The presence of air in mediastinal soft tissues.
Clinical findings
Severe chest pain, dyspnoea, Hamman sign.
Aetiology
• Respiratory tract—trauma to lungs, perforation of upper airways, asthma, Mycoplasma pneumoniae pneumonia.
• GI tract—rupture of oesophagus, bowel.
• Other (e.g., obesity).

Management
Usually conservative, as emphysema slowly resolves on its own; in the face of lung collapse, the patient must lie on the side of the collapsed lung.
