Obstructed airways: I think context would be helpful in order to answer this question satisfactorily. Air trapping is a symptom or sign of obstructed airways where the air has an easier time getting in than out. Conditions like COPD, Emphysema and Asthma are the usual causes and can be seen on xray as flattening of the diaphragm and on spirometry as a increased Functional Residual Capacity. Other causes are rare.
