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
Negative pressure: You can die from collapsed lung, as it progresses quickly to a tension pneumothorax. First responders, emt and trauma providers are trained to recognize and release the pressure associated with a collapsed lung, to prevent tension pneumothorax. A chest tube is inserted into the space between your lung and chest wall. The tube is put to negative pressure, so lung can re-expand. ...Read more
Don't smoke: Non-trauma, spontaneous pneumothorax (sp) occur as a result of an abnormality in the lung tissue. Risk factors for primary and secondary sps include: smoking (including marijuana), tall thin stature in otherwise healthy, connective tissue disorders, pregnancy, familial history. Sps are associated with 20-40% recurrence rate (depending type). ...Read moreSee 1 more doctor answer
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
