Key points- A plain PA or AP radiograph generally underestimates the size of a pneumothorax.
- Simple aspiration is recommended as a first-line treatment for all primary pneumothoraces requiring intervention in the spontaneously breathing patient without CPAP.
- Patients who develop a pneumothorax while on positive pressure ventilation or CPAP should be treated with a chest drain unless immediate weaning from positive pressure ventilation is possible.
- A thoracic surgical opinion should be sought in cases of persistent large volume air leaks or failure of the lung to re-expand significantly within 4 days.
- Except in rare cases of tension, air emphysema and pneumomediastinum are not life threatening and need observation only.
- Tension pneumothorax is an unusual but a recognized cause of respiratory and cardiovascular compromise during anaesthesia and surgery.

Air leaks can be defined as any extrusion of air from normal gas-filled cavities including the upper airway, sinuses, tracheobronchial tree, and gastrointestinal (GI) . . . [Full Text of this Article]
