An abnormal state characterized by the presence of gas (as air) in the pleural cavity.

The introduction of air into the pleural cavity.

When there is air between the lung and chest wall if a lung has leaked air.

Free air in the chest outside the lung.  It can occur spontaneously (out of the blue, with or without underlying lung disease), following a fractured rib, chest surgery, or be deliberately induced in order to collapse the lung. A small pneumothorax without underlying lung disease may resolve on its own. A larger pneumothorax or one associated with underlying lung disease often requires aspiration of the free air and/or placement of a chest tube to evacuate the air and allow lungs to re-expand.

abnormal accumulation of air or gas in the pleural space (the space surrounding the lungs)

A sudden, partial or complete collapseof the lung. Results from the rupture of lung tissue, which allows air to escape from the lung and become trapped between the lung and the chest wall.

free air in the pleural cavity, between the visceral and parietal pleura.

Leakage of air in the pleural cavity from the lungs

Leaking of air from the lung into the chest cavity, causing the lung to collapse.

air in the chest cavity from injury to the lung

a collection of air between the outside surface of the lung and

a common sequela of blunt trauma

a condition in which air escapes from the lung and causes the lung to collapse

a lung disorder in which air in the lungs leaks out through holes in the lung tissue into the spaces outside the lung airways

an accumulation of air or gas in the pleural cavity, occurring as a result of disease or injury, or sometimes induced to collapse the lung in the treatment of tuberculosis and other lung diseases

an important cause of chest pain

a pocket of air between the two layers of pleura, resulting in collapse of the lung

a rupture in the lungs that allow air to seep between the lungs and the chest wall and can cause the lung to collapse

Medical term describing the presence of air inside the chest cavity, between the lung and the chest wall caused traumatically by broken ribs or an object puncture or cased during an operation when the lung is injured. It can be treated with a chest tube. – No Relevant Terms

An injury to a lung such that air is present in the pleural cavity.

A dangerous condition when air enters the chest cavity causing a lung to collapse, usually the result of penetrating trauma, i.e. bullets, knives etc.

This literally means air in the chest. It is caused by a punctured Lung which then collapses. May be due to injury or happen spontaneously.

presence of air in the chest cavity.

An accumulation of air in the chest cavity that results from a rupture in the lungs.

condition in which air escapes from a damaged lung and enters the area between the chest wall and the lung

The accumulation of air or gas in the pleural cavity.

collapse of the lung, often spontaneously Back to the top

A condition in which air escapes from the lungs into the chest cavity and pushes on the lungs.

Collection of air in the pleural cavity which causes the lung to collapse. Air has gained entry through a lesion in the lung or wound in the chest wall.

presence of air in the pleural cavity, caused by a rupture of the plural membrane or by trauma through the chest wall.

The presence of air between the outer lining of the lung and the chest wall, which causes the lung to collapse.

is a collection of air or gas in the lung linings and causing the lung to collapse

Free air in the pleural space; may be modified by the following descriptive terms" hydro-, pyo-, hemo-, chylo-, tension.

Collapsed lung, with air in the chest cavity.

a condition characterized by collapse of the lung due to rupture of the membrane covering the lung and subsequent escape of air into the pleural space; usually a result of a penetrating injury or a complication of pulmonary tuberculosis or emphysema.

A surgical method to collapse a lung. The space between the lung and the chest wall is filled with air, so the lung muscles are less active.

air within the chest cavity.

air becomes trapped in the pleural space (the area between the lung and the chest wall); causes the lung to collapse.

Abnormal presence of air in the pleural cavity potentially resulting in the collapse of the lung.

Accumulation of air or gas in the space between the lung and chest wall, resulting in partial or complete collapse of the lung.

The presence of air or gas in space that holds the lungs.

A partial or complete collapse of the lung resulting from the abnormal entry of gas into the pleural cavity.

abnormal collection of air outside the lining of the lung, between the lung and the chest wall, often a consequence of barotraumas.

Accumulation of air or gas in the pleural cavity resulting in partial or complete collapse of the lung.

air or gas in the pleural cavity resulting from a free communication between the atmosphere and the pleural space either via the lung or the chest wall.

Air in the pleural cavity. It may cause the lung to collapse.

Free air in the chest outside the lung. See the entire definition of Pneumothorax

Accumulation of air within the pleural cavity, inside the chest but outside the lungs, impeding the ability of the lungs to expand normally; collapsed lung.

A collection of air or gas in the pleural cavity.

("collapsed lung") - A rupture in the lung. Pneumothorax is a collection of air in the chest resulting from a tear in the air sac of a baby's lung, causing air to leak out of the lung into the space between the lung and the chest wall.  It can put pressure on the opposite lung and the heart causing the blood oxygen and the blood pressure to fall.

Accumulation of air between the outer lining of the lung and the chest wall, causing collapse of the lung.

Air that escapes from the lung into the pleural space in the chest.

a collection of air or gas in the pleural space causing the lung to collapse.

Literally, air in the chest. A collection of air or gas in the chest cavity that causes part or all of one of the lungs to collapse.

The build-up of air or gas in the chest cavity. May cause lung collapse.

Pneumothorax occurs when a cyst in the lung ruptures, creating a small hole in the lining of the lung that allows air to escape into the surrounding chest cavity, causing the lung to collapse. This condition requires immediate medical attention.

air leaks into the space between the chest wall and the outer tissues of the lungs.

Air or gas in the pleural cavity that can cause a collapse of the lung if not treated

In medicine (pulmonology), a pneumothorax is a potential medical emergency caused by accumulation of air or gas in the pleural cavity, occurring as a result of disease or injury.
