Spontaneous pneumothorax is, as in humans, classified as primary or secondary, while traumatic pneumothorax is divided into open and closed (with or without chest wall damage). [63] The diagnosis may be apparent to the veterinary physician because the animal exhibits difficulty breathing in, or has shallow breathing.
A pneumothorax, also known as a collapsed lung, is a collection of air outside the lung in the pleural cavity. [14] Depending on etiology, a pneumothorax is classified as spontaneous, traumatic and iatrogenic. A spontaneous pneumothorax is further classified as primary and secondary, with the former occurring in individuals with no clinical ...
[citation needed] An abrupt worsening in COPD symptoms may cause rupture of the airways in the lungs, which in turn may cause a spontaneous pneumothorax. [4] In infection, there is often weakness, fever and chills. If due to a bacterial infection, the sputum may be slightly streaked with blood and coloured yellow or green. [5]
In regard of the low incidence of primary spontaneous pneumothorax (i.e. not due to surgical trauma etc.) in women (about 1/100'000/year), [16] this is a very rare condition. Hence, many basic textbooks do not mention it, and many doctors have never heard of it. Therefore, catamenial pneumothorax is probably under-recognized. [17]
LAM is sometimes revealed by chest CT in patients who present with an apparent primary spontaneous pneumothorax, but more often CT scanning is not ordered (in the United States) until recurrences occur. Progressive dyspnea on exertion without the exacerbations and remissions that are characteristic of asthma or COPD sometimes prompt a chest CT.
Uptodate says "A primary spontaneous pneumothorax (PSP) is a pneumothorax that occurs without a precipitating event in a person who does not have known lung disease. In actuality, most individuals with PSP have unrecognized lung disease, with the pneumothorax resulting from rupture of a subpleural bleb".
Those with an abnormal accumulation of air within the pleural space (a pneumothorax) can bleed into the cavity, which occurs in about 5% of cases of spontaneous pneumothorax, [8] especially when lung bullae rupture. [11] The resulting combination of air and blood within the pleural space is known as a hemopneumothorax. [8]
Left-sided tension pneumothorax. Note the area without lung markings which is air in the pleural space. Also note the tracheal and mediastinal shift from the patient's left to right. Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax.
