Could i get some information on a spontaneous pneumothorax?

Collapsed lung: Spontaneous pneumothorax is collapse of the lung due to air leaking out from the lung. Spontaneous means that there is no obvious cause such as trauma. In most cases, it would be treated initially with a chest tube, which will allow the lung to re-expand. If it re-occurs or if the air leak does not seal, sometimes surgery is necessary.

Pneumothorax: A pneumothorax is air that is trapped next to a lung. The common symptom is a sudden sharp chest pain followed by pains when you breathe in. You may become breathless. In most cases, the pneumothorax clears without needing treatment. The trapped air of a large pneumothorax may need to be removed if it causes breathing difficulty.
