Causes And Symptoms Of A Collapsed Lung
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
Atelectasis (from greek: ἀτελής, "incomplete" + ἔκτασις, "extension") is defined as the collapse or closure of the lung resulting in reduced or absent gas exchange. It may affect part or all of one lung. It is a condition where the alveoli are deflated, as distinct from pulmonary consolidation. It is a very common finding in chest xrays which needs to be interpreted in the ...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
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
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
Collapsed Lung: An obstruction inside the airway may prevent expansion. Alternatively, the lung or the lining around the lung could be inflamed or scarred. ...Read more
What causes a collapsed lung? Can this just happen out of the blue or are there specific behaviors or conditions that cause this?
A : A collapsed lung - also referred to as a pneumothorax in the medical literature - arises when the outer surface of the lung develops a "puncture" causing the lung to deflate. A pneumothorax can develop in certain medical conditions where the lungs are diseased and prone to developing a "puncture" --e.g. Asthma, cystic fibrosis, and emphysema and is more common in smokers. Sometimes a pneumothorax arises when there is no apparent underlying lung disease. This is referred to as a primary spontaneous pneumothorax and is typically seen in young, thin men. Sometimes having a family history of a collapsed lung can suggest a cause, and there are some rare inherited diseases such as marfan's syndrome in which a collapsed lung can occur out of the blue. Stopping smoking is the only specific behavior that will significantly reduce your chance of developing a collapsed lung. ...Read moreSee 1 more doctor answer
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
