Respiratory failure
Cystic fibrosis severely affects the lungs and damages lung tissues to the point where the lungs cease functioning. Due to the persistent obstruction of bronchial tubes, the lungs’ functions deteriorate progressively. If not correctly treated, the mucus can clog the lungs, making it very difficult to breathe. It can be life-threatening and can lead to respiratory failure, the leading cause of mortality. In this situation, it is necessary to replace the lungs in order to save the patient’s life.
