Physical Examination

Pneumomediastinum is uncommon, it occurs when air leaks from any part of the lung or airways into the mediastinum and is often recognized on auscultation by a "crunching" sound timed with the cardiac cycle (Hamman's crunch). Subcutaneous emphysema is one of the symptoms of pneumomediastinum.
