What Causes A Collapsed Lung
No.: An emphysematous bulla or"blister" occurs by the systematic destruction of the interalveolar septa within the alveoli with the resulting coalescence of alveoli resulting in the dissapearance of lung tissue. The most common cause is smoking although some individuals nay be born with congenital blebs(4cm or less) or bulla(more than 4 cm).

Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Injury or luck: Ok, not really luck. Some people are prone to "spontaneous pneumothorax" where the lung collapses on its own. Other reasons include injury, infection. Treatment may include drainage with a tube or even surgery. Treatment options depend on cause, patient symptoms and conditions. More information necessary to properly answer this question. ...Read moreSee 1 more doctor answer
Defect in the lung: Though most of the time when a lung collapses, it is caused by some type of trauma, there are some patients that have defects in the lung surface. These illnesses range from emphysema to lung fibrosis. There are some genetic mutations that also have been associated with weakness in the surface of the lungs. If the collapse of the lung was unprovoked, your doctor may need to do some tests. ...Read moreSee 1 more doctor answer
Multiple: External and internal. External causes are trauma, diagnostic procedures, etc. Internal factors deal with an increase in pressure in the lung, causing rupture of a pre- existing issue (pulmonary bleb). Pressure increases can be a cough, sneeze, or being on a ventilator. Air leaves the lung or enters the chest through a defect, causing collapse of the lung. ...Read more
Lung collapse: A collapsed lung can be spontaneous and associated with a variety of diseases (emphysema for example or alpha-1- antitrypsin deficiency) or traumatic. Various conditions can result in which if untreated the lung may remain collapsed or produce a tension pneumothorax demanding emergent treatment. ...Read moreSee 2 more doctor answers
Varies...: Most commonly it is from either trauma that can result in increased pressures in the chest or rib fractures that tear the lung. The other common source is bleb or bullous disease of the lung. Imagine an overinflated balloon ready to pop. Something causes it to have increased pressure and air then leaks out to cause the lung to collapse. Other reasons can include cancer and bad emphysema. ...Read more
Loss of (-) pressure: A collapsed/punctured lung is serious, as it can progress to tension pneumothorax. Once recognized, a chest tube is placed to release the pressure associated with collapsed lung. Any injury that allows positive pressure from the airways or externally into the negative pressured pleural space will start the lung collapsing. Trauma, needle sticks, rib fx, fluid, spontaneous are common causes. ...Read moreSee 1 more doctor answer
Collapsed lung low O: A collapsed lung doesn't oxygenate blood, so a person with one feels very short of breath. The damage to the person comes from the oxygen problem. Once the lung is re-inflated, it usually goes back to working about as well as it worked before. Sometimes the collapses come in people with lung disease, so that might not be very well, but they also occur in young, tall, thin athletes. ...Read more
Multiple causes: Common causes include chest trauma (like a car accident or a puncture wound to the chest) or medical procedures (like intubation). It can also occur as a complication of lung disease such as emphysema, pneumonia or cancer, or it can happen spontaneously. Typical symptoms include sudden onset of shortness of breath and sharp chest pain made worse by inspiration. ...Read moreSee 2 more doctor answers
Air leak: Anything that could cause a hole in the lung can make it collapse. The most common causes are trauma, bleb disease (weak portions of the lung like an overinflated balloon), and postprocedure changes. People with blebs can get it from heavy coughing or straining to have a bowel movement - anything that increases the pressure inside the chest. ...Read more
Yes: A collapsed lung (known as a pneumothorax) can cause subcutaneous emphysema when air moves from the chest through muscle and into muscle planes below skin. Subcutaneous emphysema is usually a sign that a pneumothorax is present. Typical signs of a pneumothorax include dyspnea (shortness of breath), chest pain, and fast respiratory rate. ...Read moreSee 1 more doctor answer
Both are affected: Normally, in pulmonary fibrosis both lungs are affected at the tissue level. The x-ray can show one lung more affected than the other. Confusion can occur when a doctor calls an old scar pulmonary fibrosis. In these cases, there should be no further progression of the scarring. ...Read moreSee 1 more doctor answer
