The cause of primary spontaneous pneumothorax is unknown, but established risk factors include being of the male sex, smoking, and a family history of pneumothorax. [18] Smoking either cannabis or tobacco increases the risk. [3] The various suspected underlying mechanisms are discussed below. [12] [13]
There are several causes for a tracheal deviation, and the condition often presents along with difficulty breathing, coughing and abnormal breath sounds. The most common cause of tracheal deviation is a pneumothorax, which is a collection of air inside the chest, between the chest cavity and the lung. A pneumothorax can be spontaneous, caused ...
[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]
Causes include any obstruction of blood flow to and from the heart. There are multiple, including pulmonary embolism, cardiac tamponade, and tension pneumothorax. Other causes include abdominal compartment syndrome, Hiatal hernia, severe aortic valve stenosis, and disorders of the aorta. Constrictive pericarditis is a rare cause.
The most common symptom is sudden pain in one side of the lung and shortness of breath. A pneumothorax also can put pressure on the lung and cause it to collapse. If the pneumothorax is small, it may go away on its own. If large, a chest tube is placed through the skin and chest wall into the pleural space to remove the air.
In the emergency department the typical approach to chest pain involves ruling out the most dangerous causes: heart attack, pulmonary embolism, thoracic aortic dissection, esophageal rupture, tension pneumothorax, and cardiac tamponade. By elimination or confirmation of the most serious causes, a diagnosis of the origin of the pain may be made.
Catamenial pneumothorax is a spontaneous pneumothorax that recurs during menstruation, within 72 hours before or after the onset of a cycle. [1] It usually involves the right side of the chest and right lung, and is associated with thoracic endometriosis . [ 2 ]
Left tension pneumothorax with a large, well-demarcated area devoid of lung markings with tracheal deviation and movement of the heart away from the affected side. Mediastinal shift is an abnormal movement of the mediastinal structures toward one side of the chest cavity .
