What are the risks and recovery expectations after Zephyr valve placement?

Common risks include pneumothorax (lung collapse, occurring in up to 20% of cases), valve migration or expectoration, and exacerbation of COPD. Serious but rare complications include hemoptysis or empyema. Recovery involves a 5–7 day hospital stay for monitoring, followed by 4–6 weeks of gradual activity increase. Most patients notice improved breathing and exercise tolerance within weeks, though full benefit may take 3 months. Follow-up includes chest X-ray and pulmonary function tests.
