• Erect CXR—blunting of hemidiaphragm and progressive loss of basal lung field

• Supine CXR—increased opacity of affected hemithorax plus decreased clarity of cardiac contour on that side.

• Large bore needle aspiration to confirm presence of blood. A small bore needle may be unable to aspirate a haemothorax if it has clotted.
