Atelectasis is a complete or partial collapse of a lung or lobe of a lung develops when the tiny air sacs (alveoli) within the lung become deflated. It's a breathing complication after surgery. The amount of lung tissue involved in atelectasis is variable, depending on the cause. Atelectasis can make breathing difficult and lower oxygen particularly if lung disease is already present. Treatment depends on the cause and severity of the collapse.
Atelectasis is likely to occur when you're already in a hospital. However, seek medical attention right away if you have trouble breathing. Other conditions besides atelectasis can cause breathing difficulties and require an accurate diagnosis and prompt treatment. If your breathing becomes increasingly difficult, seek emergency care. Obstructive atelectasis may be caused by Mucus plug, Foreign body, Narrowing of major airways from disease, Tumor in a major airway, Blood clot. Possible causes of nonobstructive atelectasis include Injury, Pleural effusion, Pneumonia, Pneumothorax, Tumor.
There may be no obvious signs or symptoms of atelectasis. If you do have signs and symptoms, they may include: Difficulty breathing (dyspnea), Rapid, shallow breathing, Coughing. A recent postmortem study of lung tissue samples from 98 Mexican children aged less than 2 years who died of Atelectasis, which used nested polymerase chain reactions, showed that 30% were positive for respiratory syncytial virus: 62% of those with histopathological diagnosis.
