![]() Patients with large pneumothorax who seek treatment within a short time of the onset and present more severe symptoms may require placement of a chest tube (inserted between the ribs) to release the tension. If the imaging reveals only a small pneumothorax, the patient may only require oxygen supplementation and observation in the hospital for a brief period of time. Patients who seek treatment for minimal or resolving symptoms after more than 24 hours will receive a chest X-ray to determine treatment. Other risk factors include connective tissue disorders, smoking, and activities such as scuba diving, high altitudes and flying. Tall and thin adolescent males are typically at greatest risk, but females can also have this condition. ![]() In most cases of spontaneous pneumothorax, the cause is unknown. A small spontaneous pneumothorax may resolve without treatment, while larger pneumothorax may need surgical intervention. Spontaneous pneumothorax can be either small or large. In most cases of spontaneous pneumothorax, a small area in the lung that is filled with air, called a bleb, ruptures, causing the air to leak into the space around the lung. This buildup of air puts pressure on the lung, so it cannot expand as much as it normally does when you take a breath. A collapsed lung is caused by the collection of air in the space around the lungs. March 17, 2021.A spontaneous pneumothorax is the sudden onset of a collapsed lung without any apparent cause, such as a traumatic injury to the chest or a known lung disease.

What is spontaneous pneumothorax? American Journal of Respiratory and Critical Care Medicine. In: Tintinalli's Emergency Medicine: A Comprehensive Study Guide. Sometimes air may continue to leak if the opening in the lung won't close or pneumothorax may recur. Potential complications vary, depending on the size and severity of the pneumothorax as well as the cause and treatment. Anyone who has had one pneumothorax is at increased risk of another. Certain types of pneumothorax appear to run in families. The risk increases with the length of time and the number of cigarettes smoked, even without emphysema. Underlying lung disease or mechanical ventilation can be a cause or a risk factor for a pneumothorax. ![]() The type of pneumothorax caused by ruptured air blisters is most likely to occur in people between 20 and 40 years old, especially if the person is very tall and underweight. In general, men are far more likely to have a pneumothorax than women are. The ventilator can create an imbalance of air pressure within the chest. A severe type of pneumothorax can occur in people who need mechanical assistance to breathe. These air blisters sometimes burst - allowing air to leak into the space that surrounds the lungs. Small air blisters (blebs) can develop on the top of the lungs. Cystic lung diseases, such as lymphangioleiomyomatosis and Birt-Hogg-Dube syndrome, cause round, thin-walled air sacs in the lung tissue that can rupture, resulting in pneumothorax. Lung damage can be caused by many types of underlying diseases, such as chronic obstructive pulmonary disease (COPD), cystic fibrosis, lung cancer or pneumonia. Damaged lung tissue is more likely to collapse. Some injuries may happen during physical assaults or car crashes, while others may inadvertently occur during medical procedures that involve the insertion of a needle into the chest. Any blunt or penetrating injury to your chest can cause lung collapse.
