Is the medical term for air in the chest cavity?

A pneumothorax is a collection of free air in the chest cavity (thoracic cavity) that causes the lung to collapse. Pneumothorax may occur on its own in the absence of underlying disease; this is termed spontaneous pneumothorax. Pneumothorax may also occur because of an injury or underlying lung disease.

What is the medical term for air in the chest?

It may also occur spontaneously without apparent cause.
