A lung transplant is a useful treatment for respiratory disease that has curtailed the lung function severely. In such patients, a lung transplant can increase longevity and also help improve quality of life. However, lung transplant surgery is a complex procedure needing cutting edge facility and care. Severe, end-stage lung disease is a strong indication for a lung transplant. The procedure should be considered when all other treatment modalities have failed and also in people whose lung disease is so severe that they can no longer live and breathe comfortably.
