Question

Quizplus · Accepted Answer

A variety of mechanisms can cause a pneumothorax.A traumatic pneumothorax develops as a result of penetrating chest trauma,such as a stabbing or a case of the chest striking the steering wheel in an automobile accident.A spontaneous or primary pneumothorax sometimes occurs from the rupture of a small bleb (blister)on the surface of the lung or from an invasive procedure,such as insertion of a subclavian intravenous (IV)line.Secondary pneumothorax occurs because of underlying disease,such as emphysema.A patient with a pneumothorax usually feels pain as atmospheric air irritates the parietal pleura.Dyspnea is a symptom of pneumothorax,not a cause.
