Atelectasis

From WikiMD's Wellness Encyclopedia

Atelectasis refers to the partial or complete collapse of a lung, resulting from the failure of the lung tissue to fully expand. It could be caused by various factors including blocked airways due to a tumor, mucus, or foreign objects; infections such as pneumonia; lung diseases; prolonged bedrest with inadequate breathing; or effects of general anesthesia. The condition, in some cases, is also referred to as a collapsed lung.

Risk Factors[edit | edit source]

The risk of atelectasis can increase with certain factors or conditions. For instance, premature infants with undeveloped lungs may experience atelectasis due to respiratory distress syndrome. Other risk factors include smoking, obesity, sleep apnea, or underlying lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), or cystic fibrosis. The condition is also more likely to occur post-surgery due to the impact of anesthetics on lung function, or because pain can inhibit deep breathing.

To mitigate the risk of atelectasis during and after surgery, medical professionals may suggest quitting smoking, engaging in breathing exercises, administering certain medications, or employing breathing devices like a CPAP machine.

Symptoms and Diagnosis[edit | edit source]

Atelectasis may remain asymptomatic if it only involves a small section of the lung. However, if a large portion of the lung is affected, symptoms such as fever, shallow breathing, wheezing, or coughing may manifest.

Diagnosis usually involves a chest X-ray, which is the most common method employed. Additional confirmatory tests can include a bronchoscopy or other imaging techniques.

Treatment and Complications[edit | edit source]

Treatment of atelectasis primarily focuses on re-expanding the collapsed lung tissue. This could involve breathing or coughing exercises, inhaled medications, the use of breathing devices, or in severe cases, surgery.

Generally, atelectasis tends to improve with time or appropriate treatment. Nevertheless, if it goes undiagnosed or untreated, it can lead to serious complications like fluid accumulation in the lungs, pneumonia, and even respiratory failure.
