the
