Signs and Symptoms
Bronchiolitis obliterans is a lung disease characterized by fixed airway obstruction. Inflammation and scarring occur in the airways of the lung, resulting in severe shortness of breath and dry cough.
FEV1 (forced expiratory volume in 1 second) should be above 80% of predicted values to be considered normal. Bronchiolitis obliterans reduces this to 16% to 21%.
Symptoms include:
- dry cough
- shortness of breath
- wheezing
The symptoms can start gradually, or severe symptoms can occur suddenly.
